The audio plays normally in stereo on the speakers. ====================================================================== ---------------------------------------------------------------------- Matthias Koenig - 01-13-06 14:29 ---------------------------------------------------------------------- I have the same symptoms on my system: Capturing Line, works only on channel 1, channel 2 is silent, although with some noise. I figured out that switching the Mic Boost on changes (boosts) the noisefloor of the silent channel 2. Some tests with a Microphone confirmed that channel 2 records always the Mic input, independently of any capture source settings in mixer. Switching Capture off in mixer does work (silence on both channels without noise). However, switching capture source is only effective on channel 1. Channel 2 keeps listening to Mic input.
