No sound from certain apps - Android Head-Units

I have a 10.25 android unit in my mercedes running android 9. I have a weird issue where I have no sound from certain apps.
Google chrome app no sound when using youtube in browser but have sound using youtube app.
Amazon music - no sound
soundcloud - no sound
But then I can use spotify with no issues.
I have tried uninstalling and installing the apps with no success.
Anyone else come across this issue and knows of a resolution?

Try rechecking your ground wire. Make sure it is connected properly.

I was thinking more along the lines of a codec issue. Based on the fact I do get sound from other apps?

a bad GND can cause all sorts of strange issues, even on the software side of your unit..
that said, android handles sound in a strange way, and sometimes it can result in silent apps.
basically android can not mix sounds from impended apps/sources. it grants permissions and checks which permission overrules a previous permission.
if a app does not ask for audio permissions and invokes them straight away, another app or the previous app could hold the audio permission, thus muting the app you are using.
so if you start chrome for instance it does not ask for audio permission on startup and can get muted.
you can try to dive deep in the apps permissions to give them audio permission manually, so the app can give audio again.
but it could happen (with older andriod versions) that if another app uses audio like your navi voice directions, or you speeding camera app, chrome would not get audio permissions back until restart.

After a CLEAN nougat update.. music no longer pauses with dictation HELP!!

Okay,
To recap, im not a novice i've been on these forums since my S3! :good:
Moving on..
Before when I had marshmallow when ever I listened to streaming music ORSaved mp3 collection on my SD card. I could be driving down the road and listening to my music then a text would come in and I would push the MIC button on the samsung keyboard and it would always pause while I dictated, then resume playing or streaming!
https://www.youtube.com/watch?v=X95qtx1vPMI This is my video to show what I mean.
Since this new nougat update, Plain and Simply.... I CANT! Not just Bluetooth, the phone speaker too!
I use Spotify and Poweramp to listen or stream.
Using the process of elimination i tried the following...
1) Complete Factory Reset.
2) Changing and resetting permissions to the keyboard app and the music apps.
3) Installing a different keyboard app ( Swiftkeyboard )
4) Safe mode reboot and test..failed.
5) Wiping the CACHE partition.
6) Clearing Data on Samsung Keyboard App.
GET THIS!
If using the Google Assistant to dictate, the permissions grant it to pause any app that is outputting sound.
I've called verizon, THEY ARE DUMBFOUNDED.
I've Tried Samsung+ Live tech support.. They are escalating it!
HELP IF YOU CAN!
my thoughts are..
1) the samsung keyboard app doesn't have high enough permissions to keep the music paused.
2) the update has a bug in the keyboard app.
3) Google assistant will not allow the keyboard app to put a hold on it.

Problem with video & audio

Hello,
I started having some strange issues with audio and video playback on my Nexus 6P. It seems that my phone has suddenly lost the ability to play any audio or video file. In Google Photos app if I try to play a local video file it just informs that the file cannot be played. If I try to shoot video using Google Camera it just informs that the connection to the camera is lost. I cannot listen to Google Music or even the system ringtones & notifications. Even the alarm clock starts without any sound(only vibration).
I don't know what exactly caused this. My phone is rooted and I'm using custom roms. Lately I've been using Pure Nexus and Substratum themes. I suspect that the problem started after switching the theme in Substratum.
I have already wiped my phone from recorery(TWRP) and clean installed the rom & gapps. That didn't seem to help so I clean installed another rom(Nitrogen OS). I still seem to have the same issue.
Could this be hardware related issue? Any ideas?

Sound issue with Chrome taking sound priority

Using a no name Android 6 head unit I have been suffering from the following issue:
Trying to play media in Chrome, in websites like YouTube for example, I hear no sound from chrome and the sound is still coming from the Radio app.
The desired behavior is that Chrome will take control of the system's sound while playing the video. This happens correctly when I open the YouTube or spotify app for example: While playing a video or a song, the sound is coming from the app and when the video ends, the radio is heard again.
I have other apps which much like Chrome fail to take control of the head unit sound.
Any suggestions?
Thanks a lot in advance

Bluetooth Media player App (for Headunit)

Hi all,
I have installed an Android 7.1 headunit in a car, I have replaced most of the default apps, but one I am struggling with is the Bluetooth media app. The Default app on the HU allows me to play music from my phone, but it has only 3 buttons on it, play/pause, forward and back, it doesn't give any track information, or have any visual indication that music is even playing, the device does support A2DP (and so does the phone).
I thought it would be very easy to find a media player that does this, but it seems not, now I realised, this app is very rare, its not usual for an android app to be receiving the stream, normally it would only send the stream. So wondering if anyone has found an app that can do it?
Also has anyone else ever replaced the default FM radio app on a headunit? I believe its not possible because its customised to the specific hardware but I am interested to look for an alternative to this aswell (current one has a bad interface and doesn't save stations if power is lost)

Also looking for this! anyone?
Bluetooth App
I completely agree. I just got an 8.0 head unit from Pumpkin ( px5). The BlueTooth App seems pretty basic:
1) sound quality is noticeably lower
2) app is buggy -- after a call, which was ended, the green call icon stayed in the lower right corner until I did a reset of the unit
3) no info about what is being streamed
4) UI of the app is really plain - not much color, etc.
Is this open source somewhere?
Same question here....
Waiting also!!

