Still fd=9 (audio fd) is not specified when poll is called. So the application doesn't ask for OSS related events and poll will not return any of them. However both GETIPTR and GETOPTR seem to get called and it seems to return proper values. However there seems to be long pauses between subsequent GETIPTR calls. These delays must be seconds since the fragment counter gets incremented by 88 or 181 fragments between calls. This indicates that there are some logic problems in pulseaudio. Actually I don't think using mmap() gives any benefit to pulseaudio. It's just an Über sexy looking feature that programmers like to use. Pulseaudio seems to have implemented its own read/write routines on top of mmap() which doesn't make any sense.
