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.
To do this automatically, amixer should do the job. It's the command-line-tool for Alsa-Mixer.
If you have two sound devices, maybe Pulse is trying to use the mic from the first card (-c 0) not the second (-c 1 -- your Creative). Install and run
pavucontroland when you try to record, check which device it's trying to use. If the wrong one, change it.
