Hi,
I'm only 13 and a proud owner of an O2 XDA 2.
This I what I need help with.
I would like to place my USB docking station on top of my subwoofer, and connect my XDA with it (only for audio purposes only).
I've read some of the forums here, but didn't find much info. :?
Could someone tell me which pins, on the connector, on the dockingstation send the sound? I would like to add 2 cinch cables to these pins, and attach them to my subwoofer (to kind of make my XDA like an Ipod or another MP3 player, where I simply stick it into my dockingstation and start playing MP3s through my sound system).
Thanks,
Kind Regards,
Tony Schattat
Hi mate.
Note sure you could connect the XDA directly to a speaker as I doubt it would have the required power output (but I don't know much about this, just being logical).
Take a look at the following thread: http://forum.xda-developers.com/viewtopic.php?t=26489&highlight=
This guy has basically modified the headset to have a 3.5mm jack - I've then suggested (and intend on doing this) that you could put 2 standard audio outputs instead.
On reflection though, I think his suggestion may be better as it reduces the number of leads. If you then needed to split the sound out to 2 seperate channels you could use something like this:

Hi Wayne,
Thanks for your reply.
I would rather like to have a solution which is built in my dockingstation.
With alot of precision I was able to do the following.
1. Used http://wiki.xda-developers.com/wiki/Connectors for details.
2. On pin 19 on the dockingstation I placed a 10K SMD resistor (as the standard ones are too big), connected to GND, as stated in the text.
3. Using a double cinch cable I soldered them onto pins 3 (CAR_AUDIO_R) and 4 (CAR_AUDIO_L), and both GND wires to GND.
But nothing seems to work.
I used the ohm-metre to check if the 10K resistance even came up to pin 19 of the dockingstation. I does. Unfortunately the XDA doesn't turn off it's built-in speaker and microphone, as stated in the text.
This basically simulates a car-kit for the XDA, doesn't it?
Kind regards,
Tony Schattat

Hiya!
Well if yer are 13 then it seems UK Schools are way behind German ones if they're teaching you about using Ohm Meters, Resistors and electronic theory already!
Ok, overall to me this whole precision soldering and resistor checking etc is all overkill for what you ultimately seem to want to achieve.
I've just bought off eBay the little 2.5 mm to 3.5mm standard headphone jack converter lead for about £2.50. I'm going to go nip into a shop or again off eBay and get a 3.5mm stereo to 2 phono plug convertor lead.
Simple case of then slapping that into the Aux input of my Hi-Fi amplifier, or my mini deck hifi etc and playing the mp3's through that!
No need for faffing around with soldering irons, and electronic theory and all that!
Added benefit is of course that through the hifi unit, I have full control over the audio equaliser functions and so will have the full spectrum of audio frequencies to hear the music - Your requirements states you just want to connect it to a subwoofer. Low frequencies are great, but you do need the upper frequencies too!
That will all set you back the grand total of about £5, and i've assumed you do have some audio equipment with an Aux input!
For 'constant' playback, when yer battery gets flat,... just plug the charger in!
Another benefit is that you can take the leads with you on your travels and setup the same at any of your friends houses with minimal effort!
I don't see the point of the route you are wishing to take - unless I'm missing something (I got in at 7am this morning after clubbing and up at midday, so im knackered!)
Cheers!
Hope this helps!

Hi Dennis,
Well the schools here aren't all that far ahead ( I think, because I`ve lived in Australia for 6 years)!
It runs in the family!
I was able to find some handy info on some dockingstations on google, but I'm not very sure.
Is it true that the serial dockingstations have an audio connector on the rear side, opposite of the power connector?
Is the audio connector on the dockingstation the same thing as the one, which is found at the bottom of the XDA (would it disable the built in mic and speaker of the XDA and send the audio through connector on the back)?
If this is true, could I simply attach a 2,5mm to 3,5mm converter to the back of the dockingstation and attach the converter to my subwoofer?
Kind regards,
Tony Schattat

