I have an Asus M3N78-VM MB with on-board sound only. In trying to debug overloading of signals using Audacity I found that the line input produces a full undistorted signal at about 42mV RMS (~115 mV P-P), and clipping at much above that. These values are confirmed with Fluke 87 and a Tek scope. The clipping shows up in Audacity. The web indicates that consumer audio line level signal should be 894 mV P-P, and my stereo receiver seems to agree that this value is the correct order of magnitude.
My MB manual says nothing about what they think line-level is, and Google did not enlighten me about this type of problem with the MB. I see no hardware switches on the MB nor anything in the BIOS. Anybody have ideas? Thanks, -Denis _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
