Hi, Can you run through the HOWTO here: http://www.davehayes.org/2007/04/27/howto-reaper-on-ubuntu-linux-with-wineasio and let me know how you get on - any problems following it, etc. If you've still got problems ... then I'm stumped! Good luck. -- Peter amadeus wrote: > Peter, thanks so much for your reply > Yes I can send from Linux sound apps to Jack in stereo, but I can't in wineasio, its two signals combined into one,the L - R are both one signal, but there is only one channel in them, I think its the right ONLY being heard in both sides. So you see I have no stereo because of this. Sorry I made a mistake about the wineasio version its not 1.74 there is no 1.74 but it is 0.74 oops. > > Thanks again, hope to get this fixed ;) > > > > > >
