Audio has never worked well with the us-122 on my box. When it does work, the sound is clippy/choppy. This happens even before jack makes any complaints. I've tried every conceivable jack setting. Here's my latest configuration, along with a log that ends zobmified. Should I just give up and sell the damn us-122? (my PCI audio card works fine...but is noisy; which is why I invested in the us-122) 22:08:26.920 /usr/bin/jackd -R -p256 -t10000 -dalsa -r44100 -p1024 -n2 -D -Chw:1 -Phw:1,0 22:08:26.924 JACK was started with PID=5642 (0x160a). jackd 0.100.0 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. loading driver .. apparent rate = 44100 creating alsa driver ... hw:1,0|hw:1|1024|2|44100|0|0|nomon|swmeter|-| 32bit control device hw:1 configuring for 44100Hz, period = 1024 frames, buffer = 2 periods Note: audio device hw:1 doesn't support a 32bit sample format so JACK will try a 24bit format instead nperiods = 2 for capture Note: audio device hw:1,0 doesn't support a 32bit sample format so JACK will try a 24bit format instead nperiods = 2 for playback 22:08:28.985 Server configuration saved to "/home/dextron/.jackdrc". 22:08:28.986 Statistics reset. 22:08:28.988 Client activated. 22:08:28.988 Audio connection change. 22:08:28.989 Audio connection graph change. 22:08:39.970 Audio connection graph change. 22:08:39.996 Audio connection change. 22:08:39.998 Audio connection graph change. 22:08:40.184 MIDI connection graph change. 22:08:40.201 MIDI connection change. 22:10:31.593 Audio connection graph change. 22:10:31.632 MIDI connection graph change. 22:10:31.750 Audio connection change. 22:10:31.752 MIDI connection change. jackd watchdog: timeout - killing jackd zombified - calling shutdown handler 22:10:37.271 Shutdown notification. 22:10:37.273 Client deactivated. 22:10:37.275 JACK was stopped successfully. cannot send request type 7 to server cannot read result for request type 7 from server (Broken pipe) cannot send request type 7 to server cannot read result for request type 7 from server (Broken pipe) Other interesting factors: I'm running 64 bit Ubuntu Dapper, dual core processor, NVIDIA nForce 4 chipset based K8N Neo4 motherboard
