Muse cannot connect to Jack - Jam - 05-17-2011

Hi,

got a strange problem with Muse and Jack. When I try to start Muse1.1 it gives me the error-message:
"MusE failed to find a Jack audio server.
MusE will continue without audio support (-a switch)!
If this was not intended check that Jack was started. If Jack was started check that it was started as the same user as MusE."

But: Jack is started, and both, Jack and MusE are started normal, so yes, both as the same user.

If I start MusE from a terminal there comes the message:

"~$ muse
Denormal protection enabled.
no message buffer overruns
no message buffer overruns
unknown option character l
cannot connect to jack server
cannot create jack client"

Everything else I tested (abmdec, ardour, zynaddsubfx) run well with jack (at least until the moment the system crashed because of the muse-problem).

I use UbuntuStudio 11.04 and the lowlatency kernel (by Alessio Bogani). MusE1.1 is part of the Ubuntu-Studio-repositorie.

Anybody got an idea?

This is a workaround, not a solution.
Switching to jack1 will allow muse to work, but this shouldn't be necessary. Will muse 2.0 work with jack2?

Hm, can't confirm this. Muse 1.1. and Muse 2 beta working here with jackdmp 1.9.5 on Suse 11.3.
Maybe a broken Ubuntu Package?

Getting a bit old but thought i'd chime in.

MusE 2 should already work with jack2, if it does not please give us some more information.

Hi,

Jam Wrote:cannot connect to jack server

The most likely reason is that MusE is built with some other jack version, not the one that is currently running on your system.
You could check with 'ldd <muse binary>' and see what jack it is linked with.
For me it's:
libjack.so.0 => /usr/lib/libjack.so.0 (0x007a5000)

Another possibility is that you are starting muse as the wrong user (as root probably), jack by default does only work for the user the jack daemon is started with.
