Hi,

What's your soundcard? I think being able to open
a sound device multiple
times is dependent on if the hardware supports that.
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.

I can run jack and
xmms (without the jack plugin) concurrently on my sb512.

Now that I think about it, no, I'm not sure about that. I've usually
reserved JACK use for Ardour, so I might not have ever tried running a
non-JACK app with the server open.
Greetings:
I'm having an interesting problem with JACK (0.81.1). When running it
I can't start non-JACK apps, e.g., after starting JACK (with Rui's neat
qjackctl) I'm unable to open Snd until I stop JACK. Is this expected
behavior ? I hope not...
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. :(
