Thinking about it some more, I am guessing you mean that the Front and Master channels may be intentionally linked together. I was thinking of "Front" as meaning the center channel of a surround sound system but I see there is a separate channel for that so I assume it means the headphone jack on the front of the case. So yes, it would indeed usually make sense to make "Master" and "Front" synonymous.
However if this is the case, then the bug would be that if muting one mutes both then unmuting one should also unmute both which isn't happening. It looks like I did not explicitly mention this detail in my first post but if I mute Front (which also mutes Master) then unmuting Front does NOT unmute Master. And of course point c) from my original post also remains. -- Sound mixer problems with Realtek ALC889A https://bugs.launchpad.net/bugs/439779 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
