I had this happen again about a week ago, though it happens very rarely
now.

Title:
Sound w/SOF driver sporadically fails
Now that the new SOF firmware is included in the linux-firmware package
(see bug #1900809) the audio stack has been much more stable for me.
Unfortunately there has been still one audio stack crash after the
firmware upgrade, but it probably was another issue, since the dmesg
didn't contain
Status changed to 'Confirmed' because the bug affects multiple users.
** Changed in: linux-firmware (Ubuntu)
Status: New => Confirmed

It seems that the 1.6 version of the SOF firmware fixes the issue for
me. Haven't got any of those DSP panic messages anymore after the update
and before the update they occurred almost every day.
Is there anything I can do to help in making this fix to be included to
linux-firmware package?
If this is indeed the same issue as in
https://github.com/thesofproject/sof/issues/2828, then the problem
should be fixed by upgrading the SOF firmware to 1.6 version.
I'll give it a try by installing directly from
https://github.com/thesofproject/sof-bin/tree/stable-v1.6
I will let you know if
I have the same problem with Lenovo T14 (Gen 1), which seems to have a
similar sound device:
