just an update, and a reminder to tascam us-122 users: make sure acpi is turned off. i've struggled (off and on) for about half a year to get stable low-latency performance out of this device (connected to a dell inspiron 1150). it's been quite frustrating at times - semi-stable high latency performance, with maddeningly random alsa timeouts - terribly unstable low latency performance, with jack losing connection to alsa around 2 minutes after starting. with acpi and cpuspeed turned off, rtirq and permissions set, snd-usb-usx2y module loaded with nrpacks=1 parameter set, and using the hwX,2 hwdep experimental alsa interface, i've been running at 256x2 (11.6 msec) with zero overruns and no audio glitches for about 10 hours now, and am confident enough in the system to take it on stage. acpi was the real dealbreaker. based on google searches it's the same story on windows. thanks much for all the archived advice i used to get to this point. i don't recommend the interface, by the way. far cry from the m-audio pci stuff i'm accustomed to, where i could install the programs and leave them running for weeks at a time, and everything just worked. and i never would've bought the thing had i done enough research to see it only has RCA outputs. still, getting the thing running stably is a huge step for me - you've no idea how excited i was to get home from work and see qjackctl's start button still grayed out. back to learning ardour. pd at some point. -- daneasley@xxxxxxxxx dan@xxxxxxxxxxxxxx dan@xxxxxxxxxxxxxxx http://towndowner.com http://burntpossum.com
