no audio when screen casting to TV

Screencasting to Tizen TV has working image, but no audio at all.
Reported by another user for LG TV.

I Have Same ISSUE!

Can you share adb logcat -b all,kernel | tizen_tv_sound.logs

@Lobanokivan11 If you don't want to publicly share, you can DM @dev-harsh1998

I'll need a few more days to find time and be in a place with tizen tv.

Command did not work:

adb logcat -b all,kernel | tizen_tv_sound.logs
zsh: command not found: tizen_tv_sound.logs

Retried with

adb logcat -b all,kernel

There is an option for Stable volume in the youtube webui. Toggling that setting does not change anything in regards to the audio issue.

Nerd stats says:
Volume / Normalized: 100% / DRC (content loudness -2,4dB)
Codecs: vp09.00.51.08 01.01.01.00 (248) / opus (251)

With nabu connected to tizen TV
12:59:00 Play youtube video in firefox
12:59:15 pause video

Is the audioserver: logFgsApiEnd: FGS Logger Transaction failed, -129 part of interest? The full log has more errors for MediaPlayer.

Let me know if this is sufficient to work with or if you need more debug info.

[dev-harsh1998]

adb logcat -b all,kernel | tee logcat_audio_tv_audio.log @foss-

@dev-harsh1998 debug log sent. Let me know if this should rather be filed with upstream or if it is indeed a device issue.
