What's your soundcard? I think being able to open a sound device multiple times is
dependent on if the hardware supports that. I can run jack and xmms (without the jack
plugin) concurrently on my sb512.

Are you sure you could do it with other versions of Jack? I don't know how Snd works, but it seems probable
that it opens the
sound-device on startup. And if it is occupied by a sound-server, any
sound-server, the app may not start.
I'm pretty sure Snd operates in just that manner, and I understand what
you're telling me. I also tried opening it with jacklaunch but got no
joy. :(

SBLive Value, and of course it just occurs to me that I've run and
recorded from XMMS with Ardour many times, so the problem must lie
elsewheres, i.e., not with JACK, yes ?

Right, SBLive (emu10k based) has a built in 64ch mixer.
I have heard other stories though that mention problems with similar
situations, though the otherway around ;).
E.g, if artsd is started it's impossible to start jackd. I have not researched
the cause.
Thinking about it, it could be that the different apps tries to open the
device with different settings, samplingfrequency etc... I can imagine that
the card does not allow this.

Yeah, I've got several
emu10k based cards where this is no problem either.
Dunno how it works with my envy24 card, as I generally only run one app at the
time towards that card, I guess it only allows one user though.
My work computer which has really lousy ac97 drivers definately locks things
pretty badly.
IIRC it's possible to open devices in non blocking mode, for which this
problem is not as apparent. The application that isn't allowed to use the
card can atleast exit with a reasonable error message.
