            Bug ID: 792897
           Summary: wasapi: Implement multichannel support and a device
                    provider
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: All
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: nirbheek.chauhan at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Despite the rewrite in commit 145085109, multichannel support was missing in
both the WASAPI source and sink elements. It should hopefully work with these
patches, but I have not tested anything beyond mono and stereo because I do not
have any multichannel devices.

The second patch implements a probe-only device provider for the source and
sink elements. This has been tested and works quite well. Note that WASAPI does
not handle device state changes for clients transparently, and these elements
do not implement device hotplug yet. Hence, device monitor support is also
missing right now.
