I've added an ALSA (English) category as this is a pretty large topic and will benefit from grouping pages together. I'll be working on hunting for more pages as I can. --Multiphrenic 13:57, 27 April 2011 (EDT)

I don't think this category is necessary; I doubt you'll find much else that belongs here. -- pointone 22:35, 8 May 2011 (EDT)

Adding udev rules for usb sound cards?

I used this udev rule to allow for hotplugging of my usb card and defaulting to the system card if the usb card is not present. http://kitenet.net/~joey/blog/entry/random_tip_redirecting_alsa_to_usb_sound_card/ Someone might want to add this to the wiki. I don't have time now but if I get it I will. Lmn123 01:26, 24 January 2012 (EST)

Modified HDMI Does Not work.

I added the line that included just restarting alsa. It seemed weird that the only method offered was to restart the entire system. If this causes any harm please correct me. I have tried this myself and it seems to work just fine.--Shoe 04:54, 16 August 2011 (EDT)

EDIROL UA-1A and Intel HDA: What worked for me

I will put this here as I have not yet understood the magic of ~/.asoundrc and because I am not sure if it were a good addition to the article.

After trying countless of configurations, I found one that allows me to 1) set the default sound card, 2) play multiple sounds simultaneously for both devices, 3) still use alsamixer (many configs gave me "cannot open mixer: Invalid argument").

/etc/modprobe.d/alsa.conf
options snd-hda-intel index=0
options snd-usb-audio index=1
~/.asoundrc
defaults.pcm.!card 0  # set to 1 for snd-usb-audio
defaults.ctl.!card 0  # set to 1 for snd-usb-audio
defaults.pcm.!device 0
defaults.ctl.!device 0
