Hallo:

I've bought a laptop HP Pavillion DV6 2026es.

I'm trying to connect it to the TV with HDMI, but the sound is not transmitted.

This is what I have:
root@ubuntu:~# cat /proc/asound/cards
0 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xf2400000 irq 16
1 [HDMI ]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0xf2310000 irq 31

I'm trying it with Kubuntu 9.04.

Can any tell me what do I have to do for transmitting sound over HDMI?

Thanks

You need to configure it in PulseAudio, use pavucontrol to change the output device. Install the pavucontrol package if it's not installed.

I've installed it and running it, it says that the file or directory does not exist.

ubuntu:~$ pavucontrol

(pavucontrol:2698): GVFS-RemoteVolumeMonitor-WARNING **: cannot open directory /usr/share/gvfs/remote-volume-monitors: Ha ocurrido un error al abrir el directorio «/usr/share/gvfs/remote-volume-monitors»:·No existe el fichero ó directorio

The most strange is that the directory really exists:


ubuntu:~$ ls /usr/share/gvfs/remote-volume-monitors -l
total 8
-rw-r--r-- 1 root root 123 2009-10-20 05:57 gdu.monitor
-rw-r--r-- 1 root root 115 2009-10-20 05:57 gphoto2.monitor


Any other suggestion?

Ignore what ongte have stated because pulseaudio is not the only way and I do not recommend this way.

Digital audio in Linux is not reliable. I suggest use a media program to only output digital audio instead all the time. To do this in mplayer use the following.

mplayer -ac hwdts,hwac3,dvdpcm, -channels 2 -ao alsa:device=hw=0.1 dvd://

or

mplayer -afm hwdts,hwac3,dvdpcm, -channels 2 -ao alsa:device=hw=1.0 dvd://

or

mplayer -ac hwdts,hwac3,dvdpcm, -channels 2 -ao alsa:device=hdmi dvd://

or

mplayer -afm hwdts,hwac3,dvdpcm, -channels 2 -ao alsa:device=hdmi dvd://

The dvd:// is just an example file. If you want to output digital audio all the time, you have to edit $HOME/.asoundrc to format the audio in a proper way for the TV to accept the audio. If the TV is HDCP compliant, the possibility of audio playing from digital from a computer is slim to none or you are shit out of luck. For me on a AMD 780G, digital audio over HDMI does not work in a reliable way. It only worked sometimes and I am just being nice. It might have improved, but I suggest use analog audio.

I understand pulseaudio has it's problems. Until just recently PulseAudio has been pretty shite.
Maybe I'm a lucky one but PulseAudio has worked quite well for me. I'm running Mandriva 2010 & I regularly use PulseAudio to switch output devices on my audio streams on a per application basis.
For example. When listening to Music with Amarok, the audio goes by default to my Bluetooth Headphones.
When playing video with SMPlayer, I can set it to output to my Dell LCD monitor through the HDMI port & it comes out of the monitor's built-in speakers. (It's not a TV though, so you're right about the HDCP problem)

I gotta hand it to the Mandriva guys. They have the best PulseAudio implementation I've seen so far.

I've installed OpenSuse 11.2, installed ATI driver, places HDMI as first device in preferenes-multimedia and now it works fine.

Thanks
