            Bug ID: 80162
          Assignee: dri-devel at lists.freedesktop.org
           Summary: center and lfe channels screwed up on suspend
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: pierre-bugzilla at ossman.eu
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: DRM/Radeon
           Product: DRI

Started out in the kernel bugzilla as I figured this was an alsa driver
problem:

https://bugzilla.kernel.org/show_bug.cgi?id=77901

> AMD HDMI audio output. Works fine until I suspend the machine. After resume, center channel is silent and LFE channel is sent as center.
> 
> Massive issue as the center channel is the most used one of all in multichannel audio sources. :/
> 
> Unloading just snd_hda_intel and reloading it seems to work around the issue.

The verdict there though was that it didn't seem like the audio end was doing
anything wrong, so it must be something in the graphics driver.

Help?
