[LAU] MAudio Delta, s/pdiff and external a/d converter - trouble

Hello everyone! So I got my A/D converter today. I connected everything - correctly I assume and I get no sound, although I can see a small red light issuing from the A/D. If that is any help, it's a Lindy analogue digital converter. There wasn't much more as a name. I connected it to the in0 digital port, one of the calbes with RCA jacks on the smaller breakout cable, the one with the MIDI jacks. I also shut down the system and rebooted, in case the A/D needed any sort of synchronisation from the card. Nothing. I checked alsamixer (not being able to use a GUI mixer). All volumes are up, almost everything is unmuted. Both spdiffs are routed to pcm out, but I tried the rest as well. Nothing. I tried to use it by connecting the jack ports: system:capture_9 to 12 with system:playback_1 and 2. Am I doing something fundamentally wrong? Is there an oversight? Or does that hint at a broken device? Warm regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html
