They control amplification of sound that enters input lines. 0 means just pass it as is
I rarely increase them

this should be enabled, if you want to record from device:

from my expirence (I also own STAC9227 btw), this is normal, and I even set this to 100%

It looks like what you have now, is exactly what I always had
Maybe hardware is capable of louder sound, although I have studied the datasheet, and I havent seen that

Can you tell me exact version of kernel that allowed you to set higher volume,
and can you test whenever you actually can set louder volumes on that kernel, maybe it has a bug

Btw, I have sent quite a lot of patches for this driver, for example, you will have 'Master Volume' control,
and you will be able to record at same time from all three inputs, I added support for analog loopback.
and ADCMux is now called just 'Capture switch'



If you want to try, you can try ALSA 1.0.15rc2
