Note:- This is having some packages installed from third party repositories so use at your own risk.
- Before you start: Please read the following points to find out if you should use this guide.
- This guide is intended only for Ubuntu 8.04. Although many steps work for the development release (Intrepid), there are kernel issues in the Intrepid release that I will not currently support in this thread.
- If you are running Kubuntu/Xubuntu/Edubuntu 8.04, this guide is not for you (as PulseAudio is not used for these distribution flavours).
- If you cannot get sound working under any circumstances, then you are probably suffering from a kernel or ALSA bug -- this guide is probably not for you.
- If you have a brand-new sound card that is not supported in ALSA, and/or you are using OSS v4 -- this guide is not for you.
- If you notice a lot of stuttering sound on your system, especially since upgrading to the Hardy release, this guide is for you.
- If you can get sound working in some applications but not others, or you find that audio mixing is broken, this guide is for you.
If you wish to have equalized sound system-wide, this guide is for you.
Procedure to follow
For 64bit/amd64 users only
Please see the following thread and install GetLibs.
When you have GetLibs installed, install the necessary libraries as follows
getlibs -p libnss3-1d
getlibs -p libnspr4-0d
getlibs -p libcurl3
getlibs -p libasound2-plugins
After installing getlibs you need to follow from step1
For 32bit/i386 users only
Remove the obsolete nspluginwrapper package:
sudo aptitude remove nspluginwrapper
Remove obsolete packages and configuration files:
sudo aptitude remove libflashsupport
sudo rm ~/.pulse/* ~/.asoundrc* /etc/asound.conf
Step1:- Procedure to follow
Ensure you have the necessary packages installed
sudo aptitude install padevchooser libao-pulse libasound2-plugins libsdl1.2debian-pulseaudio
Add PPA to your sources.list
gksudo gedit /etc/apt/sources.list
Add the following lines to the end,save and exit
# PulseAudio Fixes
deb http://ppa.launchpad.net/psyke83/ubuntu hardy main
deb-src http://ppa.launchpad.net/psyke83/ubuntu hardy main
Update your repository lists, then upgrade your system (answer yes to install packages that cannot be validated)
sudo aptitude update
sudo aptitude upgrade
Set PulseAudio as the default ALSA device and enable the correct driver for libao applications
echo "default_driver=pulse" >~/.libao
Now you need to Go to System/Preferences/Sound. Ensure all the "Sound Playback" entries are set to their default setting of "Autodetect", otherwise you may experience difficulties.
After logging out and back in, everything should work correctly! These packages will install PulseAudio complete with tweaks to reduce stuttering/CPU usage, and Flash 10 (release candidate). Finally, Flash & PulseAudio work correctly without crashes
