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. This is what happens when I try to play an audio file with MPlayer:
$ mplayer -ao alsa:device=hw=1.3 /usr/share/alsa/speaker-test/sample_map.csv
MPlayer UNKNOWN-4.4.0 (C) 2000-2009 MPlayer Team

mplayer: No such file or directory

Playing /usr/share/alsa/speaker-test/sample_map.csv.
Exiting... (End of file)

9. /proc/asound/HDMI/pcm3p/sub0/info contains:
    card: 1
    device: 3
    subdevice: 0
    stream: PLAYBACK
    id: ATI HDMI
    name: ATI HDMI
    subname: subdevice #0
    class: 0
    subclass: 0
    subdevices_count: 1
    subdevices_avail: 1
While I play an audio file with MPlayer, /proc/asound/HDMI/pcm3p/sub0/status 
contains:
    state: RUNNING
    trigger_time: 32317.502694751
    tstamp      : 32318.546675126
    delay       : 15722
    avail       : 662
    avail_max   : 662
    -----
    hw_ptr      : 46040
    appl_ptr    : 61762
When the playback ends, it just says ``closed'', so clearly something is being 
played back.

Thanks,

Samir Unni
