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 that works is hard 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... logs from alsa-info when sound is working: https://pastebin.com/0CuJWiG1 When it's not working (after resume): https://pastebin.com/CGD2GDGb the logs are from when I added the following to /etc/modprobe.d/alsa-base.conf: 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 a 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. Playing anything on front-right or changing balance results in no sound. Would be grateful for any help.
