Hi, I'm trying to get audio working on my Radeon HD 4350 via HDMI. My audio was working previously with the fglrx driver, but due to unrelated stability issues with that driver, I'm giving radeonhd a shot. I'm running the latest Git revision of the driver on Arch Linux x86 with the 2.6.30 kernel & KDEmod 4.2, if that's relevant. I saw that support for HDMI audio on R700 chipsets (the 4350 is one of them) was added fairly recently, but didn't see anyone having mentioned getting it to work on the 4350 in particular. Can anyone confirm that it is indeed supported? Anyway, this is what I know so far: 1. My xorg.conf includes the ``Option "Audio" "on"'' and ``Option "HDMI "all"'' settings. 2. ``aplay -l'' includes this output: card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 3. KDE recognizes the ATI HDMI sound device, and has it set as the preferred audio device for all output. 4. alsamixer has both columns unmuted. The ``PCM'' column is set to ``100<>100'', while the ``IEC958'' column is set to ``OO''. KMix doesn't show a volume slider for the HDMI audio output, but it is unmuted. 5. My ~/.asoundrc contains: defaults.ctl.card 1 defaults.pcm.card 1 defaults.pcm.device 3 6. I also ran alsaconf (as root) after changing the driver from fglrx to radeonhd. 7. This is what happens when I try to play an audio file with aplay: $ aplay -D hw:1,3 /usr/share/alsa/speaker-test/sample_map.csv Playing raw data '/usr/share/alsa/speaker-test/sample_map.csv' : Unsigned 8 bit, Rate 8000 Hz, Mono aplay: set_params:979: Sample format non available 8.
