Webcam with mic interfering with sound
Hi all,
im a new mepis user, so please forgive me if my "noobness" offends.
i have successfully installed simplymepis which is dual booting with xp home
i have a labtec webcam which has a builtin microphone in it, which is causing my sound to stop working in mepis. i have tested this by unplugging the webcam and booting into mepis upon which sound works.
i would prefer not to have to keep unplugging the webcam if possible purely on the matter of convienence. Any ideas how to make my sound card (sis si7012 btw) work without having to unplug the webcam? i thought loading kmix and selecting the right mixer would fix it, but i was wrong.
thank you for you time to read this, any solution would be greatly welcomed.

ps: how do you pronounce "mepis" ?
no work required
hi,
all i do is take the usb webcam out before i start up the computer.
does it do this because usb detection comes before alsa?
does kmix load automatically for you? i did accedentally stop it from loading when i was trying to figure this one out.
theres an alsa command you can type to see what devices it thinks you have, as im at work at the mo, ill reply again when i get home... or you can type "alsa" without quotes in a shell and press tab twice to see the three options.
any further takers on this issue?
thanks for your reply nd3
Fixed
sorry to bring back an old post, but i have solved this issue. the webcam with mic was taking priority because it was being detected first. so a little detective work and i found out the following fix:
if you add "options snd-usb-audio index=-2" without quotes to the bottom of /etc/modprobe.d/alsa-base , it will stop any usb audio device from taking priority in alsa, so i can now leave my webcam with mic plugged in without it interfering with mepis.

Using Mepis...and proud of it.
I've done this too
Thanks for the fix, I wish I found this post earlier.
Here is the fix I ended up finding for my sound
While browsing a zillion posts on google I came across somthing regarding usb-audio or other usb mic etc. in the system.
Appearantly other usb devices can cause problems.As if you have 2 sound cards in the machine. So to test this theory I removed my usb webcam with built in usb mic, and BOOM the sound is working on re-boot.
So in order to make changes perminent, I added this line to my (sound) file located at:
etc/modprobe.d/sound
alias snd-card-0 snd-via82xx
options snd-via82xx index=0
# NOTE: snd-via82xx is my sound-card module
alias snd-card-1 snd-usb-audio
options snd-usb-audio index=1
So having said this, Note I made the usb-audio the second device by adding the index=1
At least I think thats what this means.
And the sound card is index=0 so I believe this makes it the first card in the system.
All appears to work well so far.
I'll have to work on the alsactl restore failed error later, which has something to do with the stored state, volumes levels etc.
Anyhow this should get sound working.
Note:
Change the line snd-via82xx which is my sound card with driver for your sound card
My sound is a via8235
Hope this helps
agent86, have you tried the
agent86,
have you tried the fix i posted? this doesn't necessarily force the sound card to be 0, it just makes sure that the usb-audio is anything but 0. this might solve your alsa config issue.
