How to assign wineasio to a different soundcard?

[lavadisco]

I installed wineasio, opened my pro audio program (Reaper via WINE) for the first time, and it worked with my laptop's onboard soundcard with no other tweaking! No winecfg or JACK Control or anything. Great! However...

I want wineasio to recognize my Edirol UA-25 USB audio interface instead. How do I do that?

Then you have to set your UA-25 (great device BTW ;)) as the default in gnome-sound-properties (Sound Properties).

I did that, it didn't work.

Sorry, I must've been low on cafeine ;)
You need to set up JACK for your UA-25 (I can provide some settings if you want to) and hook up wineasio through JACK. At least, that's what I recall the last time I used Guitar Rig.

Thanks, I'd be very grateful if you'd do that. Been reading up on Jack, but there is so much out there that it is a bit confusing.

Do you find it odd that Reaper and wineasio worked with my onboard soundcard with no tweaking of Jack in the first place? How did that happen?

Reaper opens using the wdm audio device by default, so it should work, but not likely at the low latencies provided by asio.
Install qjackctl, and click everything, taking notes, and google for anything that is new or strange to you. Lots of hits/info out there!
Cheers.

Check the attachment for the settings I'm using in Qjackctl for the UA-25. The only thing that might differ from your setup is the Interface address. If you click on the > you should have the option to select the UA-25.

Thanks! It worked. I did have errors with Jack at first, but once I added my login to the audio group with realtime permissions, everything was cool.

One issue - I am not getting nearly as low of latency with this setup that I used to get on my Windows XP system. Will I get better performance if I switch to the realtime kernel? If I can get to 6ms, I'll be happy.

The numbers are not important, and won't match equally on a different OS, so if you can't hear/feel latency, any numeric label it has is meaningless. :) But larger multi-track or heavily layered productions may need the benefits of the realtime setup. Cheers

Thanks guys. To record electric guitars well, I feel that I need 6ms latency or better. Sounds weird/late to me otherwise.
