[Q] wireless display audio - Nexus 4 Q&A, Help & Troubleshooting

I have a ptv3000 and it works pretty good for streaming my phone's screen wirelessly to my display. the only problem i have is that when i enable wireless display all the audio no longer works. seems like widi completely takes over the phone's audio out. my display does not support audio over hdmi and there doesn't seem to be a way to redirect the phone's audio to bluetooth or the headphone jack.
does anyone know of an app or setting or anything that will let me select what audio output to use while using wireless display?
Thanks.

Has anyone else even noticed this?

How exactly do you use widi?(noob question, I know)
It never recognizes my Samsung smart TV...

I don't have a Samsung TV and I don't know how/if your TV works, but on my phone I go to Settings-->Display-->Wireless Display and pairing/setup is very straightforward from there with my Netgear PTV3000.
Regarding the thread topic, I'm surprised that nobody else has commented on seeing this issue. I'm starting to think this might be a problem on my end.

I just bought a PTV3000 today. It has firmware 2.2.16 (i upgraded from 2.2.15), i'll try it out later after work and see if i have the same issue as you.

Great. Thanks for checking it out. I could be wrong here, but I expect this actually doesn't have anything to do with the receiver (a PTV3000 in these cases), but rather a limitation of android that means we're locked to sending audio only through WiDi when it's turned on.
It wold also be great to hear from anyone who's got WiDi working with any other receiver to check if this assumption is true.

yep, the audio is only sent via the widi. there is no sound from the phone speaker.

Alright, then is anyone out there aware of a way to override the audio output so that it doesn't get forced through WiDi? I find it hard to believe that where's no way to hear sound if connected display doesn't support audio via HDMI.

hmm Im having the exact opposite issue. Wireless display streams fine to my TV over the PTV3000, but there is no audio output to TV everything just comes out the phones speakers

Why no one seems to be annoyed by this bright spot in the right of the screen??
It is only noticeable in bright colored backgrounds (white, light blue etc), but it completely goes away on dark backgrounds and you cant notice it at all.

I ve seen this issue on every device i ever hold in my hands (demo display devices o9n stores), including my own.
I have started a thread about this some days ago : http://forum.xda-developers.com/showthread.php?t=1077527&highlight=light+bleeding , but there seems to be only few ppl worried about this..
So i wonder, does everyone else suck it up and live with it?? Maybe you havent noticed it yet?? Maybe its not so bad on your device ?? Maybe you dont have it at all ??
As far as i m concerned it really pisses me off when i look at this spot on a white background !!!
Sony DR-BT100CX Bluetooth headphones working great, incl. player controls (pause/play, FF, RW). I haven't tried the headset's microphone, but suspect it might not work yet based the user manual:
user manual said:
Note: Only A2DP stereo headsets (without microphone) are supported.
Please check for updates to the tablet's software which may add support for

The Palm Wireless Keyboard (3245WW) works perfectly. Saw no reason to buy a different one when I had this one laying around collecting dust. You can still find them used and a rare few that are new. I'm pretty sure this is just a Think Outside keyboard with the Palm brand on it.
I have also gotten the Wii Remote working well with a Nintendo 64 emulator. I'm using WiiMote Control and N64oid.
I'll be following this thread because I'm looking to get some wireless headphones.

Targus Bluetooth keyboard for iPad
So far, I'm liking this keyboard. A few of the buttons are marked a bit oddly for Android, but overall, I really just wanted the basics. A few of the specialty keys work well - magnifier bring up search, volume keys work, arrows scroll and pan...
So, yeah..not too bad and pretty low profile as well. Operates off two AAA batteries Paired very easily. Occasionally after a long period of not being used, I have to turn it off and on again, but it reconnects Very Quickly.
Very Happy until the next one that's perfect comes along.

