[DIY] Sound from PC to android and PC headset to android - Hardware Hacking General

DIY adapter to use your PC headset in your android :cyclops:
You will need
- 2 female TRS
- 1 male TRRS
- Wires! I strongly recommend USB wires
Ok just weld everything... yes is simple. But how :silly:? Take a look in the pics.
"The original TRRS configuration was created by Nokia and has a pinout", from TIP to SLEEVE, "of Left Audio, Right Audio, Mic, Ground".
=====================
DIY adapter to pass audio from PC or other hardware to your android with male-to-male audio cable
You will need
- 2 female TRS
- 1 male TRRS
- Wires! I strongly recommend USB wires
- Male-to-male audio cable
- Soundabout
Ok just weld everything, everything except the MM and Soundabout ... yes is simple. But how :silly:? Just like the above but also look here first:
"Apple came along and in typical elitist fashion changed their pinout to", from TIP to SLEEVE, "Left Audio, Right Audio, Ground, Mic".
Then this adapter is exactly like the first above, but you will need change the Mic Right to Ground.
To force android to receive the input audio when you plug the male-to-male cable, you may use Soundabout.
Through this configuration you can send audio from any TRS output to your android, then the audio will be captured like a microphone.
=====================
The difference between both is only the MIC and GRND position in the TRRS male. They are switched. By mistake I switched and now I have 2 useful adapters.

FIRST OLD POST :
Hello knights.
My country are in such a chaos because of the manifest and I'm here mess around with technology... but I'm doing my part too xP.
Anyway, in the last days I was searching and testing a way to send the sound played in my computer, or other device, to my little android (codename Smultron).
With a 3.5mm cable (TRS or the one with 3 contacts) male to male, I plugged into the audio output of my Dell then plugged to my Mini, I started the app to record and... nothing.
Few days later, I used the app Soundabout and... nothing.
More few days later, I did the same thing BUT I don't put the cable until the end, I pulled out a bit, so the 3 contact of the cable stay full visible and... works! I was able do record the audio input of my laptop.
Also, with Soundabout, I was able to stream the audio from my computer to android calls!! For example, if you call me and I answer, if with the cable plugged I play some music on my PC the caller will clear hear what is playing in my computer.
In one more test, I used the MM cable and a splitter. With the Splitter and the cable I was able to stream audio from PC to android mic AND hear the android with a regular earphone, this test was made with a call in course, of course.
But this is only possible because in some way the PC are sending the signal with some extra power. If you try the test with a regular pc headset, without the computer this won't work.
"So why are you here if you did this you noob?" - Well I not figured out why or how the conectors are working when the stream are succesfully done. So I'm here to extend a bit this little research and ask for some help with who master this things. Also I wanna share with you all.
The keys of this are the jack conectors circuit and contacts combinations, and android audio routing using a app like Soundabout.
The main point, in other words, is how to made a DIY cable to stream audio from pc to android mic and with a splitter enable the audio output.
The reason that I'm searching for this is because initially I was looking for a way to did a DIY adapter for PC headphones with two jacks to android input, for single jack.
--
One more little thing, for the people that want to record a call without android modifications, you can plug the same male to male cable to PC MIC and start the sound record app of the Windows, for example.

I was wondering if one of the rings touch the microphone pin inside the jack input and the tip won't touch anything. If the contact of an output was plugged to contact the mic input we got audio from external source to phone...
This is the average TRRS circuit in our mobiles? TRRS circuit

It sounds like you made contact with the input pin, so you might also be contacting an output pin. I'd get a headset adapter cable, so you have an input and output 3.5mm jack.

Hummm.
I found some stuff
see the second jack
I finally found something like this
and this
Electro I agree, but I don't found the adapter easily here, so this is one of the reasons of why I want do a DIY.
But you said, I will ask: someone can do the test to send audio from pc to phone through the adapter and with a M to M jack cable?
I will try to found a nice way to do it as an DIY.
I wanna know how this exactly works, If I was searching for ready solution I would be an Apple's zombie xP.
I think I found what I need, let me do something here.... thank you guys. If anyone have more to say please feel welcome.

