9efde26514 Async feedback system re-implemented to allow for MasterClock/SampleRate ration not being a power of 2 e.g. 32000Hz from 24.576MHz MClk. 2015-11-20 12:59:57 +00:00

7cd5631e4b The audio i/o core now uses "underflow" sample as it's request word (i.e. different for PCM/DSD). This gets passed all the way through mixer and on to decouple such that it can be used in the underflow state. This allows the removal of the communication of the underflow state to the audio i/o core from decouple and thus "stand-alone" mixer now works again. 2015-03-20 17:23:24 +00:00