Justop K9B stick MK809 ii

Hi, my first post so be gentle!
Does anyone have one of these, it is the Bluetooth version of the MK809 ii and although I'm generally happy with it, it does have a few shortfalls. I am using it with a lan adaptor which works well.
I have a webcam that sort of works with Skype, but the large (Skype caller) and small (local webcam) images are the wrong way round, so if anyone calls I have to squint at the tiny picture! I tried the version off xda but it's the same. Any help there would be appreciated.
I've never dabbled with flashing anything android but should I be looking at doing this perhaps, and if so I have not seen any mention of the Bluetooth version of the MK809ii. I'll probably turn it into a vegetable anyway!
I welcome any thoughts/experience with this gadget.
Cheers

which lan adapter are you using and how much.
I am looking to buy the mk809ii, and was wondering what are some CONs and disadvantage you are seeing now? I heard it is much better than the mk808 as it has less glitches?

I'm using the BOBJGEAR usb to Lan android adapter, works fine out of the box on my tv stick.
Aside from the Skype problem above (REALLY annoying!), not too many cons to be honest, just minor niggles mainly with some apps not being suited to it.
-Youtube seems to have lost its ability to go full screen for some reason, works fine on my Nexus 7 and is the same version.
-I have tried a few DLNA media apps to try and view pictures, videos etc from my NAS and they appear to be occasionally laggy across my network, the media app that came with the stick seems to work the best but looks pants!
-Watching films is generally a good experience, but the rendering isn't fantastic on darker films, probably mainly due to the quality of videos I have. Youtube HD videos are perfect.
-Google earth works but there doesn't seem to be any zoom buttons so is useless, i haven't looked into that yet.
All in all i'm happy with it, I bought a Xenta bluetooth keyboard with built in mouse which connects fine directly with the built in bluetooth. The mouse is a bit frustrating though so will be buying a bluetooth mouse.
Hope that helps
hi sadsplace, im just thinking of buying one, are you still happy 2 weeks in, any new suggestions?
thanks

No Skype calls on new MK 809 II
I just got this new TV stick which seems to be working fine. Still, I'm unable to make calls in Skype. I attached a USB webcam and I also paired a bluetooth headset, I enabled video calls in Skype, but when I get to call anyone, after 2 or 3 rings, the call fails no matter if the other party answered or not. The only error message I see is "Call failed".
If anyone experienced this, is there a way to at least see if the webcam and the BT microphone are correctly installed? I tried several webcam apps from Google Play just to get an immage on my screen and finally I got one, but not in Skype.. .

Bluetooth streaming audio stuttering persists in Android 4.3

Hi fellow xda'ers
I got the 4.3 OTA today for my Nexus 4 and the problem of stuttering bluetooth audio persists for me.
This is in reference to the bug described here: http://code.google.com/p/android/issues/detail?id=39633
I also unpaired my phone and re-paired it but still facing the same problem.
So, just wanted to ask around...
1. Is anyone still facing this same bluetooth audio bug like me in Android 4.3?
2. Can anyone who had this bug in 4.2.2 confirm that it got resolved for them in Android 4.3?
Thanks..

I am using my phone with a Clarion car stereo.
The issue now is much rarer than it was before.
I guess I need to test it out for a few more days.
Thanks..
Worked fine for me in 4.2.2 .... now in 4.3 LOTS of stutter and occasional drops. Very annoying and probably related to the change of Bluetooth in 4.3 ... hope someone comes up with a fix, otherwise I'll need to go back to 4.2.2 as I use Bluetooth for music lots. Anyone that can help ... ??
I was excited to see that as soon as I upgraded from 4.2.2 to 4.3 my bluetooth streaming worked flawlessly in my car for a 2 hour drive into the mountains. However, a couple days later the stuttering came back, just as you described.
This was the one thing I was looking forward to for 4.3 but it looks like we've been let down.

