how to have /dev/audio on ubuntu?

[Russell Reiter]

Ubuntu did not do a very good job of integrating pulseaudio. It's got
a lot of features but demands complete control over the sound hardware
and it looks like the Ubuntu folks rolled it out too quickly.

If your hardware is older it might be better to go back to ALSA/OSS. I
haven't seen many problems with pulseaudio in newer equipment with
newer installs.

I think ALSA still present in Ubuntu

On the command line
$speaker-test (plays white noise)
$aplay - l (lists playback devices)
$arecord -l (lists record devices)

$alsamixer (make sure PCM volume is not muted.)

or $pavucontrol (under pulse for the same reason.)

Hope this helps
