If one of your sound devices doesn't work and you get an error similar to <tt>EMU10K1_Audigy: probe of 0000:02:0a.0 failed with error -12</tt> then it might be because the devices are fighting over which sound card number they want to be. To fix this alter the sound card module options (see [Module] page on how to do this). One example of a configuration that works is <tt>options snd-emu10k1 index=-15</tt>. The <tt>index</tt> parameter specifies which card becomes which number, or if negative then it is a bitmask of numbers that it can be autoassigned to. To learn more about this look at the LinuxKernel source file <tt>Documentation/sound/alsa/ALSA-Configuration.txt</tt>
!!! Software Mixing With [ALSA]
+
+ALSA is dmixed by default as of 1.0.9rc2 for the vast majority of consumer sound chipsets. (Ubuntu Breezy was the first version to benefit from this).
You can get [ALSA] to do software mixing for you without having to resort to something like esd(1). This is done via the dmix plugin and as [documented on the ALSA wiki|http://alsa.opensrc.org/index.php?page=DmixPlugin]. Basically, you need to do is get [ALSA] going, then put the following in a <tt>.asoundrc</tt> file in your home directory.
