I've install LICQ, but as recommend by the package, I also install SOX. Then I start LICQ as a normal user. Whenever there is incoming message (a sound accompanies it), I have the following error on the terminal:

sox: Can't open output file '/dev/dsp': Permission denied
playing /usr/share/licq/sounds/icq/Message.wav
sox: Can't open output file '/dev/dsp': Permission denied
playing /usr/share/licq/sounds/icq/Message.wav

Is this the correct permission for the dsp file in /dev?

david:/dev# ls -l dsp
crw-rw---- 1 root audio 14, 3 Mar 15 2002 dsp

All the files in /dev seems to be owned by root though. Does that mean I can only run LICQ as root to have the sound properly played?

Thanks !

You should have the file writable (and readble) by others.

"crw-rw-rw- 1 root audio 14, 3 Mar 15 2002 dsp"

What command can I use to list those in 'Audio' group?

Thanks

that's a way to do it, the more proper way is adding your user to the group audio:

adduser username audio

choose for username your own username.

I've had the same problem. Quite stupid the user isn't added to the audio group automatically...

I've added the user into the audio group. However, the same error persists:

david@xdavid:~$
** WARNING **: oss_open(): Failed to open audio device (/dev/dsp): Permission denied

Is there any command to list the users in 'Audio' group for me to verify?

PS. Running Xmms as root works perfectly.

Thanks !

su
chmod a+rwx /dev/dsp* /dev/mixer*

ps: avoid X usage as root

@mrcheeks
that way too much

just

chika:/etc $ sudo chmod o+rw dsp

[then make sure that it show like this]
chika:/etc $ ls -la dsp
....
crw-rw-rw- 1 root audio 14, 3 2009-05-06 02:40 dsp
....

Have you seen the date on this thread?

but, i come with the same problem
n the solution is there... i just send the conclusion

btw, thanks 4 reply


add me ym: chika.tambun

First user created is automatically added to video and audio group. Next ones need to be added manually.
I've never found a command to list users present in a group but
grep audio /etc/group will give you the list of users minus the user that has the same name, if any:
user:x:1000:
audio:x:29:user
