Priority: medium Bug ID: 70176 Assignee: dri-devel@lists.freedesktop.org Summary: Radeon audio over HDMI doesn't work (kernel 3.11.1, 3.12 rc3) Severity: normal Classification: Unclassified OS: Linux (All) Reporter: dennisridder@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI

Hello,

I have tried to get audio over HDMI working with two of the latest kernels, adding radeon.audio=1 in GRUB.

Kernel 3.11.1 (as supplied on XBMC forum with several patches incl. HD audio related ones): No message of audio being enabled in dmesg.

Kernel 3.12 RC3 reports back: [drm] Enabling audio 0 support [drm] Enabling audio 1 support [drm] Enabling audio 2 support [drm] Enabling audio 3 support [drm] Enabling audio 4 support [drm] Enabling audio 5 support

The devices and cards are detected and listed with "aplay -L", unmuted every channel through alsamixer. I tried getting noise out hitting "aplay -D (plug)hw:0,3" but physical sound is not being produced.

I already tried "xrandr --output HDMI-0 --set audio auto" (or "on", "1", etc)

As a reference, everything is working with the Catalyst drivers, so it's not a hardware flaw.

Uncensored dmesg logs: http://paste.ubuntu.com/6196722/ http://paste.ubuntu.com/6197292/

Please help! Let me know if you need more information from me to get to the bottom of this.

P.S. I am having this issue together with screen artifacts in XBMC, for which I will file another bug.
