    No sound, Dell Studio 1747, HDMI

    [UPDATE: solved, see post #7 below for solution. In fact, contrary to the title of this thread, it doesn't seem to have anything to do with HDMI]

    Hello,
    I'm having very little luck in getting sounds/audio to work on my new computer. Any help would be greatly appreciated! It's a new Dell Studio 1747 with an ATI Mobility Radeon HD 4650 graphics card and what Dell calls "High Definition Audio 2.0". As far as I understand the sound is also somehow from AMD/ATI. The problem is that it is making no sound whatsoever. No system sounds, no WAV or OGG playback, etc. The computer seems to think that everything is working fine, i.e. audio files will play (e.g. in Totem, or by typing aplay -D plughw:1,3 tada.wav) - but everything stays silent. I assume that it has something to do with having the right settings for HDMI audio.

    Here's some more information in the hope that it helps to identify the problem:

    Code:
    lspci | grep -i audio

    Any help greatly appreciated!!
    Thanks!



    PS: Another thing I've noticed is that every minute or so I hear a tiny popping sound (similar to when you turn plug speakers into a soundsystem, but MUCH less audible) and the fans turn themselves on for about 5 seconds. This may be entirely unrelated, though. I can't tell whether that sound is coming from the speakers as it is really very quiet.

    Oh, hot on the heels of my first post, an update. I've managed to get just a little sound out of the machine!

    I added options snd-hda-intel model=dell-m6 to /etc/modprobe.d/alsa-base.conf.
    (tip from here http://www.rschulz.eu/2009/11/dell-s...h-kubuntu.html)

    As a result the system-ready sound is playing perfectly! I.e. the little bongo-drum-roll when the login screen appears.

    But as soon as I login - again: no sound

    Any ideas?

    Im using the same chipset as you, and from what I can see it looks like your sound output in gnome is using the ATI output, which is for the sound on the HDMI output of your system. If you go to sound preferences in gnome and select internal audio, does that work?

    Thanks for the suggestion. Could you tell me how I would do that?

    Please see the attached screenshot. I don't seem to have another option than the HDMI device. Or am I missing something?

    Thanks again.

    Hmm, I think something might be missing, not sure what though. Have u tried just a general update through apt? I've attached a screenshot of what appears in my output

    First of all, in the sound preferences/hardware tab I had to select "Internal Audio" under "choose a device to configure" and set it to "Analog Stereo Duplex"... only then would it let me to select it in the output tab. Before, as posted above, it wouldn't appear in that list.

    Then, and more importantly, I had to modify the alsa-base.conf file. The relevant part is to add these lines to the end of the /etc/modprobe.d/alsa-base.conf file:
    Code:
    # Keep snd-pcsp from being loaded as first soundcard
    options snd-pcsp index=-2
    alias snd-card-0 snd-hda-intel
    alias sound-slot-0 snd-hda-intel
    options snd-hda-intel model=dell-m6
    options snd-hda-intel enable_msi=1
    The full reference for this is: https://answers.launchpad.net/ubuntu/+question/75137

    Thanks again! Sound is working great.

    Thanks a lot.
    Carried out the same steps. Works fine. Thanks again. Mine is a Dell Studio 1558 with HDMI.

    Re: No sound, Dell Studio 1747, HDMI

    Just a quick update after having installed Lucid Lynx:
    Most things worked out of the box, only the sound would not play through headphones. I.e. plugging in headphones would mute the speakers but no sound would come through the headphones.

    That was easily solved by adding the following line to /etc/modprobe.d/alsa-base.conf
    Code:
    options snd-hda-intel model=dell-m6
    That's all.

    (Dell Studio 1747 with Ubuntu 10.4 Lucid Lynx 64-bit)
