I'm a tad confused about how to use DAC+ DSP to mix sound coming from the toslink in with sound played on the raspberry pi itself and output both to toslink out.
My understanding is that with alsa many devices take exclusive control of the card, does this mean i'm unable to mix together the audio with the DAC+ DSP? My wish would be to use as simple solution as possible (I'm running raspbian, not hifiberry OS) with alsa.
