It looks like it is going to be fixed upstream:
https://bugzilla.kernel.org/show_bug.cgi?id=106961

...but from alsa-info attachment (here on launchpad), I can see that the
fix may not work for your PC. The subsystem ID is slightly different.
Mine is 0x103c1473, yours is 0x103c146f. Please try the proposed patch
from bugzilla comments (link above). If it doesn't work, try the
proposed patch with your value 0x103c146f and if this works, report it
to the bugzilla.kernel.org so the upstream fix will work for you, too.
