i took out my opus dac and fired her up again and for some reason, am not getting any sound via the optical connection. usb works fine, but once i switch to toslink, no sound. my imac recognizes the toslink. but on the receiver module, only one of the led lights is green. the others are red. i'm guessing that it's not detecting the optical signal, but i can't figure out where in the chain the problem is.
this opus dac was built for me a while back and i guess i've only used it via the usb but thought i'd try the optical, only to find that it's not working. i'm using the older v. 1.0 dac board. and the v 1.1 receiver module.
the connections go like this:
usb -> I2S -> OTTO -> metronome -> DAC/ballsie -> SE and balanced outputs
toslink/coax -> SPDIF ->receiver -> metronome -> DAC/ballsie -> SE and balanced outputs
i've tested the security of the connections and they're all fine. i've not tested the electrical connections w/ a multimeter yet. that's next...
the question is, USB input works fine, but when i switch to toslink, there is no sound. so, where in the chain should i check? i'm assuming the toslink connector and the receiver are the first culprits, right?
all the dip switches are per the recommended stereo configurations given by twisted pear. any suggestions would be welcome. thanks.
the receiver module. only the non-audio LED is green. others are red.
