I have a raspberry with volumio installed and a USB 5.1 Audio card(
https://www.amazon.co.uk/External-Sound ... B003TO3KHY). I have read a lot of posts, but nowhere in the instructions what and where to configure. yesterday I was able to get sound from other outputs( I did not understand how), but only on the command "speker test". but when playing audio through Volumio writes an error "failed to open ALSA device "HW:1,0". and now the USB drive has stopped working......help please. really want to get 5.1 sound.
