Well, I have this problem for a while now. When my computer start the mic seem to work but it's like it's muted. I have to go to a terminal and type alsamixer -c 1 and then I set up PCM Capture Source on Line and set up it back to Mic to get the mic actually working. Is there is a way to do this automatically or to solve the problem.

I use a special workaround on this card because of the bug #429642. My workaround is having this at the end of my /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf :

[Mapping xmod-stereo-out]
device-strings = surround51:%f
description = Analog Stereo Creative Xmod
channel-map = front-left,front-right
paths-output = analog-output analog-output-headphones analog-output-mono analog-output-lfe-on-mono
paths-input = analog-input analog-input-mic analog-input-linein analog-input-aux analog-input-video analog-input-tvtuner analog-input-fm analog-input-mic-line
priority = 10

Maybe the bug come from here, maybe I have to change something.

Thank you for any help.