I'm not really sure, what's happening.
I tried earlier on with Poweramp Player (third party app) and Google Play Music, I had stuttering in both the apps.
Then I decided to unpair the phone/stereo, change the phone name and then re-pair. Just wanted a fresh start..
After that, I had the stuttering problem whenever I used Poweramp player. The problem happens within 5-7 min. However, when I use Google Play Music, it seems to work fine. However, I haven't tested it for long. Maybe 1 hour max, so can't say if my hypothesis is correct but I'm keeping my fingers crossed. After 7 months with this phone, I really need to get Bluetooth working.

I'm in the same boat. But I really am wondering if looking at the software/apps used is the wrong method. I've been doing the same thing. Over the past 7 months I've tried various ROMs, kernels, radios etc. and nothing changes it. I've talked about it with various friends with Nexus 4's and none of them seem to have any issues.
At this point my money is on the Clarion stereo being the issue but I still have not tested the phone with another stereo. This weekend we are visiting my parents. I will try using the phone with the bluetooth on my Mom's 2013 4Runner and my Dad's 2010 F150 to see if I can replicate the problem. If it works with both their cars then I will be in the market for a new stereo. :laugh:

At the same time have you checked the reverse? Any other phones that work fine with your stereo?
I have and I can say all other phones have worked fine with my Clarion stereo.
If N4 continues to have problems with the Clarion stereo, it could be easier for me to sell the N4 and get another phone, unfortunately a non-Nexus one

It seems the problem is with our Clarion car stereo indeed. A lot of Clarion stereos have bluetooth issues:
http://www.fixya.com/support/t12082313-bluetooth_audio_streaming_breaks_up
http://community.crutchfield.com/car_audio_and_video/f/27/receivers/t/22006/clarion-cx501-bluetooth
Phones like iPhone 4, Lumia 920 and Moto Razr also seem to have these problems.
My stereo CX501 doesn't have any bluetooth firmware upgrade too. Though, they have provided some firmware update for some other stereos like NX501 and so on. So you should check out on their site for a firmware upgrade.
http://www.clarion.com/us/en/support/compatibility/bluetooth/index.html
I really think you're right. I tried streaming music through my girlfriend's car stereo last night and had absolutely no issues. I've also read the threads you linked to as well as a few others and the consensus is that Clarion keeps trying to pin the blame on the phones and not their receivers. Looks like it's time to change stereos...

You should at least check if there is a firmware upgrade available for you on Clarion's support site before spending on a new stereo.
Unfortunately, it's not available for my stereo CX501.
I have stuttering too on both my A2DP devices. Both are cheap: one is from DX, th eother is from a local 'dollar store' (where it was 10 euro or so).
The one from the dollar store seems to work fine after pairing, but not when connecting again.
The one from DX (z nice plug for the aux in of the car, with a mic and henadsfree speakers through the car audio) seems to stop stuttering after a few minutes. The audio level is a lot better with 4.3.
But no difference in stuttering beween 4.2.2 and 4.3.
Problems remain
I have found no improvement with my Nexus 7 with Android 4.3. I get stuttering every minute or so. I've done a bit of reading and found that Bluetooth is hellishly complex - and would be very difficult to debug. For instance to set up audio streaming, both devices need to agree on a codec to use. There is a default base level codec. As I have found that the issue is worse on some bluetooth receivers than others, I can only guess that the issue relates to Android's selection of a codec or other parameter on some devices. I certainly have no issue with any device streaming from my windows laptop (no matter how busy it is).
I have the exact same issues with bluetooth stuttering.
Using 4.2.2 PACman rom on my Note 2 with a Sony MW600 bluetooth adapter, the audio would switch off for a second every minute or so, whether using Google Play music or PowerAmp, but it seemed to happen less on the former.
Updating to 4.3 has made it worse, the audio now switches off for at least 5 seconds to the point where i have to check if the phone or app has crashed each time.
I never had an issue with the Revolution HD rom (I think its called?) but I believe that's mostly stock?
It kinda feels like the bluetooth can't handle the bandwidth depending on the size of the file. I think there's less stuttering on lower quality files - could just be in my head though.
I have a Galaxy S3 i747 running latest 4.3 CM10 rom. My audio stuttering actually got worse when upgrading from 4.2.2. Using platronics 903+ and a bluetooth stereo unit for my motorycle helmet.
Very disappointed. My work iPhone doesnt skip a beat.

