Hmm, just changed sound with alsamixer -Dhw:0 Master slider a bit and now the distortion disappered... it's now as clean as with speaker-test -Dsurround51.
Somebody on ubuntuforums.org wrote that you can reproduce the distortion if you touch the fade or subwoofer slider on the output tab in the sound preferences dialogue. I confirm this behaviour. If I move the sliders back into their original position, the noise disappears again. forum post: http://ubuntuforums.org/showpost.php?p=8290572&postcount=13 -- volume control causes high pitched distortion https://bugs.launchpad.net/bugs/466936 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
