Well, from what i heard this sound daemon does the amplification after
catching the aduio from alsa, at least it can be configured this way. Well
the hardware-preamp is really jsut the last solution, cause why i have a
feature in the sound-driver that can not be used?
but that's an alsa thing, because as i already said, oss doesn't provide mic
support at all for my card.
But unfortunately neither from the alsa-user nor the alsa-devel list came
any response to my request, so i think a lot of work needs to be done to
yupport my driver properly.
Thanks and Regards, Attila.
