What `model` option values are available depends on the codec chip.
Check your codec chip from the codec proc file (see "Codec Proc-File"
section below). It will show the vendor/product name of your codec
chip. Then, see Documentation/sound/alsa/HD-Audio-Modelstxt file,
chip. Then, see Documentation/sound/alsa/HD-Audio-Models.txt file,
the section of HD-audio driver. You can find a list of codecs
and `model` options belonging to each codec. For example, for Realtek
ALC262 codec chip, pass `model=ultra` for devices that are compatible
@ -177,7 +177,7 @@ with Samsung Q1 Ultra.
Thus, the first thing you can do for any brand-new, unsupported and
non-working HD-audio hardware is to check HD-audio codec and several
different `model` option values. If you have a luck, some of them
different `model` option values. If you have any luck, some of them
might suit with your device well.
Some codecs such as ALC880 have a special model option `model=test`.
