 |
|
Hi,
Subject pretty much says it all. I have an onboard intel_hda card and a webcame. Alsa always chooses my webcam as the default. I've tried the handbook and the alsa webpage unfortunately I'm kinda stuck. According to them I'm supposed to change the order of my cards listed in there, but I can't find anything about my webcam in
/etc/modprobe.d/alsa.conf
| Quote: |
cat /etc/modprobe.d/alsa.conf
# Alsa kernel modules' configuration file.
# ALSA portion
# OSS/Free portion
##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
## ALSA portion
## alias snd-card-0 snd-interwave
## alias snd-card-1 snd-ens1371
## OSS/Free portion
## alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
##
# OSS/Free portion - card #1
## OSS/Free portion - card #2
## alias sound-service-1-0 snd-mixer-oss
## alias sound-service-1-3 snd-pcm-oss
## alias sound-service-1-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

and here my /proc/asound/cards

cat /proc/asound/cards
0 [Q9000 ]: USB-Audio - QuickCam Pro 9000

At some point I had it working, I used to have a Sound option in System->Preferences I changed the default mixer to my card and restart alsasound, but after an update world it's gone. |

Another possibility is to simply blacklist the alsa module you don't want to use. That works well on my laptop, with my usb sound card.

That's not really an option because I actually want to use my webcam, I just don't it being selected as the default device. |

You should be able to tell it the order of the cards, with something like
| Code: | options snd-hda-intel index=0
options snd-usb-audio index=1 |
Other things to try - probably add a line "options snd cards_limit=2", creating sound-slot-1 and snd-card-1 aliases for the usb driver. |

I got it to work by reading the alsa web page for my specific soundcard alc1200. Pretty much to fix this problem and the problem I had with not being able to play from multiple sources (ex. flash and mpd or mplayer) was by adding the following to
| Quote: |
pcm.hda-intel {
type hw
card 0
}
ctl.hda-intel {
type hw
card 0
}