Hi there Tony
I'm still not sure exactly why you want to connect your USB cradle to play music through.... seems pointless to me..
The method I described would be the easiest for you to 'amplify' the audio output from the XDA2.
I may be wrong but I dont think the USB cradles have an 'audio output' connector at the back, it's a bit pointless as these devices aren't devised as 'audio players' - so no, you cannot put the 2.5 to 3.5 mm converter on and then connect that to your subwoofer (signal is wayyy wayyy too small to drive a sub woofer) if there is an audio output at trhe back of the usb cradle, then I never knew about it!! and same again, you cannot connect directly to a sub woofer.
Out of the socket at the bottom of the xda2 in a 2.5mm size, is an audio jack. Get the converter to take that 2.5 mm and output it to a standard 3.5mm headphone socket size. Right, at this stage you can connect 'Hifi' headphones and enjoy your MP3's that way. If you now want your music 'louder' you need to convert that (now) 3.5mm output to be able to connect it to some audio equipment that can 'amplify' the signal and play through some loudspeakers (the 3.5mm socket to Phono converter lead). That will go to your hifi amplifier in turn to which 'full range'loudspeakers are connected. You mention 'sub woofer' .. You could then attach your sub woofer to the amplifier and you will only hear the low 'rumble' of the bass frequency content of the music (again, a bit pointless!). If that's what you want then at this point all will work but then what's your plan for hearing the mid range and high frequency elements of the music?
I'm just thinking that for your final 'aim' (to hear MP3 files on the xda through loudspeakers) the method you are using is cumbersome, time consuming and pointless when you can have a 'full range' output using the method I described.
Take a look at eBay for the connectors - and you'll find you should be hearing music in no time!

I just got a new car that has an auxiliary jack that says I can play my music from MP3/Ipod players. I bought myself a 3.5 mm cord, plugged it into the HD and the Auxiliary port in the car stereo, but there's no sound.
Is there something else I need to do in order to hook my Blackstone up to my car stereo's Auxiliary jack? I figured the 3.5 mm Auxiliary port would just hook up to the HD's headphone jack as if the stereo would act as headphones. Am I wrong?
With mine, I just plugged the 3.5mm jack into the HD and every sound even phone calls automatically came through the cars speakers.
Try plugging another device with a 3.5mm jack into the car, if there is still no sound the theirs either a setting on the head unit or cable may be faulty.
Here is the cable I used, connected directly to the back of the head unit using RCA connectors.
http://catalog.belkin.com/IWCatProductPage.process?Product_Id=172348
Hmm, does sound (sorry) like a cable problem. I have plugged the HD into external speakers via the 3.5 socket with no problems.
What you are aiming for should work but the cable needs to be right.
You probably have to go to the option on your car stereo. It's just like changing from the fm receiver to the cd player on your car stereo (except you have to go to aux-in).
Look in the car stereo manual how to activate the aux-in option.
If Headsets work fine on your HD this should work as well.
Then it's not a problem with you phone.
Thanks for the replies, everyone. I did switch it to the "Aux" function as opposed to Radio/Satellite/CD/Etc., so I'll see if my son's iPod Touch works or maybe there's something else I have to do with the stereo in the user manual. Otherwise I'll assume the cable is faulty. Hope my wife didn't throw out the packaging just yet! It was just a cheap $7 retractable one I got from Target. Next option is a 3 foot $15 one.
Also, make sure you connected the cable to the aux-in on the stereo and not the aux-out. This isn't always indicated in a clear way (I'm just thinking what it could be).

Yep, thanks for the input. Luckily it's pretty idiot-proof. It's the manufacturer installed Bose stereo system in a 2009 Nissan Rogue. There's only one input on the front face of the stereo panel labeled "Aux In". And you press a button labeled "AUX" to use it as far as I know. Pretty handy!
i have the same problem with my Alpine stereo,has an AUX Input,Even when i enable aux on the head unit still no sound.Taken it to my local car audio garage and theyre baffled!
Later said to me it could be a faulty HU
Ah, well I am used to after market stereo's with the connections on the back (rca connection).
Sorry that I'm not able to help. Well as long as you get sound through headsets and such it is not a problem with the HD, but I guess you figured that out.
Sadly those RCA's are usually outputs for an amp :'(
I'll test my son's iPod Touch today with the cord and see if his works. If his doesn't work also then I'll try a different 3.5 mm to 3.5 mm cord. If THAT doesn't work then I'll have to assume the stereo is malfunctioning.
Another thing that crossed my mind is what if the headphone jack on the HD doesn't produce enough juice to feed into the stereo. Would that be possible? Although it sounds like others are able to get theirs to work, so I'm assuming the HD puts out enough.
Thanks again for the quick input, everybody!
when you plug the lead into the touchHD, you do get the liitle headfones show up on the topbar of the screen?
you havent muted the media player somehow?
you have removed the 100dB eurolimit on the HD output yes?
vol on the HD is around the 80% on both media player and general system sound?
AUX is actually enabled on the headunit in the car? on my factory fitted headunit, the aux button is switchable between the aux line in and an external cd player... if you have the manual for the headunit, have a look to see if there is this option
the headfone jack on the HD pushes out plenty of power, especially if the 100dB limit is removed (hd tweak or advance config... dont forget to disable audio booster and the EQ as that will really mess up the sound)
The price tag and the lack of software (so far) are holding me back from getting one of these bad boys. I've seen some videos of the modded/hacked Q's and that is very promising.
I do love the built in amp feature. I used the heck out of airplay for music with my iPhone/appletv. I moved on to the Galaxy Nexus and think the Q would be great because I could bypass having to turn on a stereo. I also have a powered subwoofer that automatically turns on when something is being played. I was wondering if anyone else is using one in their setup.

