Again with the Delta 1010LT...

[Ludwig Schwardt <schwardt@sun.ac.za>]

Hi,

I'm struggling to sync two Delta 1010LT cards. I've tried both the word 
clock and SPDIF approaches, without any success. Both the SPDIF Out and 
Word Clock Out connectors show no activity when inspected by an 
oscilloscope.

Questions:

- Is the word clock output something you must switch on in the ALSA 
driver or is it supposed to start automatically when you have a valid 
clock signal on the card?

- Do I have to do something special to get SPDIF output (I'm new to 
this)? I've fiddled with iecset from alsa-utils, and otherwise I 
connected the SPDIF Out to various inputs using the patchbay of 
envy24control. Still, no signal appears on the connector.

If it helps, here is /proc/asound/card0/ice1712:
