Soundblaster Audigy on Knoppix

**Dark-Prophecy** · 11-09-2003, 07:31 AM

I just install Knoppix and my sound is not working. I am a COMPLETE newbie to linux as I am now dual booting XP and Knoppix now. Please help me, thanks. As the title says I am using Soundblaster Audigy.

This is the error I got when I tried sndconfig
The module used for your card emu10k1.o, is not currently in your module search path. Please verify that your kernel modules are correctly installed.

See, it detects my soundcard fine, but then it gives me that message.

You need to use the alsa cheat code. i.e. at boot, type

Code:

knoppix alsa

How do I do that? When I boot, out comes LILO and the boot menu. I don't have a choice. Sorry I'm a newbie.

I did an HD install, so it doesn't have a boot prompt.

Try as root /etc/init.d/alsa-autoconfig if it works and you get sound then also as root edit the file /etc/init.d/bootmisc.sh and add the line aumix -w 75 -v 75 near the bottom of the file this sets the default volume on boot.

I was also having problems getting sound. I tried what you said & it worked but I had to start xmms from console as root. On the next boot I got an error 'couldn't open device /dev/dsp (Permission denied)' & again no sound unless I started xmms from console as root. permissions for /dev/dsp are user =root, group=audio, rw for user & group. I assume these are default values. What else do I have to do to get sound as user without having to start xmms as root?

Is the user a member of the audio group? To check use groups or id if you are not a member then adduser user_name audio as root then logout and back in for the changes to take effect.

Tried adding the user to the group 'audio' using KUser. Oddly, had to add root also...no users were checked off by default. That stopped the 'can't open /dev/dsp errors' (BTW did not get the error when logging on as root) but hen XMMS wouldn't run. It would just start up, display the xmms screen then freeze. Had to use ctrl-alt-esc to kill it.
Maybe I've done something bad to the basic system. This is on my laptop, Dual boot Win ME & Knoppix, only 6G HD so minimal room for Knoppix, so I've tried to eliminate unneeded stuff to gain some space & maybe I've trashed something which was necessary.

Check for the artsd daemon running it screws up xmms all the time if you do not have the plugin installed and enabled. Try when the problem happens ps xa| grep arts then kill of the number of the arts process. Alternatively you can install xmms-arts and use that for the output plugin instead of the OSS plugin.

can't get ps xa /grep arts to work, gives bad syntax errors but ps x gives a list & there is no artsd running. also I get error 'rpcinfo: can't contact portmapper: RPC:remote refused' but then it goes ahead & adds the user to /etc/group.
This is definitely a permissions problem of some kind. When I do not have user as a member of audio, xmms plugin works & I can get sound as root, either logged on as root or sudo'd. but as user I get 'cannot open /dev/dsp' error while logging in & get errors when the xmms plugin tries to open. (These errors only started after I added the aumix line to bootmisc as suggested above). When user IS added to group audio, xmms plugin stalls whether being called from root or from user. Won't play sound, won't close.
Late breaking news...it DOES play the sound, it just waits about 30 seconds before it plays!??! but it still won't close.
