Thomas Harte	f3ec7d54bb	Clarifies wait-for-CPU-slot semantics. ... Big bonus: this guarantees `advance_dma`s will be called at most once per output cycle, even if they return `false`.	2021-12-09 19:17:44 -05:00
Thomas Harte	2b0415d552	Attempt to avoid off-by-one buffer reads, add modulation.	2021-12-06 19:28:40 -05:00

Thomas Harte	a5fe1e4259	Largely debugs audio state machine. ... I think I'm still missing an address reload somewhere though, and attachment doesn't actually push.	2021-12-05 15:27:35 -05:00

Thomas Harte	06340b1ad7	Advance DMA pointer, treat audio as signed, request data on low -> high transition. ... There's now some audio, sometimes when there should be. But it's not correct.	2021-12-01 18:34:54 -05:00
Thomas Harte	d23511860d	Attempts audio output.	2021-12-01 06:01:58 -05:00
