I don't understand how the two devices can be locked together.
For the SPDIF inputs to be available on the fast track ultra 8r, external clocking needs to be selected.
The M300 manual doesn't mention any way to set the M300 as clock master.
Good work though Benny.
which may explain the pops and clicks he's still getting.
I don't have a fast track ultra 8r...but he should be able to change the hardware I/O to external and leave the internal PT clock as the master. The M300 is looking for a master clock (the original source) and is spitting out the same clocking source back to PT on the return. Should be done in the hardware menu.
From the PT manual for LE (I couldn't find anything specific to the fast track):
If you want to use the digital inputs and outputs
on your Pro Tools system as effects sends and returns
to a digital effects device, Pro Tools should
be the clock master in most cases. Set your digital
effects device to accept an external digital
clock so that it synchronizes to Pro Tools.
To set up a digital send to an external device from
a 003, 003 Rack+, 003 Rack, Digi 002, or Digi
002 Rack system:
1 Choose Setup > Playback Engine and choose
the peripheral.
2 Do one of the following:
• If the external device is connected to the
S/PDIF RCA jacks, deselect S/PDIF Mirroring.
(When S/PDIF Mirroring is on, digital
output at the S/PDIF RCA jacks exactly mirrors
the output of analog Channels 1–2.)
• If the external device is connected to the
Optical ports, choose a format (most likely
S/PDIF for an effects device) from the Optical
Format pop-up menu.
3 Choose Internal from the Clock Source pop-up
menu.
4 Click OK.
5 Optionally, configure the I/O Setup dialog
with new path names for effects routing.
