I've set alsa to wake me up every N frames.
Setting the period size makes this possible. The avail_min parameter
only prevents waveups when less than N frames are available.
However, when I awake, I find that I often have fewer
than N frames
available:
snd_pcm_sw_params_set_avail_min (playback_handle, sw_params, N)
err = snd_pcm_wait(playback_handle, 1000);
frames_to_deliver = snd_pcm_avail_update(playback_handle);
assert(frames_to_deliver >= N);
In theory, this should work. Which PCM plugin (device name) are you
using?
