Thanks for that useful information, but can you tell me exactly how to
perform the update? I tried 'yum update *alsa*' as I have the Elrepo
repository installed, but it came up with 'No Packages marked for
Update'. Do I need to completely remove all the currently installed ALSA
packages and then do 'yum install kmod-alsa? Any advice gratefully
received, thanks.
