Hello,
I'm quite a Linux beginner. I want to configure sound on my computer in the company. It's small and connected via network to the "real computers" but I have feeling that I might be able to get sound on it aswell. However I don't have admin rights and so I'm a bit stuck with other peoples advice in the internet. Please help me to configure the sound, I will give any information about my system as you may require it, just tell me!
Here are some commands and their results:

(1)
alsaconf
bash: alsaconf: command not found

alsamixer: function snd_ctl_open failed for default: No such device

In the KDE control center, sound system. When I select Alsa as Audio hardware this message is given:
error while initializing the sound driver
device: default can't be opened for playback (No such device)
The sound server will continue, using the null output device

Thanks in advance !!

If this is a company pc, you need to ask the admin to set it up for you. If you hack the system it could be grounds to lose your job and send you down the road. I don't think sound is worth that do you?

You could try "sudo alsaconf" to see if you have access via sudo. When asked for a password, just enter your own password.

If that doesn't work, I think you're SOL.

Basically,
you can't.

I tell you then:
Which system? Suse/Debian/Fedora/..........

It's a debian system.
I tried sudo alsaconf and it did not work.
So if you tell me that it is not possible for me to do this, I won't do it then, of course. It was never my intention to hack the system. However there are configuration options which you can adjust manually. As a beginner, for me it is hard to decide if I just missed something or if it requires admin rights. So thanks for your advice :-)

You're welcome.

in a shell type this:
id

If audio is not shown, forget about listening to music while working

Ask your IT guys, they have no reason for refusing.
