greetings list,
When I run PD under linux using an edirol UA25 and Jack, I get some pretty nasty noises every time i switch windows.  When I do the same thing in Windows (sans jack), I don't get this problem.  I've tried running pd with alsa but that doesn't work.  I do have a 16 bit pci soundcard installed.  Would removing that help?  Or how would I edit my alsa configuration to remove the PCI card and just use USB? the alsa configurator program doesn't make any mention of the USB device.
