Hi,
Yes, it is !
It works now ...
What is the aim of this parameter "snd-usb-audio nrpacks=1" and what does the value "1" mean regarding the default value "8" into modprob.conf ?
Thanks a lot for your reply.
After one day test, it works ... technically... but musicaly, it is cheap and fast quality...

The sound is very flat, thin, harsh and numeric, without fluidity. I don't know if it is caused by hardware or software but I can't obtain an acceptable result. My squeezebox Touch produces a result in a higher category.
Perhaps a Squeeze OS would be better customized than runeaudio for Odroid ...
