    Ubuntu 10.04 sound problems

    I have upgraded my Dell Dimension, dual boot from Breezy Badger to 10.04.
    My mic no long works and the audio is terrible. When I boot back to XP the sound is all fine.
    I gather the problem must be with the drivers installed for the sound card with 10.04 but am unsure what to do to correct this.
    Any help appreciated.

    Try this:
    Using a Terminal="Applications->Accessories->Terminal"
    Code:
    sudo pulseaudio --kill
    rm -r ~/.pulse ~/.asound* 
    sudo rm /etc/asound.conf
    Logout/in.

    Next tweak mixer levels.
    Alsamixer
    Using a Terminal="Applications->Accessories->Terminal"
    Code:
     alsamixer
    Press <F6> to select the correct soundcard.
    Press <F3> to show playback levels. <F4> selects capture levels [or use <Tab>]
    Use the left/right arrow keys to select and up/down arrow keys to change levels. <M> to mute/unmute.

    Gnome-alsamixer
    Using Alt+F2 run dialog
    Code:
     gnome-alsamixer
    Use 'Edit -> Sound Card Properties' menu to enable elements.
    Soundcard tab to select / adjust levels.

    Re: Ubuntu 10.04 sound problems

    Thanks Lidex but when I enter:

    sudo pulseaudio --kill
    rm -r ~/.pulse ~/.asound*
    sudo rm /etc/asound.conf

    in the termnal I get this :



    cliff@cliff-desktop:~$ sudo pulseaudio --kill
    [sudo] password for cliff:
    E: core-util.c: Home directory /home/cliff not ours.
    E: main.c: Failed to kill daemon: Permission denied
    cliff@cliff-desktop:~$

    Is there a syntax error or did I do something wrong ?

    Just skip the first command and run the last two.
    Haven't I seen you somewhere before?

    When I try to run gnome-alsamixer in the run dialogue I get "could not locate the file."

    Thanks for your continuing help

    Probably doesn't come with the default install:
    Code:
    sudo apt-get install gnome-alsamixer

    Re: Ubuntu 10.04 sound problems

    I am making some progress with your help.
    I installed alsamixer and appear to have adjusted the output levels satisfactorily so I get clear sound out of the speakers. both with mp3 and Cd music.
    But I cannot yet get the mic to work.
    I notice with alsamixer loaded there are two vertical slide bars for mic.
    When I untick the mute on one the mic begins to broadcast through the speakers - so I definitely know it's working !
    Problem is I can't seem to configure things to record, say, through "Sound Recorder" or Skype.
    I note there are two selection boxes underneath the mic sliders "mute" and "rec" - but tried various combinations without success.
    One other thing - and I don't know if it makes a difference - when I invoke "Sound Preferences/Input " the slider identifies the Analog Microphone as "unamplified" and I don't know if that makes a difference or how to change it.

    With alsamixer, press F4 and set CAPTURE and press Z (you must set left audio record as 0 and right audio record as 100)

    Something like that: http://i48.tinypic.com/315bi1y.png

    Hummm
    Great thought except that Capture brings up sliders for something called "3D Control"
    Not 'mic'
    I'm not sure how to include a screen capture of this in this reply..
    I tried adjusting the 3D Control - but to no avail - and of course I don't really know what the heck I'm doing.. ;o)
    I do appreciate the help I am getting and am becoming more3 confident we'll get this resolved.

    In gnome-alsamixer, Use 'Edit -> Sound Card Properties' menu to enable elements. Try ticking/unticking elements there. Then use pulseaudio volume control (pavucontrol), the 'input devices' tab, to select the mic.
