sound stopped working in ubuntu 10.10 suddenly

I have a Dell Inspiron 1525, and sound problems have been very common. In Windows XP the OS used to frequently stop detecting the Intel HDA, and I used to get no devices found errors. After installing ubuntu, I did not get it for a couple of years. Until today.

Check whether you're getting sound with windows, if you dual boot. This is why you should dual boot, it gives you idea about hardware and software problems. In my case, to start off, sound was not working in windows too.

So I run the boot-diagnostics. This is by pressing Fn-power instead of power, or choosing diagnostics from the boot options menu by pressing F12.

I notice that the standard thing that used to come up is gone. Weird. Now I get loads of memory checks, with no sound check options. Anyway, after the checks, I restart windows, and sound works!

I download the diagnostics software from the dell website. This is priceless. I run this, and it does detect the sound, as always. It's just not running in Ubuntu.

Turns out it was an ALSA issue. All I needed to do was reinstall the alsa files. Run this, in fact -

sudo add-apt-repository ppa:ricotz/unstable; sudo apt-get update; sudo apt-get --reinstall install alsa-base alsa-utils; killall pulseaudio; rm -r ~/.pulse*

However, this is for maverick, and so please check this website -
https://help.ubuntu.com/community/SoundTroubleshootingProcedure

Sound is back now!

Hi,
If you need to process images in batches, like resize a lot of images, here's a nice way to do it

1. Download David's batch processor. To do this, install 'gimp-plugin-registry' form synaptic.

2. Go to Filters>Batch and run it. Select the photos and the output folder in rename. Then apply the operation you want.

How to install 64 bit flash

#Copy this in a file and run it in terminal

#!/bin/bash

## First we make the working directory
sudo mkdir -p /tmp/pluginstall &> /dev/null

#choose version of ubuntu
#Input code browser
function strinput {
unset refstr
echo -n "$1"
read refstr
}

## Ask if they agree to file bug reports, sort of a reminder
echo
echo "This script is used to setup 64-bit Adobe Flash 10 Square."
echo ""
echo "By downloading the software listed below, I acknowledge that I have read and agreed to the terms of the Flash Player 'Square' License, the Adobe.com Terms of Use and the Adobe Online Privacy Policy."
echo "See http://labs.adobe.com/technologies/eula/flashplayer10.html"
echo ""
echo " Do you agree? yes or no : "


if [ "$installtype" = "" ]
then
echo -n "(please type the whole word in lower case letters)"
strinput
else
refstr=$installtype
fi

if [ "$refstr" = "yes" ]
then
echo "Flash installing."


## First we uninstall and remove all the existing flash packages

# No longer trying to reply nspluginwrapper since Acrobat Reader 9 requires it
#sudo apt-get -y purge nspluginwrapper
sudo apt-get -y purge mozilla-plugin-gnash
sudo apt-get -y purge swfdec-mozilla
sudo apt-get -y purge flashplugin-nonfree
#sudo rm -rfd /usr/lib/nspluginwrapper
sudo rm -f /usr/lib/firefox-addons/plugins/libflashplayer.so
sudo rm -f /usr/lib/mozilla/plugins/libflashplayer.so
sudo rm -f /usr/lib/mozilla/plugins/flashplugin-alternative.so
sudo rm -f /usr/lib/mozilla/plugins/npwrapper*flash*so
rm -f ~/.mozilla/plugins/*flash*so

## What is current version?
export version="2_p3_64bit_linux_111710"
## Then we make a temp folder and download the new plugin
cd /tmp/pluginstall
sudo wget http://download.macromedia.com/pub/labs/flashplayer10/flashplayer10_$version.tar.gz

## Next we extract and place the plugin
sudo tar xvf flashplayer10_$version.tar.gz
sudo mv libflashplayer.so /usr/lib/mozilla/plugins/
sudo ln -s /usr/lib/mozilla/plugins/libflashplayer.so /usr/lib/firefox-addons/plugins/

echo "Please restart Firefox to enable Flash"

elif [ "$refstr" = "no" ]
then
echo "I am sorry but you have to agree. "

else
echo " I am sorry but you have to agree. "
echo
fi
