I tried turning off and back on my pre/pro+amp ( Yamaha DSP-A1 ) that didn't work for me nor did rebooting my computer.
Since PCM via spdif should get send at a fixed clock rate, I think the computer side might go out of of sync since when it brakes. Just running "speaker-test -D spdif -c 2" fixes it for me more than once. My guess is that that command restarts the clock spdif is using or reinitialises it.
