PCM_CAP_BIND audio device capability

The device supports the old output binding calls (obsolete)

Description

This capability means that the device supports the SNDCTL_DSP_BIND_CHANNEL and SNDCTL_DSP_GETCHANNELMASK interface which is not part of the official OSS 4.0 API. However some other OSS implementations may still use it.

New OSS applications should use the SNDCTL_DSP_SET_PLAYTGT interface instead. There is no capability for this interface because it's supported by all OSS 4.0 compatible drivers.

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