I'm trying to get KMS and HDMI audio working on a 4350. All I see in alsamixer is an S/PDIF device that you can't set the volume on. I'm running Linux 2.6.33 RC6. I'm starting the kernel with...
My understanding is that with KMS enabled I don't need to have X loaded.Code:kernel /kernel root=/dev/sda5 radeon.modeset=1 radeon.audio=1
It didn't work without KMS and RadeonHD, either.
I have it working with a Radeon HD 4670. Didn't had any problems. Whats the output of cat /proc/asound/cards and lspci -nv?

Unfortunately the ALSA driver only supports 2 PCM channels :(.Code:01:00.0 0300: 1002:9490 (prog-if 00 [VGA controller])

oookkkaaayyy... It seems as if KMS doesn't support audio output on the RV710 and RV730. Does anyone know when ATI's KMS will be updated to support audio on this series?
