[alsa-devel] Staying synced after underrun

[Paul D. DeRocco]

I'm writing 48KHz stereo to Intel HD audio on my mobo, and I'd like to send
it in parallel to both the analog and S/PDIF outputs, which share a clock
source. If I open both devices, configure them with the same buffer space,
and write the same data with snd_pcm_writei, how should I handle an
underrun? Call snd_pcm_prepare on both device handles? If so, and the first
device underruns, should I bother writing the buffer to the second device?
