ALC4080 BLOCK SCHEME

I found simple documentation about ALC4080 and block scheme show that it has hardware boost with 4 possible cases - +0db,+10db,+20db and +30db

Here this scheme https://www.igorslab.de/en/the-old-alc4080-on-the-new-intel-boards-demystified-and-the-differences-from-alc1220-insider/

Here my alsa-info log http://alsa-project.org/db/?f=b8bbd4bd74e59d83d109b768e4d3e5e1bc8b8c81

Also if you look at this block scheme you will see that after ADC we can see Volume control that has control range from -17 to +12db - and only this part controlled by Linux/ALSA.


Expected way to able control boost block to specify boost value or at least boost it by default by driver.

Sorry if I something missed (it my first bug report here) - if you will need some additional information please ask.

Looks like very similar bug https://bugzilla.kernel.org/show_bug.cgi?id=217786 but here reported for only one mobo - but this issue is global I think
