I have tried both RaspyFi and the latest Volumio release and have not has any success with my Must DAC. Here’s a link to the same model on Ebay: http://www.ebay.ca/itm/MUSE-Mini-24Bit-192Khz-Coaxial-Optical-USB-Input-DAC-Headphone-Out-Black-/130854717598?pt=US_Home_Audio_Amplifiers_Preamps&hash=item1e778c889e&_uhb=1
It seems to power up alright but Volumio is not seeing it. From the product description : Based on CS4344 DAC chips and one CS8416 digital receiver from Cirrus/ CM102AH as USB receiver.
I’ve used it in desktop versions of Ubuntu and LinuxMint so there must be some Linux support. Any thoughts?
