No Audio on Android TV / Android Mobile

[Joe Farmer 2]

Hi team,

Bit of a strange issue. I have a series of video's of my kids dance concert that play without audio on Android TV's and Android mobiles but the audio plays fine on my Windows PC and on iPhone. No idea what the problem could be as the audio format, as below, seems pretty standard:

Title  English AAC stereo (Default)
Language  English
Codec  AAC
Codec  Tagmp4a
Profile  LC
Layout  stereo
Channels  2 ch
Bitrate  253 kbps
Sample Rate  48,000 Hz
Default  Yes

For reference, below is the audio format of a video of a different concert where the audio does play, the only difference I see is the bitrate, could that be the problem on Android devices?

Title  English AAC stereo (Default)
Language  English
Codec  AAC
Codec Tagmp4a
Profile  LC
Layout  stereo
Channels  2 ch
Bitrate  106 kbps
Sample Rate  48,000 Hz
Default  Yes

Here is another that works fine:

Title  Und AAC stereo (Default)
Language  und
Codec  AAC
Codec  Tagmp4a
Profile  LC
Layout  stereo
Channels  2 ch
Bitrate  191 kbps
Sample Rate  44,100 Hz
Default  Yes

Ok, fixed it. Seems the problem was the bitrate. I converted the files and dropped the audio bitrate to 192 kbps and now it's working fine.
