Hi all,
the new USB DAC from Teac seems detected as 'Human Interface Device' instead of 'Audio'. Despite the fact it is based on a standard USB Audio class v2 controller (Tenor 8802).
Below is dmesg and lsusb outputs.
Does it need to apply a patch in /sound/usb/quirks-table.h ? If yes, someone could help me to write this patch, please?
Your help would be very much appreciated, Thanks in advance.
