Phoronix: Intel Lands Linux Audio Fix For Intel Arc Graphics A750/A770

If you have been running a Linux 6.3-based kernel or later Linux 6.2 point release and have encountered your HDMI audio breaking when making use of Intel Arc Graphics A750/A770 hardware, a fix is on the way...

I don't think this is the best way to solve it, but I guess the real issue is in the device firmware, and that's much more complex

nice "fix"
lol
i wonder if the reciever will display some message every time the sound stream is turned off

[Shtirlic]

I don't get it, why it's not possible to prepend silent samples before new stream starts? Some delay - sure, much better than lost sound.

Well No KEA then.

Boy, this was one confusingly explained problem or written article. Anyways, not a fan of HDMI, but do have the following already within my modprobe settings:

$ cat /etc/modprobe.d/alsa.conf
options snd-hda-codec-hdmi enable_silent_stream=0

The enable_silent_stream=0 option was needed for my Intel A750, for recovering playing a stream's audio after switching displays. Otherwise, after switching active displays with using a mouse (or keyboard), the stream (eg. video playback) would loose audio/sound. (I forget the exact description of the problem, and going from memory.)

Seem to be on kernel-6.1, so likely have avoided this problem,
