When I plug my FiiO E7 USB Audio DAC & Amp in Ubuntu 13.04, it is recognized as Audio DAC but only via the
Analog Output port.
I have to log-out and in again before the
USB Audio DAC Digital Output (S/PDIF) comes available in
Sound settings, which has much better quality.
How can I enable the
Digital Output manually, so I don't have to logout?
