A question re: alsa-lib
I have tried to upgrade my version of the alsa-lib today but synaptic
complains with the following message
alsa-lib:
Depends: alsa-driver (>=1.0.10) but 1.0.9b-1.rhfc4.ccrma is to be
installed
Depends: config(alsa-lib) (= 1.0.10-3.1.rhfc4.ccrma)
Is there an easy fix to this problem ?
