Comment 1 for bug 713078

This has been discussed in the past (not necessarily in a bug, may have been irc or email) but this is necessary for both mono outputs (a requested feature) and microphone inputs (a roadmapped feature). For example, if a user's mic in is channel 1 on the sound card and then has a stereo line in as channels 2 and 3, this fine-grained selection is necessary.

In regards to user confusion, the user will get the following error message in a dialog when he selects overlapping channels: "Two outputs cannot share channels on sound device "default"", giving the user the problem and where to look to solve it (at all the outputs with the "default" device selected).

This has been in the wild since the 1.9 beta was released, have there been significant issues reported? There hasn't been a bug that I've seen until now and the beta has been out for months now and seems to be widely used.
