Sound works on DVI-0 but does't work on DVI-1. I know it works, because it works on Windows and also works with the fglrx driver. The radeonhd driver offers a configuration option for which DVI to output sound, and i could not find a similar option on the radeon driver or on the radeon kernel module. My configuration: DVI-0 has my LCD monitor, and DVI-1 has my plasma TV with the ATI DVI-to-HDMI connector. If i switch the configuration and plug the TV on DVI-0, sound works. I recommend to make sound output on both connectors by default, if possible. driver version: 6.13.99 git 20100407 kernel version: 2.6.34-rc3 x.org X server version: 1.7.6 git 20100407 lspci: 01:00.0 VGA compatible controller: ATI Technologies Inc RV630 [Radeon HD 2600 Series] 01:00.1 Audio device: ATI Technologies Inc RV630/M76 audio device [Radeon HD 2600 Series] aplay -l: **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0
Please, wait for 2.6.34-rc4 and try it when it's released. In case it still won't work for you, provide output of dmesg | grep drm as good beginning.
I have just tried with kernel 2.6.34-rc4 and it still does not work (i didn't see any audio fixes on the 2.6.34-rc4 changelog).

Created attachment 35857 [details] Xorg log for the attached log i am using and older stable version, but it works the same way (sound works, but only on connector DVI-0).
Tried on the 2.6.34 final, still does not work. This is annoying because the setup is usually a monitor on the first connector and the TV (which uses HDMI audio on the second). I can switch the connectors without any major problem, but this is not the best configuration. Some apps do not respect the primary monitor configured on xrandr and insists on opening on the TV.
