Debian

Hello,

I've installed a dual boot : windows and debian on a new multimedia pc.

On Windows, I can get the sound from the tv passed by the HDMI cable. Windows works fine as usual.

However, I connected my laptop up (running squeeze) to my Samsung TV and though the picture comes up fine the sound only plays via the laptop.

My cat /proc/asound/cards tells us:

Code:

 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xfcef8000 irq 42

                      HDA NVidia at 0xfebfc000 irq 17

                      USB Device 0x46d:0x821 at usb-0000:00:1d.7-4, high speed

Code:

Since using Windows (which I'd prefer not to!) both picture and sound works fine, so I assume it is some Debian related issue.

Any suggestions where I should look? Settings? Missing packages?

Thank you in advance

I had a similar issue a while back when Wheezy was first introduced and again when I started using MATE almost exclusively. I found that ALSA was my problem and by installing PulseAudio (with its associated requirements for different DEs) the problem went away because I could select HDMI and know it would work as it should.

PulseAudio was not the solution to your problem. You probably dont know how to use alsa

Got it ...

I had to make "1,9" changed to "1.9"
It works now, and I reconfigured alsa to start hdmi as card 0.

Probably Alsa was just useless and Pulse did the job first time. I posted a thread somewhere, maybe not in LQ, and got no answers at all. I remembered Ubuntu moved to Pulse, and got totally bagged for it to, so I gave Pulse ago and it worked where Alsa, no matter what I did with settings, wouldn't.

Glad you got Alsa working though with some fiddling. Don't forget to mark the thread as solved.

I had to create a file called '.asoundrc' under my home directory to get sound over HDMI.

Code:

pcm.!default {
      type hw
      card 1
      device 7
 }

EDIT: Using kernel 3.2.0 with an nVidia GTS450

or my self with ATI card and HDMI I had problems I couldn't see the HDMI in the hardware sound when tryin opensuse I tried several thing and ended up breaking it so I installed mint and still couldn't find any HDMI settings at all in the hardware\sound so I intall the ATI fglrx drivers rebooted and looked and found the HDMI there then just used that.
Now I am not sure if this will work for you but you could try if all else fails.

I had a similar problem on Wheezy, with an ATI card, for whatever reason it showed my HDMI sound card as unclaimed, IIRC I read that they'd blocked that functionality because of some issues with the ATI open source drivers.

I had the exact same problem except the other way around (could only get sound with HDMI) (see thread) and here's how I fixed it:

I placed the following code in '~/.asoundrc'

Code:

defaults.ctl.card 1
defaults.pcm.card 1
defaults.timer.card 1

What is your processor? With a standard stable install I didn't have the module for HDMI audio on an Intel i series. Jessie worked perfectly. Of course an kernel update would have worked as well, but this was a new install so I just couldnt be bothered.

Installing pavucontrol did the trick for me. Try the following:

* install with "sudo apt-get install pavucontrol"
* start a video in browser and redirect video to TV
* invoke pavucontrol using "alt+F2 pavucontrol"
* click Playback tab
* set "Playback on" to Built-in Audio Digital Stereo (HDMI)

HTH,

Eric
