Interesting, alsamixer can't mute/unmute PCM, but it can mute/unmute other controls like Master and LFE.
Please look attached screenshot: Master and LFE have a square with "00", which turns to "MM" when muted (like IEC958). PCM doesn't have this square, and pressing "m" to change muted state has no effect in this control. ** Attachment added: "alsamixer" http://launchpadlibrarian.net/17781373/alsamixer -- "Mute/unmute PCM" button doesn't unmute audio https://bugs.launchpad.net/bugs/272336 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-media in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
