With all this talk about laptops, I was wondering if there's anything I can do to make mine usable. My main audio computer has been on the fritz recently, so I'd like to be able to work with my laptop while I'm troubleshooting. The problem is that the best latency I can get is 2x1024 frames, which comes out to 42.7 ms at 48000 Hz. This is clearly not usable for live processing work. The laptop is a couple years old, and has a 1GHz AMD Duron processor and 256MB of RAM. I've got a 2.6.20 kernel patched with ingo's RT patch, set to full preemption, and with all power management disabled. I'm using Debian's most recent PAM package to give my regular user realtime privileges and the following in my limits.conf: @audio - rtprio 99 @audio - memlock 100000 @audio - nice -10 Jackd doesn't complain about not being able to get realtime, so I think that's working. Also, when I use chrt to look at the priorities of the jackd threads, there are 2 of them running SCHED_FIFO with priorities of 20 and 10. /proc/interrupts tells me that VIA686A (my onboard chipset) is the only thing on IRQ10, and chrt tells me that IRQ10 is running SCHED_FIFO at priority 50, as are all the other IRQ threads. Boosting the priority to 60 doesn't seem to make a difference. Is there anything more I can do? Thanks, spencer
