AV-reciever doesn't work with DIT4096

[Korr]

I've made an optical output based on DIT4096 from my car stereo. It works fine with Sven Home theatre anâ PC soundcard. ut my home Yamaha AV-Reciever. It isn't shwn on the rciever display that it gets PCM sygnal and keep silent. DIT4096 is in PRO mode, PCM. Where is the problem?

Maybe double-check that it's set for S/PDIF, not AES? Maybe the voltage output is marginal?
