The ALSA guide currently details how to build support for multiple sound cards but not how to use them. Basically we just need to say how to use alsamixer to unmute the second sound card, and say that each application needs to be told which sound card to use (maybe provide an example for ogg123 or something). Also, if we can explain how to change the default sound card without confusing the user too much, that would be nice (but not really essential).
Adding a note on how to configure dmix *and* applications correctly should be great, too. Since alsa/1.0.9 (iirc) dmix is used by default, but when you want some application to use "second soundcard", you tell it to use device like "hw:1.0" which is not dmixed.
Any of you with two sound cards? I don't have two (tried, but couldn't get my hands on one..) and without that I really can't do much on this bug.
(In reply to comment #2) > Any of you with two sound cards? Yup. I haven't figured out any way to fix comment 1 yet, though. If you only need examples about how to set up different sound output in applications, I might help you.

Hello, I've been working on a new ALSA guide that describes how to do multiple sound cards very easily on the wiki. Maybe we can merge the two documents. http://gentoo-wiki.com/HOWTO_ALSA_Complete_%28includes_dmix%29 Section #2 would be the part in question. I think this can be resolved rather easily. --Jason Weisberger jbdubbs@gmail.com
hi all; i have started effort on adding a new section to alsa-guide.xml and so writing the requested info in this bug (since i had one two) (gaming and music at the same time); but since i stopped that i don't use it anymore. first draft expected *soon* greetings diox
Well, I've since updated the ALSA guide to include a new bit about support for multiple sound cards, so do take that into account. And, if you ask flameeyes very nicely, he might even help out a little --- he runs multiple sound cards it seems, and certainly knows how to set them up.
Dimitri Got more news on the update? I can merge some information from the Internet with the guide but am not in the position to test it.
Given comment #6, with the blessings of fox2mike I hereby close this bug. All hail!
