* audio: keep blocking AudioOut writes on an even cadence The blocking queue check only enforced a minimum cushion, so the guest could queue a burst of buffers and then be blocked for the whole cushion. Measured on PPSA03647, intervals between guest writes alternated between 0 ms and ~44 ms instead of one 5.33 ms buffer period, while the average rate stayed correct at 48000 frames/s. Mixers that run on a timer cannot track that cadence and the music turns slow and warbling. Keep the cushion as-is, but also hold writes to the buffer period, and skip that wait when the stream is running low so it cannot underrun. Intervals become ~5.4 ms with microsecond-level deviation and the menu music plays correctly. * audio: reuse output clock after SDL queue priming --------- Co-authored-by: nmzik <Nmzik@mail.ru>
