PCM_CAP_COPROC audio device capability

The device has some additional coprocessor (obsolete)


This capability has been used years ago but current OSS versions don't support it any more. It will possible be reused in future which may make applications that use it to break.

Audio device capabilities like PCM_CAP_COPROC can be checked using the SNDCTL_AUDIOINFO or SNDCTL_DSP_GETCAPS ioctl calls.
