Re: [alsa-devel] Asynchronous ALSA - callback and latency questions

...

I’m using ALSA for building a performance musical instrument, so I’m after low-latency audio output.

1. I’m using asynchronous audio output (i.e. using a callback).

Don't.

That's an interesting insight. I reckoned using a callback was the most elegant solution since that's what I'm used to for DirectSound, iOS, OSX, WMME, ASIO etc.

So what would be the most bulletproof way of dealing with streaming audio instead? Can I do polling in a non-blocking state? I think blocking-state audio is out of the question since I do need to handle MIDI I/O and UI events at the same time.

Thanks Bram
