Soundblaster Audigy 2 NX USB Sound

mkoljack · 04-10-2005, 10:00 PM

Atm--I placed the new code in the .asourndrc file and restrarted the sound server from the control ctr. with "fixed" as it was and I get an error msg, "device: fixed can't be opend for playback (No such file or directory). The sound server will continue, using trhe null output device" Any ideas?

If you use the default part, then no. It will automatically find it.

Thanks again Atmchicago.

Hi guys!

Thanks for this little howto, now my audigy 2 nx works...but there ist again some cracking in the sound. I play my files with xmms, that showes a rate of 44 KhZ. My .asoundrc:

Code:

pcm.usb-audio {
           type hw
           card 0
        }

ctl.usb-audio {
           type hw
           card 0
        }

pcm.!default {
        type plug
        slave.pcm "dmixer"
}


pcm.dmixer {
    type dmix
    ipc_key 1025 # Should be a unique number
    slave {
                pcm "hw:0"
		rate 48000;
    }
    bindings {
           0 0
           1 1
    }
}

(I used that one of the HowTo and added the rate-attribute)
Can anyone help me to remove the cracking in the sound?

Best regards.

Btw: I've another little problem: My alsamixer-settings aren't saves. There should be a simple solution, but i can't find it...

The ALSA settings are saved as soon as you log out of ALSA mixer. Just be sure the sliders are not off. If you use KDE, use the KMix to manipulate sound settings. Additionally and based on my experience and Atmchicago's help, I recommend for playing XMMS, disable KDE sound from the KDE Control Center, Sound & Multimedia. Then under XMMS preferences, select ALSA sound output. Play away and it should sound great. It has been difficult to have every sound application with no scratching. Atm has been the most help. Also, my sound applications are amaroK (music collection), kaffeine (xine) movies/video apps, streamtuner (audio streams), all the kde apps work great, and the above settings should resolve XMMS for you.

Regards and Hello to Atmchicago-

XMMS also has a plugin for Arts. You should be able to use that in conjunction with the kde sound system. I would switch over to Beep-media player since it's a little nicer, but I haven't looked into getting a similar arts plugin for that, so i'm sticking with xmms when Juk decides to not play my ogg files.

So, theres a rather strange problem now: gentoo doesn't know my nx anymore. I booted today, tried alsamixer...and there's no device....lsusb....no device....?
I've no plan how this could happen, yeaterday, sound worked nearly well. Perhaps any kernel settings that I forgot to set?

moritzmahling · 05-01-2005, 04:13 AM

The problem gets rather strange.. now I booted windows one time up, and suddenly, gentoo knows my nx again O_ò
Perhaps i should say that i doesn't use kde - i use fluxbux, so there's no kde-control-center. In XMMS, I already changed the default output to alsa, and this also works fine...up to this nasty cracking.
(And alsa mixer doesn't save the settings..i've to unmute the card on every boot)

btw: There is no 3d-output.(no subwoofer, no rear speakers) normal? or is there any solution?

Atmchicago · 05-01-2005, 12:47 PM

Yeah, if you don't have KDE then I doubt you're using Arts, so don't bother with that. My subwoofer works, but I plugged my rear speakers into the headphone/middle speakers port because otherwise I don't get sound out of them. But my subwoofer works fine.

moritzmahling · 05-01-2005, 01:07 PM

Okay, now also my rear speakers work well. But theres one big problem: This nasty cracking ... no hint, how to solve this?

Here's my ~/.asoundrc

Code:

pcm.usb-audio {
           type hw
           card 0
        }

ctl.usb-audio {
           type hw
           card 0
        }

pcm.!default {
        type plug
        slave.pcm "dmixer"   
}


pcm.dmixer {
    type dmix
    ipc_key 1025 # Should be a unique number
    slave {
                pcm "hw:0"
		rate 48000;
    }
    bindings {
           0 0
           1 1
    }
}

I have a question: by crackling, do you mean it's running at the wrong frequency? (ie 44.1khz vs 48khz) Or is it something else?

And 2: does that dmixer plugin allow multiple programs to access alsa at the same time? (sort of like arts can do)

moritzmahling · 05-01-2005, 01:49 PM

Yes, I think the cracking comes from the 44khz frequency (also displayed in xmms).

2: Sometimes. ICQ can play sounds with aplay at the same time like xmms, but other programs (like games, cube f.e.) can not. Is installing arts a solution for this and waht do i have to do to remove the cracking?

Atmchicago · 05-01-2005, 02:04 PM

Well arts is a daemon that takes control of alsa and sends all the audio through itself. Artsdsp can be used to launch some programs to use arts, but it doesn't work with stuff like UT2004 (it *used* to, but they gimped it...) But you shouldn't have to use arts.

Try using this as your default and see if it works:

Code:

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

moritzmahling · 05-01-2005, 02:18 PM

No, it doesn't work

Atmchicago · 05-01-2005, 02:54 PM

So you mean that it still outputs the sound but at the wrong rate? Another problem could be if you have an integrated sound card that is default instead of the NX. Is that the case?
