>Description:
CS42xx based sound cards controlled by newpcm driver uses mixer
registers table 'mix_devices' defined in /sys/dev/sound/isa/mss.h
As described here, 'line' uses registers 18 and 19, 'synth' - 2 and 3. But really some (or probably most... or jast all) CS4232 based cards
uses 2 and 3 registers for 'line' and 18, 19 for 'synth'.
Also, CS4235 have "master out" AKA 'vol' device at 27 and 29 registers.
>How-To-Repeat:
Plug some audio source to "line in" of sound card.
try "mixer line <level>" and "mixer synth <level>" to
change volume.
>Fix:
'mix_devices' definition should contains following lines for CS4232
MIX_ENT(SOUND_MIXER_SYNTH,      18, 1, 0, 5,    19, 1, 0, 5),
MIX_ENT(SOUND_MIXER_LINE,       2, 1, 0, 5,      3, 1, 0, 5),

and following one for CS4235
MIX_ENT(SOUND_MIXER_VOLUME,     27, 1, 0, 4,    29, 1, 0, 4),
