I can also confirm this bug in Intrepid as muting and unmuting the master channel does not affect the sound.
When the mute /unmute button is pushed the volume that shows up under master channel remains at the same level, with a mute symbol yet the sound remains the same. I also get a crackling noise when I mute the PCM channel. -- Muting Master channel doesn't mute sound https://bugs.launchpad.net/bugs/93600 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
