I use Kubuntu 9.04

When I look at sinks, Z Cinema is show as (null). And when I use it as a sink, any sound application freezes until I move it to another sink.

I uninstalled pulse audio and using alsa happily on Z Cinema. Back to the old problem. Now I need to keep changing .asoundconf to change my default device. Pulse audio would be nice.
(Of course I don't mean kde applications)
