Hello, I am trying to learn about mmap mode of OSS and so far I have this: https://github.com/mekanix/freebsd-src/blob/audio-mmap/share/examples/sound/oss/audio.c. So the device is initialized properly and my code doesn't break trying to write something past the length of the buffer, but I do get strange sound. I am using http://manuals.opensound.com/developer/mmap_test.c.html as reference and the difference that I implemented is that I'm trying to "guess" how long I have to sleep so that when I wake up (and maybe wait a little bit more), I can write the whole buffer. If anybody knows what I'm doing wrong here, please help me. Regards, mekahelp
