<pre>Basically my issue reads very very similar to the one from bug id 104952.
I am running Ubuntu 18.04.1 LTS on an Gigabyte Prix GB-BLPD-5005 (Intel Pentium
J5005 Gemini Lake). Running mainline kernel:
Linux brix 4.20.5-042005-generic #201901260434 SMP Sat Jan 26 09:36:17 UTC 2019
x86_64 x86_64 x86_64 GNU/Linux
I have attached a Yamaha AVR via HDMI and after that a Samsung TV:
Whenever I switch off the AVR and turn it back on after some longer time (> 60
seconds or a couple of minutes - not tested that much yet) - I loos HDMI audio
and have the following messages in dmesg:
[52092.976001] snd_hda_intel 0000:00:0e.0: azx_get_response timeout, switching
to polling mode: last cmd=0x20bf8100
[52093.983688] snd_hda_intel 0000:00:0e.0: No response from codec, disabling
MSI: last cmd=0x20bf8100
[52094.988008] snd_hda_intel 0000:00:0e.0: azx_get_response timeout, switching
to single_cmd mode: last cmd=0x20bf8100
[52095.272444] snd_hda_codec_hdmi hdaudioC0D2: Unable to sync register
0x2f0d00. -5
For getting HDMI audio restored I need to shutdown X and unload/reload
snd-hda-intel.
Please advice what kind of debug logs are needed for investigation and I will
happily provide them.</pre>
