Hi all,
I have brought a cheap USB DAC (this one: ebay.co.uk/itm/External-5-1 … 2749.l2649)
It is based on a CM6206 chip. The reason for buying it was needing a SPDIF output and this seemed the cheapest way to try. However I am unable to get it running with the digital output. It is producing sound with the analog however.
lsusb gives:

However in Volumio and in alsamixer there seems to be no way to use it.
Been searching on how to make it work but no luck (although it did show me the commands above so I’ve learnt something at least). Does anyone have one of these and have you been able to get the SPDIF output to work?
