    Unhappy sound doesn't work

    Hi, all

    I'm turning to you after few days of fighting with the system. I have no more ideas and whatever I do, it doesn't work.

    I started playing with sound a couple of days ago because my mic didn't work. During this time I have updated, upgraded, disabled and enabled, uninstalled and installed again. And now the sound doesn't work at all. Although sound controls show that both speakers and mic work. Still, I can't hear a thing. Could you please help me fix it?

    I'm running Karmic on my HP dv6.

    Oh, and please, I'm not that smart. Please tell me what to write in the command line, not what I should do

    Re: sound doesn't work

    Open a terminal window and enter this:
    Code:
    speaker-test -t wav -c 2 -D plughw:0,0
    This will play back test sounds on the left and right speaker. You can stop the test by pressing Ctrl-C.

    If the test proceeds without an error message but you don't hear anything, check your mixer settings. Run alsamixer or gnome-alsamixer and turn all the sliders up until you hear something.

    If the test program aborts with an error message, copy and paste it here.

    Did you turn up all the volume sliders in the mixer? If you use gnome-alsamixer, some sliders may be hidden by default. You can make them appear by changing the preferences.

    I have done all that. All the volumes are at maximum, everything unmuted (well, apart from the pc beep but i don't think that this matters here). I did that in sound options, pavucontrol and alsamixer. Still no sound.

    To me, it looks as if there was something muting the speakers but I can't reach it. The system starts with sounds muted, I don't know why. But even when I set all the volumes at max, and one would think it will work, it doesn't.

    Re: sound doesn't work

    There are two sound cards in your computer. The first one (card 0) has two output devices, analog and digital.

    "plughw:0,0" means that the test is run on the first device of card 0. In your case that is "STAC92xx Analog".

    Is that the correct card/device? For example, if you use the digital output jack, "plughw:0,1" would be correct. If you use the HDMI output, "plughw:1,0" would be correct.

    Are you using headphones? Did you activate the headphone jack in alsamixer?

    Re: sound doesn't work

    That's the thing that confused me a bit. I'm using the built-in speakers, so I think the analog output is relevant here. I assumed the HDMI stands for the socket in the laptop but I've never used it.

    I tried connecting the headphones and trying if the sound would work that way, but it didn't.

    The alsamixergui shows: Master, Speaker, PCM, Front, Capture and Mux at max levels and Mic Jack Mode, IEC958, IEC958 Default PCM and IEC958 Playback Source at 0 and I can't move those controls.

    Re: sound doesn't work

    What did you install/uninstall when your microphone didn't work? Maybe it would help to reinstall all the base ALSA packages to get the system back to its original state.

    Re: sound doesn't work

    Ooohh... I didn't do much. I added pavucontrol and earcandy (that doesn't work). Apart from that I uninstalled PulseAudio at some point but as nothing worked then, I reinstalled it again.

    Basically, I think most of the things are the same... If there is something else, I really don't know what. And, well, the sound is not working any more.

    Re: sound doesn't work

    Well, there must be something that triggered the change from "mic not working" to "sound not working".

    Did you install Ubuntu from a live CD? What if you boot the live CD again and check if sound works there? The live CD is the easiest way to test these things on a "default" setup.
