Reverting to ALSA
If, for some reason, you want to go back to ALSA, here is the procedure: (I tested this myself on my test system)
The preceding command opens your blacklist file in the text editor. Delete all the lines from "blacklist snd-seq" down to the end of the file (make sure the last line in the file refers to a snd module and was not added by another program).Code:sudo soundoff sudo dpkg -r oss-linux sudo dpkg-reconfigure linux-sound-base sudo apt-get -y install libesd-alsa0 alsa-oss alsa-base libsdl1.2debian-alsa gksudo gedit /etc/modprobe.d/blacklist
Restart the PC.
Now, re-install ALSA kernel modules with this script: http://ubuntuforums.org/showthread.php?t=820959
Go to System -> Preferences -> Sounds and select Autodetect or ALSA
Any applications that you configured for OSS should be changed back to ALSA, although they should work with the alsa-oss wrapper.
Optionally, you can setup and configure PulseAudio. I have no experience with this, but I have seen guides for it (use search). If you do, remember to install the Pulse-compatible libflashsupport package:
Code:sudo apt-get install libflashsupport
