Hi,

I have a Scientific Atlantic digital cable box and would like to use the digital audio out to go into my new Yamaha RX-V1400. When connected, I am not getting any output from the jack. I tried my upstairs box and got the same result. The analog RCAs work fine. I was also sure to enable the digital out in the box's setup menu.

I have a multimeter. Is there a way I could measure the output of the jack? How, and what readings would I expect if it was working? And, what readings should I expect if it's not?

Thanks,

Mark
