Priority: medium Bug ID: 80162 Assignee: dri-devel@lists.freedesktop.org Summary: center and lfe channels screwed up on suspend Severity: normal Classification: Unclassified OS: All Reporter: pierre-bugzilla@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?
