Re: [Line6linux-devel] UX2 - sysinfo

[Petter S. S. <pet...@gm...>]

I have installed the newest version in the branch/ux2 now, and I am happy
to say; It worked! I got no error when I started up with the device plugged
in, and I was able to record my guitar. First with just audacity, but also
with Jack, Ardour and Rakarrack. Great work guys :-D Happy to see that the
community makes it work without line6!! One problem tough.. My monitor
works just on the right side, and the sund is NOT very good. But I "fixed"
this with turning monitor all the way down in alsamixer, and then use jack
to route back after recording/rakarrack. So for me this doesnt matter. I
also have two playback in jack, instead of four that I had before, but I
really dont know what the last two was.. I'm just happy everything works
:-) Now I can consider moving my "musicproduction" to linux, finally.
