At the moment, no phonon is running according to htop.  Should it be?

So I did restart it and:
[gene at coyote build]$ getfacl /dev/snd/controlC0
getfacl: Removing leading '/' from absolute path names
# file: dev/snd/controlC0
# owner: root
# group: audio
user::rw-
user:gene:rw-
group::rw-
mask::rw-
other::---

and now the sound is sputtering, at least for the chime of incoming email.

Its miss-linked somehow.  My script calls it, and it works without throwing 
any visible errors, but its <5% of the speed I had on 32 bit F10.

This is a straight from kernel.org kernel. 2.6.33 tarball + patches.

Does that have a mailiing list?

On freenode I assume, #name please.
