Just one of those aha experiences - not sure if anyone is interested but here it is anyway...
On my fc15 x86_64 installation I built and installed pulseaudio-1.1 from the pulseaudio-1.1-3.fc17.src.rpm as found on "http://koji.fedoraproject.org/koji/".
The main reason for doing this is the better emulation of alsa in pulseaudio-1.1 compared to pulseaudio-0.9.2x.
Not only does pulseaudio run perfectly on top of jackd, but it is possible to route alsa only apps like sunvox into qtractor/ardour.
To do this I needed the four scripts listed at the bottom of this e-mail.
I used Qjackctl to run the scripts with the following entries in the options tab of the settings dialogue:
Execute script on Startup: /home//username//.scripts/pulse-jack-pre-start.sh &
Execute script after Startup: /home//username//.scripts/pulse-jack-post-start.sh & a2jmidid -e &
Execute script on Shutdown: /home//username//.scripts/pulse-jack-pre-stop.sh & killall a2jmidid &
Execute script after Shutdown: /home//username//.scripts/pulse-jack-post-stop.sh &
If anyone has a better way to start and stop a2jmidid, I would be interested.

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)
