I have pasted the output of /proc/asound/card0/codec#0 below, without
the patch. However, I'm not sure what you're exactly looking for? I'm
quite new to all this stuff , but I'd be more than happy to help out
more, so feel free to ask anything.
Also related, in windows (yeah i know), using the IDT drivers, the
volume is extremely high :) So I went searching in the driver files
and it seems that the widget configuration is specified there in an
ini file. As far as I can see, the mixer is not configured, but an
external amp is mentioned. Could it be that the external amp of 0x0A
is not used in snd-hda-intel? Or maybe it refers to the "+3dBV output
option on headphone capable ports" as mentioned in the datasheet...
But I'm just guessing now.
