Public bug reported:
I have no audio output on internal speaker (headphones untested) with
HWE kernel (5.15.0-56-generic). Audio does work on GA kernel
(5.4.0-135-generic).
It appears that due to UBSAN striking against intel-sof, the codec is
not loaded properly during boot - but I may be misinterpreting this.
Kernel tainted due to wl.
