I've got my Audigy2 NX working in Linux using the USB Audio ALSA module but for some reason the sound crackles and seems to be off tone. Originally I just thought this was a problem with the module but my friends says it happend to him too and he's just using a normal SB Live! card with the emu10k1 module.

Any ideas?

You're actually not using ALSA if you're using the emu10k1 module because the ALSA module for the Audigy and SB Live! is snd_emu10k1. That means it's using OSS, because I had the same problem when using OSS for my sound. So go to wherever your module autload file is (and make sure the kernel you are using has ALSA compiled into it with the sound driver as a module) and add snd_emu10k1 to the file. For me in Gentoo it's /etc/moduleautoload.d/kernel-x.x.x, but I'm not sure what distro you use so you might have to consult somone on that exact location.

As for ALSA, you'll need the tools for it, so open a terminal and type 'alsamixer', and if that comes up then you have all that you need. Play with the settings in there and possibly recompile the kernel without OSS since it might conflict with ALSA.

I'm not using emu10k1. I know that the ASLA modules are snd-... The module I have included in my kernel is snd-usbaudio (I think that's the name). OSS doesn't come with USB Audio support, as far and I'm aware, otherwise I would use that. There is a module in USB Devices in the kernel called usbaudio and I've tried that but it doesn't pick up my sound card. I've run alsamixer (actually, gnome-alsamixer) and I can play around with the sound settings it's just the crackling that's bothering me.

hi all,
here's quick hack to get a good output from your new Audigy2 NX (it works for me TM):

edit your ~/.asoundrc so that it contains the following lines:

pcm.rate48 {
type plug
slave {
pcm "hw:0"
rate 48000
}
}

than configure your palyer of choice to use rate48 as the audio output device....

now you enjoy your favourite Black Sabbath track


basically I noticed that 48000 Hz encoded audio plays well, those line you put in asoundrc simply converts any rate to 48000 ... thanx to the alsa guys for making it SO easy (Imagine yourself doing it on winzoz ahahahaha)!


PS: you must use alsa.....

Thanks for the reply but since posting I'd already found that out. I'm using this though in case anyone else is interested...

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

I do have another question though. Does anyone know of a way to set the device you define as default? I use quite a few programs which use OSS through the OSS emulation layer but that only uses the default device. I have found that most programs do allow you to set the sample rate or device as a parameter but others don't so I would like to use 48000Hz as default.

Cheers,

Darrell

hum, that seems a fine answer for my problem

but where are .asoundrc or soudrc.conf supposed to be? I haven't found them anywhere on my system, so what do I need in order to make sure the files are being used as they're supposed to be?

I'm having the same problem; where do I put redneon's fix to have it apply for all users? (If it's soundrc.conf, where should I create it?)

Also, is there any work being done on better ALSA support for the Audigy 2 NX?

Muchos gratos

update....


the sound crackling isn't there anymore. I have absoutely no clue where it came from, that resolved itself after a few hours of playback (?!?)

but the volume knob still doesn't work, and that really saddens me :-(


have a nice day
