|

Hi folks. I've got this strange problem.
I don't hear a sound coming out of my TV when I connect it to my Laptop running Gentoo with a 3.6.11 Kernel. An HDMI cable is used. So no DVI Adapter but HDMI to HDMI. I am using radeon driver kms.
X Server 1.13.1 recognizes the screen and uses it beautifully to display my desktop.
Code: | [*] Build HDMI/DisplayPort HD-audio codec support |
is set in the kernel.
Code: | # lspci
01:00.1 Audio device: Advanced Micro Devices [AMD] nee ATI RV710/730 HDMI Audio [Radeon HD 4000 series] |
Code: | $ aplay -l
Karte 0: Intel [HDA Intel], Gerät 0: ALC888 Analog [ALC888 Analog]
Sub-Geräte: 0/1
Sub-Gerät #0: subdevice #0
Karte 0: Intel [HDA Intel], Gerät 1: ALC888 Digital [ALC888 Digital]
Sub-Geräte: 1/1
Sub-Gerät #0: subdevice #0
Karte 1: HDMI [HDA ATI HDMI], Gerät 3: HDMI 0 [HDMI 0]
Sub-Geräte: 0/1
Sub-Gerät #0: subdevice #0 |
So I try
Code: | # aplay -D plughw:1,3 /usr/share/sounds/warning.wav
Wiedergabe: WAVE '/usr/share/sounds/warning.wav' : Signed 16 bit Little Endian, Rate: 44100 Hz, stereo |
It seems to play but I don't hear a thing.
I've set
/etc/default/grub
Quote: | GRUB_CMDLINE_LINUX_DEFAULT="radeon.audio=1" |
I am using pulseaudio and emerged media-sound/pavucontrol
I've set the VLC Player to the HDMI output and the output is recognized (the blue bar represents the sound that is being put out) but I can't physically hear it.

It works with windows so the hardware shouldn't be at fault.
Any ideas what's left to try? _________________ "Linux basiert doch auf DOS oder nicht?" *schüttel* |

HDMI/DisplayPort HD-audio codec support might not be enough, can you post the entire relevat alsa section? _________________ Only two things are infinite, the universe and human stupidity and I'm not sure about the former - Albert Einstein |