Android 4.3 Bluetooth Audio Quality Fix for Nexus 7 Flo

cbaronne has posted a set of compiled binaries to change the default bitrate of the Bluetooth SBC codec to increase A2DP audio quality on the Nexus 4 over on this thread. It seems that the 2013 Nexus 7 suffers from the same issues, but can also be fixed with the same binaries.
I've very lightly modified itlnstln's update script to work on the Nexus 7 and have tested these files as flashable under TWRP. The binaries in the flo-4.3-BTFix-googledefault.zip file are from the ParanoidAndroid 3.94 ROM (which I would highly recommend) should you experience troubles with your Bluetooth devices.
I would recommend trying the 328kbps version first, and would expect it to provide the best quality in most situations since it matches the sampling rate of most MP3 files. Most Bluetooth stacks for other devices have 328 as the maximum quality. Of course, test with your devices and ears.
For device testing, I've used it to great success with a BlackBerry Music Gateway (still stuck at low volume, but that's an AVRCP volume control issue) and a Philips AEA2000/37 Bluetooth receiver. I also have an eBay/Chinese receiver which identifies itself as DMZmusic where this change causes continuous popping noises from both my Nexus 4 and Nexus 7. That device is perfectly fine when paired with my other devices that stream at full quality with A2DP SBC (BlackBerry Playbook, WP7 phone, and Windows PC using the Toshiba stack), so clearly Google still has some work to do. Until then, hopefully these files prove to be useful.

Yes, just flash with TWRP. Note that this only affects A2DP Bluetooth audio (ie: wireless headphones and stereo receivers) in situations where it sounds like Internet radio from the year 2001 and won't do a thing for the static noise when using the onboard speakers at low volume.
328K did seem to help with Netflix + BT but it certainly wasnt perfect. Its rather disappointing that such a powerful tablet cant even BT + netflix properly.
Thanks much for sharing.
Aren't any Android Tablets/Phones out there which support BT-MP3/AAC Codec? Maybe those can be ported to Nexus devices?

I don't think you can blame the Nexus 7. I reverted to the previous version of the netflix app and the audio is fine. It appears netflix broke something with the latest update.

I don't know if this is related to the problem of BT keyboards working properly (interference on the 2.4 Ghz band between WiFi and BT), but if it is, would you know how to fix that problem as well? Only reason I ask is that I was under the impression that BT audio also suffered from the interference issue, and would especially make sense if paired up with netflix streaming (which would be sending data over WiFi simultaneously).

I haven't dealt with that issue specifically on the Nexus 7, but I have had nothing but terrible luck with most Bluetooth HID devices for PCs and now just recommend using sets from Logitech or Microsoft with proprietary RF USB dongles. Apple's devices tend to work OK though. As for interference, I have no trouble streaming BT audio while also pulling HD video over my 2.4GHz WLAN, but then again I'm not in a very RF saturated area and also have automatic channel hopping disabled on my WiFi AP. If you're in a highrise or something like that, the only possible solution is going to be to get your WLAN onto 5.8GHz to try and free up some spectrum.
I don't think I've heard of any Android devices that do MP3 or AAC BT audio, but there are quite a few that can do AptX. As far as I know, only the manufacturer ROMs provide the codecs for this (ie: flashing CyanogenMod to an SGSIII will kill AptX), and receiver compatibility is pretty low. It's a shame that there are so many cooks in the Bluetooth kitchen that we end up with this metaphorical beef and Cheetos stew.

I don't think you can blame the Nexus 7. I reverted to the previous version of the netflix app and the audio is fine. It appears netflix broke something with the latest update.

Thanks posting your fix. I just reverted to a previous version of netflix and now I have absolutely no audio issues over bluetooth.

