Posted to alsa-devel under the subject "OSS emulation, period size, and start/stop thresholds", followed shortly thereafter by an actual low-latency ALSA driver. Audio-in to audio-out loopback delay somewhere in the 18 ms range with no underrun/overrun. The actual application is retrofitted to the OSS emulation device for hysterical reasons, but that is also working smoothly now. Don't try the OSS emulation approach on a non-NPTL platform, though; you pretty much have to open /dev/dsp read-write, ioctl it into shape, and service RX and TX from different threads.
