[SOLVED] intel audio: no soundcards found, hardware issue? [<- yep]

After an upgrade and reboot last night, my onboard Intel soundcard on my MSI laptop is no longer found. I've already tried downgrading the entire system to the state before the upgrade and then rebooting to no avail.

Relevant info:

The laptop is 1-2 years old and this is the first issue with sound that I've had. However, I have had other issues which may indicate a general hardware problem. Sometimes when trying to wake the laptop from sleep, the screen remains off and the capslock led starts blinking. The magic sysrq key is ignored in this state (the IO led never lights up) so I thought it was a random keyboard error. The only way to recover is with a forced reboot. When rebooting after the freeze, the keyboard is sometimes inactive until the kernel boots (e.g. key presses are not registered for the bios password, although plugging in a usb keyboard always works). After the reboot, there are no issues with the keyboard.

My current suspicion is that the card or something else just died but I haven't given up hope yet. Any suggestion of what to check or test would be appreciated.

I've had issues with other systems in the past that were solved by simply leaving them fully powered off for a while. I plan to try that as well, but the battery pack is integrated in such a way that I have to disassemble the case to remove it. I've already lost a few bits of cheap plastic that last time that I took it apart, so I'm leaving this option as a last resort.

Re: [SOLVED] intel audio: no soundcards found, hardware issue? [<- yep]

All of these snd_sof modules read like its running into the DSP detection bug that has plagued a few people on 5.5/5.4 kernels.  See this thread/post for example but unlike the dmesg of the OP in that thread you don't have the obvious call backs to the DSP logic so that doesn't make me completely sure it's the same issue.

Googling for that message also doesn't really turn up much conclusive other than trying a BIOS/UEFI update, so if this indeed happened that suddenly I'm also leading to maybe some HW issue.

Thanks V1del. How do I test the options suggested in that thread? I haven't been able to find how to reload asound.conf? Is it reloaded when the modules are reloaded? I've tried that but without success.

The one I'm talking about is a kernel module/modprobe option, afaik you can't really reliably reload those and a reboot would be safest.

If this were just an asound.conf issue "reloading" happens whenever you invoke something that uses ALSA.

It indeed seems to be a hardware issue. I left the laptop unplugged and powered off all night (with the battery still connected). Lo and behold, the sound card is back today.
