I was wondering if anyone has ever been able to resolve the issues
that exist with the sound card below and the low gain of the internal

the internal mic extremely low and almost impossible to hear
sometimes.
Are their hidden mixer options which include a "mic boost"? It
increases the gain of the input amplifier. You may need it off to
record really loud sounds (where turning the level down doesn't stop the
pre-amp from clipping ahead of the level control), or you may need it on
to increase the gain. It's an option that's often needed.
I can remember that most windows machines have it. I haven't seen this
option on a linux machine for a while. I do agree with you I need that
option to make my mic work well but that option is no where to be found.
I found something for alsa which creates a pseudo booster, it kind of
works but puts a lot of noisy in the sounds and not all applications can
see it.
Do you or does anyone know hot to enable to mic boot option?
Thanks
