Hi

If I plug the optical cable into the audio port I get the digital output option in preferences/sound but I get no sound and I get no light in the cable or port?

If anybody has any ideas they would be much appreciated.

thanks
Nigel.

Depending on the application you might have to also select digital out from the preferences. Maybe giving more details about what you are specifically trying to do would help?

Trying to output music (from itunes library currently) thru the optical out on airport express into a schitt modi 2 uber and from there into stereo.

Can't get it to work thru the express so was trying to get it to work from the laptop optical out first. But no joy.

I can get the laptop to the dac via usb fine but that isn't what i want as i need it to be wireless.

the dac shows up in the audio midi panel if connected via the usb but not the optical cable if that sheds any light on the problem?

at this stage testing all components with known working to figure out where the problem is

Further to this

Have now tested with known working dac and cable still no signal so I can only assume that I'm getting no digital output from the mac book pro or the airport express.
