<br>
aplay -l<br>

if that shows stuff, you have the right drivers. If not, start looking for the<br>
device and driver with<br>
<br>
sudo lshw -C multimedia<br>
<br>
Sometimes it is a simple device/file permissions thing or an old config from<br>
prior releases - clean out the ~/.asound stuff and perhaps the /etc/alsa stuff.<br>
<br>
I've almost never had good luck with pulse-anything. Find it easier to purge<br>
from the system. The output from aplay -l tells you which devices to setup in<br>
the /etc/asound.conf - so decide if you want analog or digital output and which<br>
device you want to get it ... speakers, headphone, HDMI, digital coax or toslink<br>
... there will be a different device (should be) for each.<br>
<br>
Plus don't forget to verify that auto-mute isn't enabled through alsamixer. I<br>
hate when that happens.<br>
<br>
Anyway - hope that is clear enough to get started.<br>
