oss proxy - emulate oss device using cuse. copyright (c) 2008-2009 suse linux products gmbh copyright (c) 2008-2009 tejun heo tj@kernel.org. well, first, oss refers to open sound system. if it still doesn't ring a bell, think /dev/dsp, /dev/adsp and /dev/mixer. currently, linux supports two audio programming interface - alsa and oss. the latter one is deprecated and has been that way for a long time but there still are applications which still use them including uml (usermode linux) host sound support. alsa contains oss emulation but sadly the emulation is behind multiplexing layer (which is in userland) which means that if your sound card doesn't support multiple audio streams, only either one of alsa or oss interface would be usable at any given moment. there have been also attempts to emulate oss in userland using dynamic library preloading - aoss and more recently padsp. this works for many applications but it's just not easy to emulate everything using the technique. things like polling, signals, forking, privilege changes make it very difficult to emulate things reliably. oss proxy uses cuse (extension of fuse allowing character devices to be implemented in userspace) to implement oss interface - /dev/dsp, /dev/adsp and /dev/mixer. from the pov of the applications, these devices are proper character devices and behave exactly the same way so it can be made quite
