I recently bought a Audigy2 NX USB soundcard for my Dell Inspiron 5150, so here is a brief step-by-step of how I made it work:

1. Recompile kernel (linux-2.6.7-gentoo-r7) to include the ALSA USB device driver.
Code:

Device Drivers -> Sound -> Advanced Linux Sound Architecture -> ALSA USB devices ->
<*> USB Audio/MIDI driver


Make sure you don't compile USB audio support in, since this seems to generate conflicts, i.e., only compile the ALSA USB device driver.

2. Modify /etc/modules.d/alsa
Code:

alias snd-card-0 snd-usb-audio


3. Write ~/.asoundrc file (without this you'll get poor and distorted sound)
Code:

pcm.!default {
type plug slave {
pcm "hw:0,0"
rate 48000
}
route_policy default
}


Since I don't want to use any other sound devices, I made the Audigy2 device the default device. This makes life easier, so you don't have to configure the device used by each application. If you have more soundcards, then you'll probably want to modify the .asoundrc.

I haven't found much info for Audigy2 NX under linux and I haven't been particularly systematic. somehow it works though.

Currently, I only use headphones so I can't report on any of the other features. I hope to add information on this later.

Hi. Thanks for the howto, I've been thinking of purchasing one of those for my laptop for a while, but I just couldn't find much info on it.

Specifically though, do you know if the 5.1 sound works, or at least 4 channel, if only with replication?

Currently, I have only been using headphones, so I cannot answer your question. I plan to try it out in the near future though. I'll add it to the HOWTO, if I can get it working or not. Like you said there isn't a lot of information available, so I hope to provide some here for anyone interested.

5.1 works, but CMSS (2 -> 5.1 Upmix) doesn't.

I follow the steps and I can select audigy in kmix but the sound still coming out from my onboard soundcard and the mute light at the audigy externall controller is always on. I cannot unmute it.

any suggestions?
