Well, it's no right fix.  The symptom implies that something wrong
with the current model=toshiba, so fixing the quirk is the way to go
at this moment.

Could you give alsa-info.sh output (run with --no-upload option)
as vanilla kernel?  Run with both model=auto and without model option
and attach both results to compare.  The former means actually the
condition as your patch does.
