Just got my Chaintech AV710 last week. Installed the latest 3.10A driver from VIA website and really impressed by the analog output through the Alt port using "high sample rate" mode.

But have a problem with the optical output of this card. I cannot get any signal from AV710 when connecting it with my MD recorder via Toslink cable. If I disable AV710 and use my onboard card as default, everything is ok i.e. MD recorder easily detects the optical output from onboard card.

Anyone has ideas how to make the AV710 optical output work? Thanks a lot.

IIRC optical out does not work in hi-res mode.

I also tried the ordinary 2 channel mode, still no output.

Do you see any red light out of the end of the toslink cable? Make sure that the digital out is enabled in the Via Envy Control Panel.

Yes. I can see red light coming out of the cable. And I can see the S/PDIF signal meters in the VIA control panel. All seems ok, but just no physical output.

Check the control panel to see what sampling rate its outputting at, make sure its 44100hz. I used the AV710 once with a MZ-N505 and it was OK.

Maybe my AV710 is a defected one? I gave it up. Will wait for my recently ordered Prodigy 192 to see whether S/PDIF works. Thanks anyway.

If you only plan to use the optical out, you can flash it into a prodigy 7.1 (see thread http://www4.head-fi.org/forums/showthread.php?t=75844).

When you're in the high res mode everything is resampled to 96KHz, including the digital out. Turn off the high res mode and see if it works then.

I tried the ordinary 2 chennel mode which is set to 44.1K output and enabled the Digital Output with PCM. I can still get the analog output through 7 and 8 phone jack but no optical signal through Toslink.
