Hello.
I am trying to use my microphone (with skype and mumble) but was not
able to make it working. I tried all entries in the fields to select
input, but no results every time.
I have removed the mute in alsamixer and the micro works correctly. I
mean, if I speak in it, I can hear my own voice stronger, so it
probably works (but there is an echo for a reason I do not know. This
will be annoying if it persists, but my first goal is to be able to
use the micro, annoying things I can fix later).
In mumble and skype, when trying to select input device, I have a long
list rather unreadable for me, with info like card=SB (I guess it
means SoundBlaster), DEV=0 or DEV=2 (related to /dev? There are 2
files in /dev/snd/by-path?) and only skeakers/converters/null... but
nothing related to microphone AFAIU.
The thing I really can not understand is why I have 2 sounds cards
(also in /proc/asound/cards) but I have not added any in my computer
(the only related NVidia stuff I have are graphic cards) so I wonder
why there are 2 of them (and I am afraid by the NVidia one, to be
honest).

Your NVidia card has a sound decoder that feeds the HDMI output. If it's
like mine, there is no other sound output connection on it.
In Linux, I have had little to no success using that output; in XP, the
NVidia driver will send the output to your TV, while disabling the
normal sound device.
