I have had to do a complete reformat and reinstall.
I have got the XP tweaks from TASCAM.
It says my sound card should have it's own IRQ. but it is sharing IRQ19 with "SiS 900-Based PCI Fast Ethernet Adapter".
Does anyone know if this is a problem I should try and resolve. I have read some stuff from M-Audio about IRQs but it gets well complicated for this part time hobbyist.