:good: Huge thank you to OP. Ever since I got my nexus 4, it always had crappy bluetooth audio playback. For a while I wondered if my speakers in the car were damaged also but I tried your fixed and it worked flawlessly. Crystal clear and rich sound now. This is confirmed working on the latest stock nexus 4 jwr66y

You know, I downloaded a Beats Audio APK and that did the trick. Just google BeatsAudio07.02.zip and the first link will where you can download it. I noticed a big difference on my N7 I use at home and definitely the N7 I have installed in my car. The sound thru my Infinity System sounds like crap. Once I downloaded and flashed this zip, it was a huge improvement. :good:
Just got a netflix update last night (3.0.1 build 1016,) fixes the bt issues I had with it =]
Can't update
Does anyone have the default audio.a2dp.default.so, after applying this fix I can no longer OTA.

Error: Unfortunately, Bluetooth share has stopped
Hi Guys, I'm new to N7 and first thing I wanted to do is to upgrade BT audio q. After causing endless bootloop (X), I had to restore device to factory settings using Nexus Root Toolkit v 1.7.8 and loading Android 4.4.0 - Build: KRT16S. Only after that, I tried again to flash "flo-4.3-BTFix-328kbps-2013-08-18.zip" and everything looked ok until boot when there was a pop up message with an error: "Unfortunately, Bluetooth share has stopped". Same with other zip (345kbps). Any idea where might be the problem?
EDIT: Obviously I was trying to use 4.3 fix for 4.4. build When I realized it, I loaded again 4.3 system, flashed zip and seems to be ok now!
So anyway @random_n, could you please update this fix so it would work for 4.4 as well. It would be greatly appreciated!
Has anyone found a kitkat audio fix yet? I justvtried my BT headphones with my n7, and the sound is ungodly bad compared to my galaxy s3.
Since the tablet gets longer battery life, I'd prefer to use it for my wireless audio instead of the s3.

Miracast / Screen Mirroring Feature

Hello everyone,
How is your opinion about the Z1´s Miracast (aka Screen Mirroring) feature?
After a few testing I must say that i am a bit disappointed.
Its not the lag (kind of natural for the current state of Miracast) that makes me say this, but the lack of a stable connection.
It works great for viewing static content like pictures, but fails when sending a stream, e.g. music or videos. This mostly results in stutters, bad sound / video quality or even a loss of connection.
P.S.: I am using Netgears ptv3000 as receiver, which works great with my laptop.
best regards.
MicroSoft Miracast Problems
I too am disappointed with the Miracast implementation on my Z1.
I have updated to the latest version of 4.4.4 and I tried to set up the Microsoft Display adapter (Miracast) with the Z1 and it fails due to HDCP support issues.
Apparently Sony is so paranoid that they block the Z1 from talking to anything that is not fully HDCP 2.2 compliant. Really, I bought your phone, and the people that want to steal your content can already do it, with our without your HDCP limits. All that Sony is doing is making it hard on their own customers.
OK, put a block on the Walkman app or the movie app if you need but I just want to project my screen into my car's AppRadio.
I can use MHL ... no problem but I don't like having to open and close the USB port every time I get into or out of my car. I want to use the magnetic charger for power and the wireless Miracast to sent images to the AppRadio.
Apparently the problem is that Microsoft is not 2.2, but really this is Sony trying to hold the Keys too tight.
Just like apple did with iTunes. Look what happened there. The DMR made it a hassel so people got free music of the web. Once Apple opened up the access and removed DMR then people were able to listen their way and iTune sales jumped.
Are you listening Sony ...
Apparently Sony has said they will fix this in Lollipop but I don't have 5.0 yet, I need a fix now.
Does anyone have any suggestions on how to turn the HDCP restrictions off on my otherwise stock (but rooted) Z1
Thanks,
C
miracast worked fine with my tv until kitkat, jellybean worked fine
Screen mirroring is great for me, using sony bravia tv wifi direct, no lag and great picture quality.
