          Priority: medium
            Bug ID: 62040
                CC: lennart at poettering.net
          Assignee: pulseaudio-bugs at lists.freedesktop.org
           Summary: Echo canclled sink is mono
        QA Contact: pulseaudio-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: cloakable at fennec.org.uk
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: modules
           Product: PulseAudio

Running: "pacmd load-module module-echo-cancel" creates the source/sink, but in
mono only, despite running on a stereo source/sink. Testing reveals that
anything played through that sink (and therefore echo cancelled) is playing in
mono...

Running "pacmd load-module module-echo-cancel channels=2" silently fails.

This is a major problem for me; I plan on eventually running 5.1 speakers +
mic, but if the echo-cancel module is just going to squash that into mono the
entire setup will be useless.
