The good news, I had the time to test S/PDIF out today with one of my Envy24 cards, the bad news, I wasn't able to get S/PDIF out working. With a TerraTec EWX24/96 I tested Envy24 S/PDIF optical out -> Sony DTC-670 S/PDIF optical in With and without Sony DTC-670 S/PDIF optical out -> Envy24 S/PDIF optical in mhwe outL -> jkmeter in-1, playback_1, 3, 5, 7, 9 mhwe outR -> jkmeter in-2, playback_2, 4, 6, 8, 10 $ mudita24 -v -c1 $ envy24control -v -c1 Digital in works, analog out works, but I don't know what to do, to get digital out working. JFTR I don't know if the DAT recorder's optical S/PDIF in is ok. If it should be possible with Linux to set my RME HDSPe AIO ADAT IOs to become S/PDIF IOs (the manual says it's possible when using Windows), I could test if the Sony in is ok, or simply connect an Envy card to the RME card.