Yeah I nailed it!
I made a DIY adapter for PC headphones to android (at least the Xperia Mini) and a DIY adapter to send audio to android trough a male-to-male cable. Soon I will post pictures.

USB Mini to (the other) USB Mini (?)

I have a a USB mini extension lead, so I'm trying to plug in a 3-to-1 adapter to it. So male USB mini, the a-symetrical type (flat one side) to a female USB mini, the symetrical type (wings on both sides). Obviously this doesn't fit!
So is there a USB Mini (female a-symetrical) to USB mini (male symetrical) adapter?
Or could someone at least tell me their proper names so I can google it?
What are you trying to achieve? If it is to increase the cable length between the 3in1 and the Kaiser, I think you would need an ExtUSB patch lead with all 11 pins wired to retain the functionality of the 3in1. I don't know if these leads even exist.
The Asymetrical female socket, like the one on the base of the Kaiser, is double sided on the internal plastic "island" and has 5 contacts on one side and 6 contacts on the other.
The power and data are on the top 5 connectors.
The audio in/out & talk/end are on the bottom 6 connectors.
This is known as ExtUSB and is peculiar to HTC devices.
The Symetrical plug/socket is standard mini USB and will only ever have power and data connections. The mini USB plug only connects to the top 5 connectors in an ExtUSB socket.
Ouch, my dreams of the perfect in-car system dashed! Thanks wizzard that's really explained it very well.
The objective is to have a nice looking car install with only one wire leading to the Kaiser, and the 3-in-one hidden. So ideally:
Power \/
Audio > 3-in-one >> USB extension >> Kaiser
Hands free /\
It was hard enough finding the mini USB extension, so as you say an ExtUSB extension lead may not even exist
I purchased this adaptor for less than £10 from ebay. It ticks all the boxes for me and is the most discrete adaptor I could find. The 3in1 adaptors like this one dont come with a mic so wont work as a hands free without additional adaptors.
My intention is to have the plug fixed to a Brodit mount. The cable is no thicker than headphone cable. This 90cm cable will route to behind the steering wheel on the cowling. The adaptor is flat and low profile with the answer/hang up button on the top. Easily pressed through the steering wheel spokes. The audio 3.5mm and mini USB leads plug in at right angles to each other but will easily route out of site, behind the dash to USB car charger and 3.5mm MP3 In socket on the head unit.
It all works as expected, and even at Motorway speeds callers can hear me clearly. Voice Command works fine, TomTom and Media Player sound great. My only problem is alternator whine when charging, which I think is just an earthing problem. When I get it all properly finished I will post some photos.
After work, wife, kids etc. have finished with me.
Thanks Wizzard. Not a bad solution, and the best so far without the existence of an ExtUSB extension lead.
My only problem with it is that (I assume) it forces the kaiser into handfree mode even when all I was to do is charge and listen to music from the 3.5mm connection.
Again, I am assuming here, but I thought the second adapter you cite would only initiate hands free when I plug in the hands free into its port. I could be wrong on that one though.
Perhaps my issue is a small price to pay for 8gbs of music in the car

I dont have the bulky 3in1 to test, sorry. For me when listening to music and TomTom the audio mutes when I take a call and then resumes seamlessly on hang up without needing to physically touch the Kaiser. I only need to touch the Kaiser to press the Voice Command key once to launch programs and initiate calls.

Hi!
Unfortunately the link to the item you have is broken...
I'm trying exactly what you wanna do, I bought this extension.
Is this the same of you?
It works, but I have annoying noise on audio when it's connected to the USB power jacket.
How to fix this?
Thanks a lot.

