Under openSUSE 11.1 how is it possible to use the audio output via HDMI? I see in the mixer "HDMI Audio" but no sound output is produced. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That "HDMI Audio" was provided by your videocard, I guess. Becuase I get one, too. But I never used it. It's output is sent to the HDMI port of the videocard, you can't get the output from the audio output port. Sorry for my bad English. -- Regards Yang Bo -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It depends on hardware. HDMI over ATI graphic board should work with fglrx driver. IIRC, HDMI on radeonhd came after 11.1 release. On Factory, it should work. HDMI over Intel graphic isn't supported on 11.1. On Factory, it could be, but not sure. The XOrg:Devel repo should work, though. In general, X has to run to enable HDMI output, because the HDMI is a composed output of both graphic and audio, and the graphic driver has to cooperate with the audio part in some role. Also, note that the way to choose HDMI output depends on the hardware implementation. In some cases, you'll have an individual HDMI output audio device, and in some cases, HDMI is bundled together with the normal analog output. That is, the hardware implementation of HDMI is very chaotic right now...

Is there any documentation on HDMI audio with fglrx? On Mon, May 4, 2009 at 09:09, Takashi Iwai <tiwai@suse.de> wrote:

It might be worth while having a read of this wiki entry on MythTV although I believe it is for a debian based system. http://www.mythtv.org/wiki?title=AllensDigitalAudioHowto -- Regards, Graham Smith -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That seems perfect, except I have no /etc/asound.conf file. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
I have it working now, disabled audio in the BIOS (yes, disabled audio in the BIOS), I don't think that was needed but the onboard audio chip is not used when using HDMI, I then created /etc/asound.conf and issued the command rcalsasound restart. pcm.!default { type plug slave { pcm "hw:0,3" format S16_LE } } Also works: pcm.!default { type hw card 0 device 3 } Basically match what aplay -l shows for your card. S16_LE I got from the output of: speaker-test -c2 -D plughw:0,3 -twav -l1 That command worked and played a speaker test even without any configuration, which reinforces my theory that something just had to be configured to tell ALSA to output sound to that particular device. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
