PostPosted: Tue Jan 14, 2014 3:41 am    Post subject: HDMI audio issues Reply with quote

I am running gnome 3.10 with pulseaudio and alsa. I have disabled all other audio codecs in the kernel besides the required HDMI one. I have two AMD Radeon HD 7850's crossfired. I have a Dell ST2421L. Whenever I try selecting the HDMI audio option in the gnome control center, I get no sound.

here is lspci -v:

Those who have been able to have sound through HDMI should help us here. I never been able to have it myself. I read that Linux do not support all audio devices through Hdmi. I read too that Linux kernel parameters
Code:
radeon audio=1 tv=1

should be activated to have it. Even if Alsamixer and Pavucontrol show an Hdmi entry, I have no sound. I dont think you need to disable all Alsa support but Hdmi to have sound with it.
Code:
00:01.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Trinity HDMI Audio Controller [1002:9902]

first you need:

Intel HD Audio --->[*] Build Realtek HD-audio codec support and
Intel HD Audio --->[*] Build HDMI/DisplayPort HD-audio codec support

in the kernel

2:

mybox linux # lspci -k
09:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Cayman/Antilles HDMI Audio [Radeon HD 6900 Series]
Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Cayman/Antilles HDMI Audio [Radeon HD 6900 Series]
Kernel driver in use: snd_hda_intel
Kernel modules: snd_hda_intel
3:

mybox linux # emerge -av pavucontrol
hese are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild R ] media-sound/pavucontrol-2.0 USE="nls" 149 kB

Total: 1 package (1 reinstall), Size of downloads: 149 kB

Would you like to merge these packages? [Yes/No]

4:open pavucontrol.go to configuration,activate the profiles you want,start a song or movie and see if you get a sound on the hdmi at the output devices tab.

I double what hedmo said. You can try emerging pavucontrol first, and maybe it will show you that you already have the correct kernel drivers and the device is detected correctly. Then you should check if the correct profile is selected.
If there is no sound yet, you should check alsamixer. You probably have a muted digital output (SPDIF).

Don't forget to select the correct audio card on alsamixer.

Hi

Sometimes it is also necessary to add: audio=1 to /etc/conf.d/modules radeon driver.
