Andreas Kling	983245113a	SB16: Write the correct DMA buffer offset for 16-bit samples. ... Also switch to using single-cycle mode for now. It would be nice to add support for auto-initialized mode but this works okay at the moment.	2019-07-13 21:28:35 +02:00
Andreas Kling	02c3c737f6	SB16: IRQ handler should send 0xd5 to pause 16-bit playback. ... We were sending 0xd0 to pause 8-bit playback. Not sure if this actually makes any difference but it seems like the correct thing to do. Also update 'm_interrupted' *after* handling things.	2019-07-13 20:43:38 +02:00
Andreas Kling	dcfa93e71f	SB16: Use a snooze alarm to block the current thread while playing.	2019-07-13 20:15:17 +02:00
Andreas Kling	b51f0f7bfa	SB16: Put debug spam behind SB16_DEBUG.	2019-07-13 17:55:48 +02:00
Andreas Kling	48bde0393e	SB16: Use Stereo samples by default.	2019-07-13 17:51:36 +02:00
Andreas Kling	d63b6e624e	SB16: Send (sample count, less 1) to the DSP, not the number of bytes. ... This worked fine when we were using 8-bit samples but broke on 16-bit.	2019-07-13 17:47:57 +02:00
Andreas Kling	781a28f3ed	SB16: Switch to signed 16-bit 44100 Hz Mono by default. ... We should switch to Stereo but I'm having some trouble with that locally.. Since we intend to mix everything through SoundServer, let's just put the card into 16-bit mode right away.	2019-07-13 17:12:33 +02:00
Robin Burchell	6c4024c04a	Kernel: First cut of a sb16 driver ... Also add an AudioServer that (right now) doesn't do much. It tries to open, parse, and play a wav file. In the future, it can do more. My general thinking here here is that /dev/audio will be "owned" by AudioServer, and we'll do mixing in software before passing buffers off to the kernel to play, but we have to start somewhere.	2019-07-13 08:00:24 +02:00