mbarabas, szerintem a csomagnak nem része a tv kábel, de ne legyen igazam, mert én meg akarom venni a pro-t
mbarabas, according to me for the packet not his part the TV cable, but not be true, because I want to buy it the pro
I'm sure I saw somewhere that it doesn't come in the box. I've just oredered one from Expansys.
Today is the last day of the Modaco offer if you type "http://mickey.modaco.com/expansys/getcode.php?email=" into your browser adding your email address after the "=" it will send you a £10 voucher. You need to order something else to push the price of the cable over £20 so I got a 1GB MicroSD.
So all in that's a the TV out cable and 1GB MicroSD card delivered for £14.19
HTC own website states that its optional, so its highly unlikely you'll get one in the box
My cable has arrived. I'll post the pinout when I get a chance to beep it out.
pin out
These are for the pins as viewed in the plug.
1 video out
5 video ground
2 audio right
6 audio left
11 audio ground
jwitham - thanks, updated first post!
Now does anyone know where you can buy the 11pin ExtUSB plugs from? I only seem to be able to find them on audio adaptors which, I guess, only have 3 wires connected.
I was watching unboxing video, there is not a TV cable in the box
not really what the post is after but might be useful for some people, here is the link to buy the full cable from expansys:
http://www.expansys.com/p.aspx?i=170917
make one?
The HTC TV out cable cost too much! ($50)
Im gonna try my luck and make one.
Ebay sells 3in1 HTC ExtUSB adapters for about AU$15 shipped (it does say 5+6pins)
http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&rd=1&item=370079511111
and Dealextreme have Yellow+Red+White TV-out cable for a samsung phone for $5 shipped.
http://www.dealextreme.com/details.dx/sku.5122
Should be able to use the diagram in post#7 and get it to work.
anyone see a problem with this approach?
i heard that raphael detects video-out cable presense, so there probably should be some king of resistor or somthing like that... we need to check that.

yeh, to check resistance between video out and video ground, as well as
between audio out and audio ground, for example, by some ohm-meter

probably a terminator resistor of 50 ohms .. a piece of 50 ohm antenna wire will do fine ..
these cost 25 cents or less
as far as the mini usb .. its probably the same as this one motorola has..
im not sure if motorola sells these or if there are any to buy separatly.
just an idea : maybe one can convert this yellow rca videoplug (which comes standard with any videocard with tv-out) to have a miniusb plug on the other side.

No problem what to convert, the question is "how"
An ExtUSB-3.5mm jack headphone adapter ($5) has the necessary connector.
I just need someone to check the original cable of intercontact resistence

I dont think it is terminated inside the connector. The detection will be due to the internal termination of the device you connect to eg tv or projetor.

I think you are right a tv has an composite input witch has a 75ohm resitance.
but your headset uses the same connection for his mic... for me a bummer but for you guys maybe the solution....
take a look at this link:

it's a pinout of the headset...
i just maked one for myself (actual a home made cradle) but it just doesn't reconize the cable, audio and charging works like a charm
Build your own TV Out Cable
OK, I tried to put the pin-out together. I don't have the cable, but I played around with the Multifunction Audio Cable YC A200 which I opened up for that purpose. Only when pins 3 and 5 are connected and not 4, the TP recognizes a video cable and askes for the video norm. When using these pins as ground, there is a humming noise and the video flickers. By connecting these pins with pin A, this problem is solved. I put the info on a figure... could someone with a cable and a multimeter validate it?
I made then a custom cable to work with the Multifunction cable. For this, a 4-pin 3.5 mm plug was worked on with a Dremmel (see figure). The plug needs then to be inserted into the receptacle so that the notch is at the upper left. Just turn the plug till it is no longer identified as headset but as video cable. The extra ground connection I got from a regular mini USB cable. Tested and works without problem...
switch should be connected to mic ground probably.. can you try if this works ?
connect 3 and 5 for video switch
connect audio plug [ ]=== ground - audio right - audio left
4 - 2 - 6
connect video (o) outer 5 inner 1

USB Mini A B extension cable?

