Cameron Grant 285648f9d2 beginnings of virtual playback channel support ... instead of using two malloced arrays for storing channel lists, use an slist. convert the sndstat device to use sbufs and optionally provide more detail about channel state. vchans are software mixed playback channels. they are not enabled by this commit. they use the feeder infrastructure to emulate normal playback channels in a manner transparent to applications, whilst providing as many channels are desired, especially suitable for devices with only one hardware playback channel. in the future they will provide additional features. those wishing to test this functionality will need to add vchan.c to sys/conf/files and use 'sysctl -w hw.snd.pcm0.vchans' to enable it. blocksize and auto-rate selection are not yet supported.		2001-05-27 17:22:00 +00:00
