Buzz noise with Maudio 1010 at 96000 Hz


Is my first time posting, so I don’t know if this is the right place to ask about it. I have got an Maudio 1010 card which is working fine at 44100 Hz. When I increase this set up in JACK it starts making a buzzing noise. At 96000 Hz the buzz comes up to around -33 in Ardour mixer faders. I know is something related to the sound card because I am using other inputs (Addictive drums, Zynaddsubfx,…) and they don’t do any noise at all. It have to be something related to the distro. I am actually using Ubuntu Studio 9.10 Karmic. Before with Hardy 8.04 it was working fine. With all the next releases is making the noise. Does anybody know about this? should I contact Ubuntu Studio rather than Ardour? Any help would be much appreciated. Many thanks.
By the way. Great job Paul.
