Package: audacity
Version: 2.2.0~pre4-1+b1
Severity: normal
Dear Maintainer,
This has been happening even in the 2.1.X "stable" versions of VLC.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Going into Audio -> Stereo Mode -> Left/Right
* What was the outcome of this action?
Choosing any of those two doesn't do anything, VLC still plays both
channels regardless.
* What outcome did you expect instead?
To have either the left or the right channel to be duplicated, and the
other to be discarded.
Here's the log of what was printed in the message window while trying to
use this feature:
