i am outputing s/pdif from this card to a dac.

under the "H/W out s/pdif tab" in the patchbay/router section of m-audio's control panel, i must chose "monitor mixer" if i want asio output to work in foobar. if i chose "wav out s/pdif", i get silence. is anything taken away or modified from the s/pdif siganl by chosing "monitor mixer"?

the only way i can get the "wav out s/pdif" option to work is if i chose "waveout" in foobar, but then i am not sure if asio is working.

is it ok to use monitor mixer?

If you use the monitor mixer you run all the bits through the cards mixing engine.

In the output plugin for whatever player you are using you will find there is a paramter called channel shift or offset. Try increasing the value by 2 until you get the sound routed through the S/PDIF interface.

Cheers

you are a genius.

it works now using wavout spdif. if i now select monitor mixer, just for the hell of it, i only get sound out of the right channel. i dont need to do this, but i am curious as to why this is.

any idea?

thanks again :)

btw, i called m-audio and they claimed that by running the spdif through the mixer the bits are not altered at all unless you attenuate. do you find this to be true? i wasn't completely sold by the tech support guys claim, though. he said as long as i'm hearing sound i'm ok!

I have never tried whether routing bits through the mixer is bit transparent but I do not use it for another reason.

I have my Windows sound profile set to No Sound but since that does not really suppress all sounds I also have the Windows sound device set to the analog outputs. If you get your S/PDIF out via the monitor mixer you end up with the Windows System sounds intermixed with the music playback. I wanted to have those really separate.

Cheers
