But, in that thread, it appears that audio is still making it through if not in sync. It seems in this case there is not even audio. This is what puzzles me. It seems audio can go one way but not both. However, to test it (quoting from the above thread) "I just grabbed an old Ubuntu 10.04 ISO which contains Alsa 1.0.22 and live booted it on my machine. Tests show that it's working as expected with the 1010LT: It's properly externally clocked." This would be the Ubuntu 10.04, not ubuntustudio which was not a live ISO back then. This means no jack while running live unless you have tons of memory and wish to install it while running live :) But pulse should be able to be set to the spdif i/o. I am also not sure envy24control would be installed by default (alsa-tools-gui) but alsamixer is there. Alsamixer can set the sync to spdif with the rate setting (96000 + one). Should be able to see if it is possible while running that ISO to run audio from linux - 1010lt to 9624 and back. Use the multi mixer feed the return spdif audio to analog 1/2 outputs. -- Len Ovens www.OvenWerks.net
