Hi!

Sorry to unearth this topic but I had a strange behaviour with my Mini this morning.

I needed sound output for a quick test so I (re)tried to use a cheap USB audio adapter.
Once I connected the adapter, I got System sounds (mainly the ones from the OS theme) but no "standard" sound (from Quicktime Player or by playing an Audio CD in iTunes).
So I tried to reboot but with the adapter already connected.
Now, I got sound from my adapter.

OK but what's new ?

The first time, when I connected the adapter, it appeared in the Sound control panel.
When I restarted the mini, no adapter visible in the Sound control panel.

Does anyone have an explanation ??

Also ...  the control panel kept the "Main volume" to 0 even if I had sound in my speakers.  O_o
