(I missed this post, but got contacted about it directly off-list. I'm probably a good person to contact about this sort of thing). The sample rate and number of channels need to exactly match the device for ideal output. The ffmpeg OSS code looks very primitive. I might be persuaded to write a backend that does detection of device characteristics. It's basically required for proper audio recording on NetBSD. Note that our OSS emulation doesn't match the spec exactly, and is also undocumented, so doing anything non-trivial is hard. I don't recommend writing new code that uses it for that reason. Out of curiosity, does Audacity work for you (when set to single channel 16-bit PCM, etc - it defaults to 32-bit floats which won't work).
