New page
If you experience problems while wanting to upgrade or remove the SOUND4 driver, follow this procedure.



You can have the driver version with <code>cat /proc/sound4exp/version</code>



First, to avoid reload at reboot:



<code>sudo rm /lib/modules/$(uname -r)/updates/dkms/sound4exp1.ko</code>



Then, try to remove current from dkms (exemple for version 2.1).



<code>sudo dkms remove -m sound4exp1 -v $(cat /proc/sound4exp/version) --all</code>



For more recent ubuntu, it might be this command instead:



<code>sudo dkms remove sound4exp1/$(cat /proc/sound4exp/version)</code>



If this freeze on unloading driver, you have to reboot the PC and retry.



For all versions before 2.8, the package removal script try to disconnect the driver, which freeze with most recent enough kernels. So



<code>nano /var/lib/dpkg/info/sound4exp1.prerm</code>



and comment line 



<code>echo "1" > /proc/sound4exp/disconnect</code>



Then you can update the driver:



<code>sudo apt-get update && sudo apt-get install sound4exp1</code>



If asked to <code>dpkg-reconfigure -a</code>, do it and retry.

 If you are stuck with the message "Disconnecting sound4exp1 driver..." or "Unloading sound4exp1 driver...", you should try the followings:
-# Remove the driver, so it won't be loaded at next boot : <code>sudo rm /lib/modules/$(uname -r)/updates/dkms/sound4exp1.ko</code>  If the kernel has also been updated, the next reboot will be on a different kernel, so you will have to redo this and reboot, or you may delete all installed versions with <code>sudo rm /lib/modules/*/updates/dkms/sound4exp1.ko</code>
