Optical SPDIF via 3.5mm Jack?

[djanssen]

Why would you want a toslink if there is spdif? Looking at tests the quality of toslink is not beter than spdif. Maybe a coaxiaal interface would be great, otherwise extract digital audio from HDMI.

Agreed with Mischa, Hifi folks use coaxial for higher sampling rate and bit resolution. We have start design a board that try to archive 192KHz, 24 bit out at coaxial. It is kind of funny, that copper cable better than optic fiber on this case.
