ALC268 codec shipped with Toshiba Satellite X200 has ids 1179:ff00 and began to match quirk table.

If it doesn't match and auto-probe from BIOS is used, alsamixer works:

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.

thanks,
