My laptop HP ZBook Fury 15 G7 Mobile Workstation has the problem that there's no sound after I suspend and resume it. The only solution I found so far is reboot.
I have 2 cards on my laptop, one is
HDA Nvidia controlled by
snd_hda_intel driver and the other is
sof-hda-dsp controlled by
snd_soc_skl_hda_dsp driver. Not sure about Nvidia card - didn't use it so far, but the problem is with the latter, which is my "main" sound card labeled
Realtek ALC285. Sound works fine until I suspend and resume the laptop and nothing in the log seem to point to the cause of the problem...
alsa-info when sound is working:
When it's not working (after resume): https://pastebin.com/CGD2GDGb
the logs are from when I added the following to
options snd slots=snd_soc_skl_hda_dsp options snd_soc_skl_hda_dsp index=0 options snd-hda-intel index=1
Think I tried most solutions I could find on the net. Re-inserting
snd_soc_skl_hda_dsp hangs forever. I also had this problem with
pulseaudio being started by
gdm, I stopped it but it didn't make any difference so not sure how important it is.
Another strange thing is that although the sound card is reported as 2 channel, it seems like the
front-left channel is the only one that works, but all speakers are playing as if it was one giant mono speaker only. Playing anything on
front-right or changing balance results in no sound.
Would be grateful for any help, it's really hard to work if I have to restart the laptop each time I suspend it. Thanks!
