[solved] HDMI Sound

Postby kruijf on Fri Dec 09, 2011 8:04 am

I want to use my HDMI on my Dell inspiron 1525, how do i get the sound working.
One time i had sound whit VLC, but is it also possible to get the sound from your browser (chrome) whit HDMI?
This is my grub:
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""


Must i do the same as in this topic: http://forums.linuxmint.com/viewtopic.php?f=196&t=79777&p=464007#p463780 ?

I am not an expert on your machine but I had to run through a lot of things to get an HTPC I built (Lucid & XBMC based) to use HDMI, mainly by updating ALSA. Debian testing doesn’t need the updating though.

I apologise if this is too basic, but the fact that you had sound in VLC makes it appear that HDMI is working, but you are not outputting to it.

Here are a few suggestions from a non-expert:

1) Run "alsamixer" in a terminal, and check that your HDMI is recognised (alsamixer uses various function keys to operate, but has on screen instructions. I am on an XP computer here and can’t check). Possibly choose it as default.

2) Click on the sound icon to get the pulseaudio preferences and change the output to HDMI.

3) VLC and SMPlayer have options to change the sound output. I use SMPlayer, and in the preferences, if I set sound output to ALSA 0,3 (choose from a drop down list), I get the hdmi output. You can feel your way through the VLC menus to find the equivalent. This won’t help with the browser though.

If your problem is deeper than that, I won’t be able to help - but hopefully it is simpler than you think!

That appears to be Gnome alsamixer, which I am not familiar with, but appears to be higher level than just plain alsamixer.

Try:

Code: Select all
sudo apt-get install alsa-utils


Then, after that is done, in a terminal:

Code: Select all
alsamixer


The program looks like this:

F6 changes your sound card.

I hope I am not leading you up the garden path here, but you must have internal speakers as well as the hdmi, so I would expect "Default" plus two other choices to come up.

Well, I am not an expert in ALSA, but I managed to get my stuff working by following this:

http://wiki.xbmc.org/?title=HOW-TO_set_up_HDMI_audio_on_nVidia_GeForce_G210,_GT220,_or_GT240

A lot of which was nvidia specific, but near the end it explains how to configure pulseaudio to see the hdmi out, so that might help you.

Maybe someone else has better suggestions...

Good luck!
