I'm hoping I'll be able to find someone else with a similar setup that
has overcome their problems to get realtime operation, at least in one
direction, with no xruns. <br><br>Setup:<br>Dell M90 (intel-hda audio)<br>
Kernel 2.6.24 RT PREMPT SMP from gentoo pro-audio feed<br>quadro 1500fx with nvidia driver (i'd really like to keep this driver, unless compiz works now with the nv driver)<br><br>I've
tried multiple combinations of: irqpoll noacpi noapic pci=biosirq, some
combinations help to reduce latency, but not enough to be useable<br>
<br>I have GNX4 Guitar interface that works as a usb device, its almost
useable with the same settings the intel-hda card skips with.<br>I have an Opteron with sb-live that no no latency problems, and the GNX4 works great with it.<br>
<br>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.<br>
<br>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.<br><br> cat /proc/interrupts <br> CPU0 CPU1 <br> 0: 20489426 0 XT-PIC-XT timer<br>
