How to: Tips and Tricks

Ubuntu server: install Alsa sound and MOC (Music On Console)

1. To install Alsa sound (alsa-base, alsa-utils, alsa-tools and libasound2) enter this command:

sudo apt-get install alsa alsa-tools

2. Add yourself to the group audio:

sudo adduser yourusername audio

3. Reboot to take effect

sudo init 6

4. Alsamixer is sometimes muted by default, so you might need to unmute it. Run alsamixer:

alsamixer

Use arrows up and down to change volume, left and right to change source. To mute/unmute press M.

Note: Alsamixer might look different in any machine. It depends on your sound device (sound card). Please, read audio source labels. For example: PCM in Virtualbox is on fifth place instead of the second in VMWare.

Alsamixer in VMWare

alsamixer

Alsamixer in Virtualbox

alsamixer virtualbox

    Well done … I was trying to do exactly same thing. One step where I seems to fail is un-mute master and PCM in alsa mixer. Looking forward to try it again. Thank You!

    Unfortunately, it didn’t work for me. I assume, that Virtualbox might be a problem. I need to test it on real hardware. Shame it might take me another 32 years. But thanks anyway.

    I’ll try it in Virtualbox, and I will let you know about it.

    Yes, yes, yes! Note has fixed it. Mechanicly I was pulling up first two thingis in alsamixer, instead to read which one is PCM. Thank You!

    Thanks that was useful! I had totally forgotten the part about having to be in the audio group…

    Btw, I didn’t need any rebooting, it was sufficient to just logout to effect the group addition. (Well actually I’d also fiddled around sending an “alsactl init” before, when I didn’t get the problem that my user wasn’t in the right group, so maybe that’s also needed if you don’t want to reboot).