BEST audio player for ANDROID head units

Greets all!
I've just joined the Android Head Unit community with the installation of the ATOTO A6 (A6Y2721PB).
So far I love it with the exception of a few minor gripes.
The audio player that comes with it has terrible sort functions. OR basically non-existent sort functions. It categorizes (very badly) the music library into a few categories (Singers, Songs, albums, folders) and all poorly and inaccurately. If there was some useful sort functions under FOLDERS; this wouldn't be so bad, but there is not. It will not even sort alphabetically. It will sort by the number of tracks that is in each folder. That is worthless!
So I'm looking for a better player. I really don't care about STREAMING services support. It comes with Spotify and Pandora already and I don't use them. I'm interested in playing my 1000+ track music archive in the FLAC format. BUT I have to have adequate sort functions. Most all of my archive was not CD rips that does the CDDB encoding. I backed up all my original collection into WAV files a decade ago and that is the source. The only think I miss is the album art. The easy way is to have the album art store in each folder entitled folder.jpg. Many players will display that many don't recognize it. Also I need the player to support widgets so I can integrate the player into the home screen.
I've tried Foobar2000 and like the functionality but it is UGLY with only B&W menus and it does not support widgets. I'm going to try VLC but not sure it will handle music files as well as it does video.
Any suggestions out there?

There are many, many Android music players out there.... While opinions may differ based on users' experience, there's really only one that stands out for the use in a HU: PowerAMP . For me it's the player that has everything and is fully integrated in the Android system:
Great Audio ducking
Configurable widgets
Support for folders (and folder.jpg)
If not present, album art download
Has its own audio engine
Support for almost every car launcher
Beautiful album art support
and many more...
It takes some time to configure it the way you want to (don't need the visualizer for instance), but (almost) everything can be adjusted.
But to get the most out of if (that goes for every player), be sure to have your music properly tagged
I've got an old video on YouTube showing some PowerAmp footage https://www.youtube.com/watch?v=AT0ewLZ8mOc

That's nice, but would not it be better if it have a integrated DSP chip in combination with poweramp?

Great, this is what I was looking for. I see the paid version is only about 4 bux. I'll try it and see if it does what it needs to. I'm ready to uninstall the player than came with the unit. Nothing but frustration.

Well it all depends on your speakers off course and I don't have a DSP. But I can tell you that on the Head Unit I have, the original sound was ok. After using and enabling PowerAmp's own engine and equalizer, sound was far, far better.
However, using Viper4Android (if you're HU is rooted) takes the sound to another level. I didn't even know my stock car speakers could produce such rich basses... I guess having a DSP would give you similar results.
Well gentleman,
I installed PowerAmp and paid the 4 bux for the full version.
Overall I really like it's feature and silky smooth operation. The issue I have is that the sound output level is about HALF of the other audio apps. This is a big problem since I have to turn the volume up much more to hear it's playback. I went under the audio tab and made different changes to the setting trying to get more output from it but no dice.
I'm going to email the developer on the issue. But otherwise this one is a keeper, I really like it's functionality.
BTW, The Atoto A6 does have it's own DSP chip for audio processing.

PowerAmp has a separate master volume control. Have you tried that? Also the equalizer has a master gain.

Yeah, I got on the PowerAmp site and looked through their FAQ page. It recommended turning DVC off if you have volume problems.
I'll try that after work today.
ive been using Power Amp for a while on my android head unit. It is the best of the bunch. The latest update has created issues playing music so until a new stable release was offered, I tried a few others and the rest are just okay. VLC was actually pretty good but I found that most of the players won't pass audio file text to the home screen widget and won't display my album art. So I am back to power amp. the dev has sent me a link to an alpha build that should fix my issue. I have just been too lazy to install it.
I got the widget working and was able to turn off the DVC function. The volume level is back to normal now so I'm really loving PowerAmp. It has features I really don't need or want but at least I can turn them off so they won't cause havoc unlike the other players I tried.
As far as the DVC function it seemed like a good thing but it just cut the sound output way too low. Reading on the PowerAmp site it stated that incompatibility with DVC will cause this. I'm wondering that this means. This unit (Atoto A6) has it's own DSP for audio affects like EQ etc. I'm wondering if that is the issue.
I also have a forward facing camera for the DVR and a backup camera. Plus various part to make all the USB connections accessible to the passenger compartment. I planned to install all that this weekend. Well didn't happen. The washing machine blew up and we ended up in town all day shopping for a replacement. Will get to it soon.
Hi. My problem with poweramp is that when someone calls me my headunit stops playing music and i am answering the call. But 1 second later music starts plwying again and i can not hear the caller and he cant hear me cause of the music...

GMMP is the best pick if you have a large music collection. I have 40k+ tracks on a mechanical HD on my head unit. GMMP will play through them no problem with an initial delay of about 30 seconds for the scan to get going. Poweramp craps itself and hangs for long periods of time (up to 60 minutes) while it scans/updates it's library. And then takes about 20-30 seconds to skip a track.
So my votes:
Small music collection, go for Poweramp.
Large music collection, go for GMMP.
I probably tried more than 20 apps, in the end it was Neutron that gave me the best results, I play only flac and have like 240 GB of them in my car, it works really flawless but you need to take the time to adapt it to your likes since really everything can be configured
http://neutronmp.com/
I've been using this for about 5 months, it's nice.. only thing bad is, it doesn't like to start in the SD card folder after starting up after being shutoff, so I have to manually browse to the SD card fold every time I start my truck..
It seems as all the dsp features do work.. there's a million things and settings in this paid app, seems to get updated regularly.. I wish it would leave the track list on screen all the time if wanted

Wow;
Not had that issue. What ever is playing it all mutes until the phone call is done on my ATOTO.
There are a ton of setting for everything in Power amp. Look through the settings and see if you can find a mute on call feature.
Have anyone been able to get an ipod to play through any app?

just tried this app, having similar issue. I think for me at least it gets totally confused when I plug in or disconnect another UDB drive. It seems as tho my HU(IDoing) shifts the USB volumes and neutron loses it's library. Otherwise the app seems near perfect.
