The driver supports PCM playback and capture substreams, jack and channel map controls. A message-based transport is used to write/read PCM frames to/from a device. As a device part was used OpenSynergy proprietary implementation. v6 changes: - Code readability improvements suggested by Takashi. - Added additional comments about PCM message lifetime. - Temporarily removed DEVICE_NEEDS_RESET device status handling. Some kind of assistance from the virtio bus/level is required. In turn, this requires a separate discussion of the possibility of implementing such handling for virtio devices whose configuration may change (which may require re-probing, like in case of the sound device).
