Hi again,In fact, that problem is very surprising. My UA-25 refuses to work under DeMuDi testing (I reinstalled it, and it did not work better). However, it worked under DeMuDi stable, but I did not kept it on my disk, because DeMuDi stable is not synchronized with Sarge. So now I use my UA-25 under Ubuntu Linux with the DeMuDi stable kernel and tuned with the ubuntustudio.com website instructions.
It is probably not the best solution, but it works ! Cheers, AD
