I don't have much experience myself, but in such a situation I would recommend either increasing buffer size, or linking capture and playback devices with snd_pcm_link().

Thanks for the input. In the end, I hacked up a version of the test/latency.c to do what I needed. I think the root of the issue is that ALSA behaves badly if both the period and buffer sizes/times are configured, and the values provided do not match up (in terms of the buffer size relative to the period size).

Anyway, I've got it working now, so thanks anyway!
