Hi Simon,

Thanks for the info - awesome stuff.

Just a few questions. 1. There's no reason why these scripts cannot run 
with 0.9.2 right?

2. what version of jackd are you using - from the repos? or have you 
compiled your own with DBUS support? (jackdbus only just hit f16 
recently and you are using f15)

As for your question about a2jmidid I just pkill it also.

Another script I use in f16 that I put in my path is this: (the $1 
parameter is either start or stop. pre|post in yr examples). I'm a 
developer so most people won't be using a lot of these services anyway, 
but you can tailor it for your needs:

fedora16:~ $ cat ~/bin/audio_services
#!/bin/bash
beesu systemctl $1 nfs-idmap.service nfs-lock.service ksm.service 
ksmtuned.service abrtd.service cups.socket cups.service 
sm-client.service  sendmail.service ntpd.service mysqld.service 
httpd.service libvirtd.service crond.service sshd.service smb.service
if [ $1 == "stop" ]
    then beesu modprobe -r ath9k
    else beesu modprobe ath9k;
fi

Cross posting to Fedora-music also as I think this is of keen interest 
there (apologies)

Brendan
