Sound problems

Asked by Gibby

Hi I am a newbie - so be gentle

I am running 8.04 and I noticed today that I have very very low sound output. I tried listening to stuff online but only hear the faintest sound.

I went to System >> Preferences >> Sounds and clicked on the "Log in" PLAY and I hear that loud and clear :-)

BUT

When I play a CD I have to turn my speakers up to half volume just to hear the music, it's the same with a DVD :-(

Anyone know why I can't hear anything else ?

Thanks, Gibby

Hey gibby

we are gentle in here so dont worry

Audio trouble with Ubuntu 8.04 some common checks

-- Please check your sound devices volumes are to a high level double click on the top right loudspeaker icon you will see a mixer
-- Please make common test from menu System->Preferences->Audio
-- If you have two audio cards - please disable the on board audio card using BIOS setting
-- Please be sure your pc are starting with the generic kernel press ESC at boot when you see the GRUB row then select the "kernel.... - generic" row
-- Please be sure all needed kernel modules are installed to make this check and install them:
  So open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install linux-ubuntu-modules-$(uname -r)

give your user password when requested, you don't see nothing when you type it, then press enter.

Then reboot your pc.

-- Be sure your user is member of audio group
Then open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo adduser $(who am i | cut -d" " -f 1) audio
sudo chmod 660 /dev/snd/*

give your user password when requested, you don't see nothing when you type it, then press enter.

-- Please try to watch what audio cards are detected on your system please type:
asoundconf list

if more than one sound cards is detected by your system to set the default soundcard

asoundconf set-default-card PARAMETER

change PARAMETER with the name of a one detected sound card

-- Please try to delete making a backup copy of this conf files
mv .asoundrc .asoundrc_old
mv .asoundrc.asoundconf .asoundrc.asoundconf.old
sudo mv /etc/asound.conf /etc/asound.conf.old

Please take a look at this http://ubuntuforums.org/showthread.php?t=205449

-- Please try to discover if there are any process they are keeping the /dev/dsp locked
ps -edalf | grep -i dsp

and you have probably already done this, but just in case you haven't ...

go to System/Preferences/Sound

and in Sound Events, Music and Movies and Audio Conferencing change "Autodetect" to ALSA - Advanced Linux Sound Architecture.

Bhavani Shankar.
