I can't get another IRQ for the sound card. FWIW, the latency test did work with the TerraTec too, there was some "Voodoo" when it didn't work using the nv driver. However, I try to get rid of the NVIDIA card. I will remove it and check if Linux nowadays is able to enable 3D support for the on-board ATI Radeon X1250-based graphics. Regards, Ralf
