[HELP] Radeon HDMI Audio Not Working

TKH · 07-27-2015, 02:47 AM

Sound works just fine on the analog audio. But it won't work over HDMI, even with 'radeon.audio=1' boot option included.
I tried all I can (tested the output, switched around master channel, adjusting volumes, switching speakers/headset even), but I cannot get it working.

My system:
OS: Fedora 22, Linux 4.0.8-300.fc22.x86_64
CPU: AMD A10-7850; RAM: 16 GB
GPU: AMD R7 Dual Graphic; VRAM: 1 GB
Audio: Radeon HD 7700/7800 Series

Any word would be appreciated!

Check aplay -l to get device listings & create an .asoundrc file.

Quote:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC262 Analog [ALC262 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0

You can edit mine as needed

$ cat .asoundrc

Hi:

I had trouble with sound recently too.
I ran this in the terminal to discover that I had 2 sound cards.

Code:

cat /proc/asound/cards

Sometimes installing pavucontrol helps. In the configuration section you can set the card that you want to use among other settings.

Hey,

I had issues with the audio going 2x speed when I connected a 4k TV at 60Hz to my radeon 480 on Manjaro.
Installing pavucontrol fixed the issue.
Thanks a lot!
