I've got a Radeon HD3870. As you can see on the picture, it has two DVI outputs.
The strange thing is this (output of lspci):
Three questions:Code:05:00.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3870 05:00.1 Audio device: ATI Technologies Inc Radeon HD 3870 Audio device
- Is there a seperate audio chip on the videocard?
- Can I convert my DVI to HDMI with audio?
- Why doesn't Pulseaudio recognize this 'Audio device'?
according to Wikipedia DVI doesn't support audio signals and probably DVI to HDMI will only carry Video signal
i can only guess that you see the audio device because the chipset supports sound over HDMI/Displayport but you have only DVI output
except if the makers of the card use some non standars DVI that allows DVI with sound -> HDMI
DVI and HDMI have the same pin[s]g[/s]s. I'm absolutely sure you can play audio using DVI to HDMI adapter connected to GPU, and then using HDMI cable. I'm doing that myself using RV635 with two DVI outputs.
I'm just not sure if using direct DVI to HDMI cable or DVI cable and DVI to HDMI adapter before monitor input will work. I think it should but didn't test.
Not sure about PulseAudio, but you can try mplayer and alsa for this. First of all check output of aplay -l. Look for HDMI:and then use:Code:card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0Just make sure you use radeonhd 1.2.5 andCode:mplayer -ao alsa:device=hw=1.3 file.flacCode:Option "HDMI" "DVI-I_"

You've been reading Wikipedia quite wrong.

Thanks nanonyme, I'll check the latest version of Pulseaudio, since I don't want to bypass Pulseaudio by using Alsa.