Good question - just bought one and didn't even think about hooking it up to a powered sub (lacking a legit system at the moment) Subbed
I have 2 Kef xQ10 loudspeaker plugged to the Q. It sounds fantastic ! I'm really impressed by the small amp inside the Q.
But it really miss some subwoofer. But I wonder how I can plug it to the Q ? Any idea ?

My powered subwoofer, along with most nowadays, have line out connections. You'd connect the Q to the subwoofer first, the left and right connections. The sub will use its own power and you'd connect your 2 speakers to the sub. It should work that way, I think!
I have mine connected to my sound bar via the hdmi cable i got with the Q.
Sent from my Galaxy Nexus using xda premium
Both ways have been mentioned:
1) Use an intermediate device to decode the HDMI audio, send it to speakers including the sub. (Most people use a receiver on an existing setup. Hubono mentioned he uses his soundbar.)
Advantage: You can use big speakers / better sound.
Disadvantage: More remote controls & power required.
2) Buy a sub that sits between the amp (Q) and the speakers. These have jacks for connecting the speakers to the sub, and then connecting the speaker wire to the Q. They will look at the speaker signals to create the music. See below for an example back panel:
http://www.polkaudio.com/images/products/gallery/747192120269_7.jpg
Advantage: No remotes!
Disadvantage: Not all entry level subs turn off with no sound.
ETA:
I have a pair of Polk Monitor 30s on my Q. While sounding good, they in combination with the Q definitely lacked bass for music. I moved my PSW10 inline (option 2), and now music sounds much better.

I connect everything to the sub via HDMI
Yes, I currently have mine plugged into my receiver via HDMI, which is connected to my 7.2 system. It works pretty well.

If you have a sub with speaker level inputs (as many sony's do) then you should be peachy
Hi, I installed a MTCD Android head unit with Android 5.1.1 in my car two weeks ago. (I could'nt start this thread in the MTCD section because I'm new here)
My car audio setup goes as follow: Android Head Unit >>> USB Cable >>> PCM2704 USB to SPDIF adapter >>> SPDIF coax cable >>> MiniDSP 6x8 >>> 3 Amps >>> Speakers + sub.
So far I've been able to get SPDIF sound output with Neutron (Direct USB mode), Onkyo HF Player, USB Audio Player Pro, HibyMusic Player.
Sound is amazing btw.
If I understand correctly, all these apps are working with the USB DAC because they use their own app's USB Driver.
Important to know: All song in 44khz are playing fine, songs in 48khz makes every app freeze. I got a way around this by setting Neutron to resample every song in 44khz, so all songs are working now.
Now, if I play a song in Google Play Music, Spotify, Kodi, etc no sound comes out ... same thing for my HU video app, phone calls etc.
Is there a way around this ? What modifications can be made so every sound outputs to the USB Audio ? IE. kernel update, system files modifications etc ??
Thanks for any input.
Nobody use a USB DAC with his head unit ?
I have found this thread: http://forum.xda-developers.com/showpost.php?p=66707293&postcount=47
But I dont think it applies to Android 5.1, sound management is different.
i dont use any DAC on this head unit. But I do have a Dragonfly USB DAC on my computer. the Dragonfly Red says it works with Android. Not sure if that is just marketing, or if it doesn't something specific.

