ALSA audio output experiment
...
I think it's smart to rather use ALSA directly instead of PortAudio.
ALSA is push AFAIK, and talking about it here at the hackspace, seems
like the better choice. It's a bit lower level, but anyway everything
speaks ALSA anyway. It's not like there's any reason to use PortAudio
at all. It's just an extra abstraction.
Coding for ALSA it'll also work with Pulseaudio and esd. Do people
really use other sound systems than Pulseaudio, esd or plain ALSA?
I can't think of it.
I really the idea about building a small tool first. I'll do that.
Also thought about making a small blikning cursor/text output, and
syncing a BEEP-sound to that, so that I can test around with throwing
in lots and lots of latency between "me" and the video, and try to
sync it anyway.
I should be able to read back from the sound card (or pulse audio
underneath, it will just work with alsa as the abstraction) how long
it takes for the bytes I'm pushing to reach the speakers, and do some
buffer tuning on that.
