newbie has silent audio disc
The best app I think on 64Studio 1.0 for playing an audio CD is Sound Juicer, but I get silence. I've tried Alt+F1 | Desktop | Preferences | Multimedia Systems Selector but with even with the test bar running back and forth I still get silence. With Linux Mint (dual-booted on same hardware) I get the 'oooo' tone when I've successfully set it up. I tried this Multimedia Systems Selector tool with JACK off and on.
The only noise I have been successful so far with is ZynAddSubFX through JACK, and Rosegarden playing through ZynAddSubFX through JACK.
Soundcard? M-Audio 2496.
Yes, it did take me three weeks to get a sound out of Cubase back in 2002. Why do you ask?
