Hey List, Just thought I'd let the list know how my new thinkpad is doing. I was worried when /proc/interrupts showed my HDA card on the same interrupt as one of my USB controllers and the firewire controller, especially when I was getting crazy xruns even at high latencies like 2x1024. Then I found a handy post from mlesswing on the Ardour forums. Turns out that i just added options snd-hda-intel index=0 position_fix=1 to my /etc/modprobe.d/alsa-base file, and low and behold I can get xrun-free performance at 2x64 (2.9ms latency at 44100!!) I haven't seen how running a firewire drive at the same time might effect performance, so we'll see if the IRQs end up being a problem. Overall, about 24 hours after I received it at my door I'm really happy with the Linux performance. I know people have had a lot of trouble with HDA in the past, and I'm not sure how well known this fix is, but hopefully it can help somebody. -spencer
