Issue with HDMI audio output

Hello everyone,

this is my first post in Arch Linux forum. I am a Newbie but have always managed to work things around with ArchWiki documentation, but I am having an issue I could not solve for some time now.

My HDMI audio output was working fine, but stoped working about a month ago, maybe due to some update. I use the open source ATI driver (xf86-video-ati package), and enabled the kernel parameter radeon.audio=1, like it is documented.

My graphics card is a Radeon HD 3650. I checked for the compatibility of the driver (http://www.x.org/wiki/RadeonFeature/#De … ting_names) and it seems to be ok.

Do you have any suggestion to help me?

Thank you in advance

Re: Issue with HDMI audio output

Output of "aplay -l"?

Do you use pulseaudio? If so, what is the output of "pactl list"?

Thank you for your reply

Here is the output of aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC268 Analog [ALC268 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC268 Digital [ALC268 Digital]

  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1

No, I do not use pulseaudio.

Re: Issue with HDMI audio output

Yeah I did.
When I play a sound to the HDMI card there are no errors displayed but I cannot hear anything...

Here's the output:

$ aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

Re: Issue with HDMI audio output

Anything odd in the journal?

What does "amixer -c 1" say?

Re: Issue with HDMI audio output

So the HDMI output is detected properly by ALSA, it is unmuted, and there are no errors when trying to use it... I read in another thread that somebody with a similar issue got it to work by reinstalling the xf86-video-ati package. Might be worth a try.

If that doesn't work somebody else has to chime in with suggestions.

Re: Issue with HDMI audio output

Well I did unistall xf86-video-ati and tried xf86-video-ati-git from the AUR. Didn't know if that would work out but I gave it a try. I still couldn't get the HDMI sound working. So then I reinstalled xf86-video-ati, and still no sound.

Many thanks for your input.
I hope somenone has more suggestions

Re: Issue with HDMI audio output

There is another thread here:
https://bbs.archlinux.org/viewtopic.php?id=171236
Which might be the same issue.

(Same suggestion here: Maybe try the LTS kernel?)

Hello everyone,
I have not been around the last couple of days, but it seems that after the last update the problem was solved, just like Edward reported.

Many thanks for your help