you would need to be using pre-outs, using a 3.5mm to rca cable into an external amp.
---------- Post added at 09:03 AM ---------- Previous post was at 08:57 AM ----------
interesting that you've tried this. This forces you to completely by-pass the HUs sound processing.
I have the same DSP, but I'm using direct pre-outs. I like this idea though bc it gets around the low pre-out voltage, and allows you to ignore the poorly implemented sound processing in the HU.
Unfortunately, you probably need to modify the filesystem to get this to work, as your link shows. Why do you feel the need to use a DAC in addition to the DSP?

my sub is tapped into my speaker wires, so I dont use the RCA preouts. So I probably can't try this.
However, I think my audio is pretty great with the Joying

We just need to know if audio is outputing from the DAC.
I would appreciate, thanks !

The DAC is a really clean source signal VS the head unit, I have a 2000$+ sound system in my car and sound quality is very important to me.
Also, DAC is digital signal VS analog RCA outputs on the head unit.

I agree. I feel like right now my HU is the "weak point" of my system. I am about the same as you, roughly $2000 in equipment (probably a little more).
focal KRX3 3-way active system w/ a cheap kicker sub + 3 amps. I have the C-DSP along w/ a line driver to manage the low pre-out voltage. Would love to take the line driver out of the signal chain if I could. All these components are taking up a lot of valuable space.
I hope you figure this out. I don't have a MTCD, I have a non-joying 4.4 HU. Would love to use the SPDIF inputs on the C-DSP as opposed to the ****ty pre-outs from the HU.

Nice ! I have 3 way peerless (tweets + 3.5 mids + 7in woofer) 1 pioneer amp 4ch for tweets + mids and 1 pioneer amp 2ch for the woofers, another JBL amp in the trunk with a 15in Alpine Type-R. I have the C-DSP 6X8 MiniDSp as well

well you have convinced me to give this a shot. The USB DAC + 25 ft coax cable only set me back $35 on amazon. So even if this doesn't work I won't be mad.
The potential for 4V of CLEAN pre-out voltage is too enticing to pass up. The line driver works, but like I said it's another box that needs power/space/etc. The USB DAC also allows me to take the HU sound processor fully out of my signal chain.
I am unfortunately using android 4.4, so dont think I can help you much, but I will let you know if this works nonetheless.

If it dont work natively, I'm 99% sure it will work with the Neutron music player. Install it and then go to hardware settings and enable Direct USB Driver. :good:

well I tested this today and I am very pleased with the results. I really do notice a difference in SQ. It sounds "cleaner" and fuller.
Only major thing I notice is the overall volume seems really high over SPDIF. Only place I can adjust the volume now is with the DSP, but even then, I find I need to turn the gain down on the SPDIF inputs to get an acceptable volume. This is even with gain all the way down on my amps. This leads to a bit of clipping on the highs.
Did you make any adjustments in neutron player or the DSP to get an acceptable volume? Or do you get by with just adjusting the DSP master volume?
Now I just need to see if I can get all my sound to route through. I like to listen to streaming music too but I don't think I can go back to using analog pre-outs.

Great ! Now you're in the same boat as me lol
(Except for the clipping, I have no problem with that)
What is the model of your amps ? I have my gain to around 1/3 in the amps (They're up to 6.5V input sensitivity) and spdif input gain is at 0.
For your sound routing, you can sum the rca inputs and the spdif input together in the DSP And then you use your input levels to match the loudness. That way, you'll be able to listen excellent SQ music from Neutron and still hear BT phone calls, Youtube, navigation etc trough the analog inputs.

Yes! This is exactly what I have done. I spoke too soon also. The clipping was more a tuning issue than anything (changed cross-over on tweeters & lowered their output a bit). I was able to set the gain on SPDIF back to 0.
Man it sounds really good now. I haven't any real tuning yet outside of setting gains and cross-overs. I think once I tune the system it'll take it over the top.
I have a mosconi as100.4 on the tweeters and mids, and a alpine mrv-m500 on the sub. (i have one other amp I am replacing to power mid woofer, should arrive tomorrow). It's a total overkill system, but I find great deals on used gear on diymobileaudio classifieds so I keep upgrading lol.
So now I will use neutron for majority of listening, and by mixing channels together on the analogs I already had connected, I get acceptable SQ for phone calls and streaming music. I have no desire to mod my system files the way it was shown in that thread you linked. Looks too risky. I am okay with this new arrangement since 90+% of my listening is my personal music collection.
Really appreciate you making this thread. I always knew my system was capable of sounding better and this did the trick. I will let you know if I figure anything else out that could be useful.

