Error while initializing the sound driver:

Suddenly I get:

Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (Permission denied)
The sound server will continue, using the null output device.

---

When logging on as anyone other than root (sound works fine as root).

/etc/group reads:

audio:x:29:john:knoppix

/etc/group.org reads

audio:x:29:knoppix:john

all the dsp devices are root audio.

Any ideas? And can anyone tell me why there are group and group.org ?

Suddenly I can't pon as anyone other than root either. There doesn't seem to be any logic to this: all the entries suggest either user should be able to diallup, but the occurences do seem to have something to do with editing /etc/group.

Well, I got the sound up and running by doing

chmod a+rw /dev/dsp /dev/mixer /dev/sequencer /dev/midi

as root, natch

(fortunately I'd kept the instructions for installing alsa from source, no, I didn't re-install, just ran the code above) but still trying to work out why I can no longer pon as anyone other than root. :?

For the /etc/group file doesn't it need to be in the format of:

audio:x:29:john,knoppix

?

--This is how it looks on my system:

ls -l /usr/bin/pon
-rwxr-xr-x 1 root root 956 Nov 24 2002 /usr/bin/pon

--You might try ' chown USER.root ' on pon. If that still doesn't work you could try ' chmod +s /usr/bin/pon ' to setuid root on it. But if you do that I would ' chmod o-rwx ' on it, too, so other users can't get at it.

Thanks. I tried both and rebooted and now have both sound as user john and pon and poff :D I'm not sure which worked, yet, but WTH :wink:

Thanks again.
