Hi, just yesterday I figured out, that the davinci sound driver seems to have problems with mono. I also wrote an application and told to record only one channel, and the davinci sound driver confirmed the setting to one channel. But it just used two channels. With playback it was the same. That seems to be a bug in the driver. I think that's why NUM_CHANNELS=2 is solving your problem.
The same program (with alsa oss emulation) on a PC just did (mono or stereo) what it was told to do. A word on OSS: The driver seems to be using the 3.0 API and not the 4.0. So for details please refer to http://www.opensound.com/pguide/ and the OSS v3 Programmer's guide (PDF). That means not that the OSS v4 documentation is useless, but not all is applicable.
