Where do I find this wrapper script? I use ubuntu studio hardy on amd64, and am just starting to play with jack, ardour, hydrogen, and the constellation of stuff out there. so far it seems that i have to kill pulseaudio from the command line (ps thru grep to find then kill via pid); start ardour, jack, et al, and when done I seem to have to LOG OUT and BACK IN to get pulse audio back. Yech. Not to mention the whole log on/off processes take way too long to begin with. This script sounds like a headache saver; how do I get it and use it?
Thanks in advance,
In Response To:
I had a problem with ardour/jack/pulseaudio in Ubuntu Hardy and I was
told to take it to the mailing list. I cc'd parties that may be
interested. Please ignore this mail if you are not.
The related bugs in Launchpad are:
The problem is that ardour as installed by "aptitude install ardour"
doesn't work. Recording is possible but playback doesn't work.
I was able to resolve the issue by manually starting jack with "jackd -d
My only concern is a working ardour after installing. For me it is
extremely annoying to have manually fiddling with jackd.
I also do not care about latency or similar stuff.
I also imagine a new user (read composer/musician) to linux who
immediately returns to windows after playback in ardour doesn't work.
Also it is not possible to use for example mplayer and ardour at the
I was told that configuration of jack is a non-trivial thing to do
because a professional user normally has a second sound card and jack
has to be configured to use that (professional) equipment.
My opinion is that it should be possible to provide a _default_
configuration where jackd connects to pulseaudio (this is what
module-jack-source is for, right?).
Let me repeat my two concerns:
1. Ardour in Ubuntu Hardy doesn't work out of the box
2. It is not possible to use mplayer and ardour at the same time
I believe it is possible manually fix this up but I have still the
opinion that it should be possible to provide a simple default
So please convince me that I'm wrong (and it isn't possible to have a
working ardour on a notebook) or tell me how this can be resolved.
You put so much hard work into ardour/jack/pulseaudio that it should not
fail because of a small configuration mistake.
