Does anyone know how to address the issue of no sound after sleep (suspend) mode on Solus 4.1? If I select suspend/sleep mode or close the laptop lid and then wake the laptop opening it again, there is no audio/sound coming through speakers. In order to have the sound coming from the speakers, I need to restart/reboot the computer. So the audio works just fine after the restart, but not after sleep mode. It's interesting that after the sleep mode, the audio DOES work but only through the headphones. I used Solus on other machines in the past but never had this problem. This is a relatively recent install on a new laptop (Xiaomi Notebook Pro i7, 10th Intel+Nvidia). I tested this issue with other distros, such as Pop_OS, Elementary OS, KaOS, Zorin, and default Ubuntu; so far, only Zorin seems to respond properly after the sleep mode. Thanks for your feedback and suggestions.

Might be a bug with pulse audio, try killing pulse audio and see if sound comes back on

Hi, I had exactly the same issue on my Lenovo L450 with built in Intel sound card Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09) - my alsa-info. I found a workaround here. You have to edit Also config file /etc/modprobe.d/alsa-base.conf (did not exist for me) and add this line options snd-hda-intel probe_mask=0x01. Not sure what it does, but it works.
