Description pht 2013-10-06 15:32:31 UTC 
Hello

I have

01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RS880 [Radeon HD 4200]
01:05.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] RS880 HDMI Audio [Radeon HD 4200 Series]

And I boot with radeon.audio=1

In previous kernel (3.10), sound works. With kernel 3.11 I can't hear the sound. The card is listed in alsamixer, and output is unmuted, but I can't simply hear the sound. Downgrade of kernel and reboot fixes the issue.

RS880 is a DCE 3.0, you may want the following fix:
drm/radeon: fix hdmi audio on DCE3.0/3.1 asics

Please try 3.11.4 which includes it and report back.
