I installed Debian+XFCE using VMware and this YouTube video.

Everything runs OK, but I have no sound in the VM. What's wrong?

What host OS are you running VMware on? What are the related sound settings in VMware? What virtual sound card is presented in Debian? Did you check mixer settings e.g. using alsamixer? – gertvdijk Dec 17 '12 at 13:56
@gertvdijk I am running VMware Workstation on Win7 64bit. Related sound settings in VMware: "Use default host sound card" Virtual sound card presented in debian: ENS1371 - Ensoniq AudioPCI alsamixer's output is that everything is 100% – Ghost93 Dec 17 '12 at 14:12
Also unmuted? What are you doing to produce the sound output in the VM? Did you try speaker-test for example? – gertvdijk Dec 17 '12 at 14:17
How to check if it is muted or not? And I try to play a youtube video and a mp3 file using VLC – Ghost93 Dec 17 '12 at 14:20
On the bottom of the individual channels in the mixer there's either "OO" or "MM". O = open, M = muted. Toggle with keyboard "M". – gertvdijk Dec 17 '12 at 14:24

Already verified solution from the comments, so posting as an answer.

Check for muted channels in the alsamixer. Muted channels are indicated with an MM state at the bottom of the vertical slider. Unmute it by selecting the right one using the arrow keys, then pressing M to toggle mute/unmute.
