Hi Mike,

HALLAB says that the inputs are not controllable (i.e. No mute or volume control).


Our OXFW971 reference designs only implement master mute and volume
controls, but there's nothing to stop you controlling gain and mute on a
per-channel basis. To save wasted bandwidth, we should probably discuss this
off-line from CoreAudio.

However, I seem to recall that the native Firewire audio driver doesn't
fully support per-channel volume and mute controls via the AV/C command set.
Assuming so, you'll need to write a simple control application to process
the necessary command and response frames. Someone at Apple may like to
comment on how best to avoid any potential conflicts between CoreAudio and a
proprietary control panel.


Vendor specifc commands would work.

Matt
