HDMI audio for "X1200 Series Audio Controller" - unsupported encoder type 0x19

[Igor Katson]

Hi,

I have a pretty old laptop — ASUS A7U, and it has the following ATI hardware:

01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee
ATI RS690M [Radeon X1200 Series]
01:05.2 Audio device: Advanced Micro Devices [AMD] nee ATI Radeon
X1200 Series Audio Controller

The problem is, that I cannot hear any sound when using HDMI audio,
though I can see the device.

My system is up-to-date ArchLinux.

I've tried everything found on in the internet, including:
- added radeon.audio=1 to the kernel boot line
- tried searching for HDMI settings in BIOS, but did not find any
- installing 3.3 kernel

I can see the HDMI device both in Pulseaudio GUI and in
aplay/alsamixer. Here is my aplay -l output

This command has no errors, but no sound either:
aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav

Here is the output of "dmesg | grep radeon"

I think that "Unsupported encoder type 0x19" has something to do with
the problem.

Thanks for any help and answers!
