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. /Robert > I can run jack and > xmms (without the jack plugin) concurrently on my sb512. > > Taybin > > -----Original Message----- > From: Dave Phillips <dlphilp@xxxxxxxxxx> > Sent: Sep 18, 2003 7:54 AM > To: linux-audio-user@xxxxxxxxxxxxxxxxxx > Subject: Re: [linux-audio-user] JACK splat > > Robert Jonsson wrote: > > Thursday 18 September 2003 14:19 skrev Dave Phillips: > > > Greetings: > > > > > > I'm having an interesting problem with JACK (0.81.1).