I really think the Kernel must be enabled for USB Audio for it to work, my DAC shows up in USB devices info but not in the audio output devices.
Well, I'm still happy because my FLAC music collection plays incredibly well i dont car that much for FM Radio SQ, I only wish I'd be able to listen to Spotify or Kodi on the DAC.

Any update on this thread ?
I made some sort of experiance, on Joying HU , the 2GB Rockchip Sofia version (10.1" screen) :
Using info from https: // source.android.com/devices/audio/usb.html - i looked into the "audio_policy.conf" file on the Joying, and for sure , there was no reference to any USB audio interface.
I am no android expert .. but i edited this file , with the info gathered from the link above , and after a reboot - the HU did indeed send the audio to the USB port.
Audio from all the apps i tred , was routed to the USB interface (Radio , DAB player,Kodi etc..)
The bad thing (?) - there was no volume control , all audio is at max level.
An external volume control could possibly remedy this.. i will look into it

Hello guys,
I have a S8 Premium and i cant get the subwoofer to work.
So my connections are:
From the Atoto subwoofer output to the amplifier and from the amplifier to the subwoofer. A complete normal connection between radio and subwoofer.
When i connect the subwoofer to the RR/RL or FR/FL it works like a normal speaker but when i connect it to the subwoofer output like it shud be it doenst work.
I made a video trying to find the subwoofer settings and i cant find it, i have seen alot of videos where you can turn on/off the subwoofer, but in my atoto i dont have that functionality.
Can anyone help? Thanks guys!

Did you ever get this figured out? I found the sub settings but the output is very low even turned all the way up in the eq app.

Nice, I just ordered this one to boost up my sub output:
Install Bay - Line Driver/Line Output Converter 2 Channel - Retail Pack (IBR67), Display Products https://www.amazon.ca/dp/B01M0A124S/ref=cm_sw_r_apan_glt_i_AJGJF11KVW9Y84S2RE8Y?_encoding=UTF8&psc=1
But I really like that 3 way one idea too hmmmm.....
The Subwoofer rca output in the manual indicates it at .5 volt. Most mid model head units deliver 3-5 volt output as you may already know. The best solution is to purchase a D.S.P or a crossover, etc. Line drivers usually have alot more than 1% THD. Most name brand types of car audio have become real affordable. I use a Rockford Fosgate 3.sixty.3 that allows voltage adjustment from 2-8 volts of output. Also make sure you use a good quality rca cable that is insulated and is OFC. I use Stinger 8000 or 9000 rca cables and Sky High triple sheilded makes a good set . They make a drastic difference . I had to buy a Y rca splitter as the sub output only has one out.
opps i forgot some links

I have the same issue. I have an S8 Standard in dash. I cannot get any "Subwoofer" output from the unit. IF I connect any 2 channels from the unit to the subs amp. It works only after I have adjusted the Bass settings in the eq. But I don't have control over the Sub sounds really. However, But if I connect the single RCA "Sub Out" from the back of the Atoto S8 unit. I get absolutely no output. So I got a T splicer and connected the single Sub Out to Both RCA inputs on the amp. Still nothing. I know its only .2v output from the head. The amps input sensitivity is .250v-6v. Its a Nakamichi NKMD60.4 4 Channel amp, Bridgeable. 1500watts max. Connected to a Polk Audio DB+ 8 Inch 750 Watt 4 Ohm DVC.
But I should hear something. The gain on the amp is maxxed out. And My amp requires two channel inputs. But the head only has 1 RCA "Sub Out". So what am I missing? Is the power from the HU not enough? Or do I need a Line Booster? Or am I missing another step I don't know about. I checked the HU Sub Settings and the frequencies are within range. But still no output from that Sub jack on the back. I have a PAC LD-10 Ground Loop Isolator Adjustable Line Driver Signal Booster+10X Preamp on order. Should be here Tuesday. Im hoping this will solve the problem. Any Ideas?

hey I am in the same boat with the S8 premium, any luck with the booster? and where do you mount it by the amp? or by the head unit?
