YouTube, other video will play, then freeze in a high-pitched buzz noise; UBSAN

Occurs with most recent versions of both Firefox (snap) and Chromium (snap, apt). Duration before issue occurs is under a minute to perhaps five minutes.

Syslog has multiple entries stating similar errors such as:

[ 18.349533] UBSAN: shift-out-of-bounds in /build/linux-4LEpwz/linux-5.15.0/sound/soc/soc-dapm.c:3411:13
[ 18.349539] shift exponent 16384 is too large for 32-bit type ‘unsigned int’

Updated to kernel 6.2.5 in the hope it would solve things, now says, e.g.:

[ 16.789864] UBSAN: shift-out-of-bounds in /home/kernel/COD/linux/sound/soc/soc-dapm.c:3395:15
[ 16.789868] shift exponent 16384 is too large for 32-bit type ‘unsigned int’

Is it trying to compile the SOC audio block code for some reason every time it boots?

Purging and reinstalling “firmware-sof-signed” did not fix the issue.

Could be related to your SOC.

The user also asked this on Reddit, to no avail. I offered up the only things I could think of.

I’m sure they’re open to trying things. :smiley:
