Setup:
Dell M90 (intel-hda audio)
Kernel 2.6.24 RT PREMPT SMP from gentoo pro-audio feed
quadro 1500fx with nvidia driver (i'd really like to keep this driver, unless compiz works now with the nv driver)
I've tried multiple combinations of: irqpoll noacpi noapic pci=biosirq, some combinations help to reduce latency, but not enough to be useable
I have GNX4 Guitar interface that works as a usb device, its almost useable with the same settings the intel-hda card skips with.
I have an Opteron with sb-live that no no latency problems, and the GNX4 works great with it.
What suggestions for Frames/Period, Sample Rate, Periods/Buffer would people reccomend to make this useable. I really just want to be able to mix and output audio in realtime on my laptop with its intel-hda card, full duples with the GNX4 on it would be an added bonus.
If anyone is willing to look over the kernel config I can send them It, didn't want to clutter the list with it now.
