hi Pascal Hibon,
I have tried similar /etc/asound.conf files. The sound does come out of
both (ananlog and usb in my case) but the sound is very distorted. I
have been unsuccessful in tuning for the Raspberry Pi or finding a
working solution on the internet specifically for the Raspberry Pi.
I have read that XMBC on the Raspberry Pi supports dual output channels
but I haven't found out how they did it.
regards
Greg