Anyone find a source for USB extension cables for the Touch Pro? I want to run a cable in my car from my touch pro mount to the center counsle where I will have the audio dongle. which will branch off to a charger and line out to my Aux in. Otherwise I have to have the exposed audio adapter and then two cables running out of that instead of the one single extension cable I want to run to the center console. Really hoping I don't have to build my own.
I suspect this will be hard to find, considering it's not just a standard mini USB cable.
I like the idea behind it though. I was thinking about the same type of thing in my car and I'm waiting on getting a couple different docks so I can see if they will fit my needs once I rip them apart.
You need an extUSB extension cable. It should be around $10-$30. Depends on where you get it from. I'm thinking try eBay/expansys-usa/htc store

Been looking at all the normal sources, the problem is I need it to end in the same female plug that is in the Touch Pro (so I can plug the audio dongle into it). Having zero luck finding it.
I have to disappoint you: if you connect both the audio and the charger from your car, you'll get a loud noise because of lack of grounding in car

3.5mm MICROPHONE jack adapter

Hi everyone, I have the following issue:
I installed a guitar tunner application in my handheld, which uses the microphone to capture the sound. Since I play in a rock band, it´s very noisy when we are setting up, rendering this tuner useless unless everyone shuts up (which never happens).
I have used tuners for the PC, where I plug the guitar directly to the pc's microphone input (just using a 6.3mm to 3.5 mm audio jack adapter), the results are superb, so I was wondering if this could be done with my htc. I searched ebay and found many mini-usb 3.5mm jack headphone adapters with built in microphone, but none that allow me to use a different microphone.
Is there any microhone adaptor out there?
If there is any other way to do this I would love to try it, any ideas??
Thanks!!
Solved...
4Pockets guitar tunner works just as good as my PC tunner and is more responsive than the $25 chromatic tunners sold out there. It also allows me to connect my phone to any sound system and record music with (by far) better quality than using the phone's built in microphone and placing it next to the speakers.
Just in case anyone is interested on how to do it, this is the procedure I followed:
- Buy any inexpensive hands free with 3.5 mm jack and integrated microphone, there are many on ebay at less than $3 incluiding shipping.
- Open the hands free on the microphone side, you should see the microphone, a push button (to answer calls) and the 3.5 mm jack.
- The jack has 3 cables soldered on to it, remove the two that make contact with the tip and center of the plug (this leaves only the ground cable connected to its base, which is probably black)
- The microphone has 2 cables, one is ground and is probably black, remove the other one and solder it to the jack, in order for it to make contact with the tip of the plug (make sure it's on the tip and not in the center contact).
- Make sure the exposed tips of the cables you removed from the jack don´t touch any other cable.
- Seal the adapter
- Voilá, now you have a mini-usb microphone adapter for your HTC.
I don´t know what could happen if you make a short circuit, and i'm not willing to try it.
Cheers!!
woot that was cool
does that hack work with google nexus one or any other phone i wan to input sound from tv when recording with the cam

USB headset not supported by device?

I plugged in (for the first time ever) my usb headset that came with my blackstone, and i immediatly get a message saying 'Warning, The device does not support usb headset please remove' !!
any ideas?
There is no sound out of the USB connection, please use the 3.5 headphone socket.
am i being a bit thick? i got usb earphones with my blackstone that you are now saying are not compatible?
i didnt get a 3.5mm headset to use, just the usb one.
what am i supposed to do with the usb earphones then?
were did you get you device from
i got it from buymobiledeals.co.uk on uk orange contract
can you post a picture of what you got in the box and the boox itself
Doh! My partner just got a kaiser and I thought her headset was for my phone! Found my 3.5mm earphones in the box, guess i was being thick!
sorry for wasting your times guys, but thanks for your help.
well it happnes to the best of us
Hah, that sucks. Yea, There are dev's trying to get the usb slot to work how it should so later on you can do that. but not now

it was my understanding that although the extUSB socket has the ext pins, they are not actually connected to anyting on the blackstone side, so without a bit of hardware and some soldering skills, it wont be possible to ever enable the 'ext' part of the extUSB port
what i find funny is everyones major sore point with HTC is the use of the usb audio. now they finally give us a device with 3.5 jack and were trying to get it to work with usb

Agree - now we have a great 3.5 socket with socking sound there's loads of people who want USB sound. Once HTC provide USB sound I want a micro SD sound output channel !
lol
it did seemlike all i heard as far and cons go with htc was the usb headphones
I think its great they give us a 3.5 port. Just put it on the bottom so car holders can incorporate it for quick simple connections. Guess I'll need to set up bluetooth audio for my in car use. Hate to plug in extra plugs to get audio out.
