[linux-audio-user] USB MIDI and Audio

I'm pleased to say that the Oxygen 8 now works with my RedHat-based laptop, after installing the latest stuff from Planet CCRMA. The only problem is that now my USB Audio interface fails. ALSA appears to be starting OK: [root@gimel jzitt]# /etc/rc.d/init.d/alsasound start Starting sound driver snd-usb-audio [ OK ] Starting sound driver snd-usb-audio [ OK ] Starting sequencer driver snd-seq-midi [ OK ] Restoring sound driver settings [ OK ] [root@gimel jzitt]# But jack hangs: [root@gimel jzitt]# jackstart -R -d alsa -d hw -r 44100 jackd 0.41.1 Copyright 2001-2002 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 loading driver .. creating alsa driver ... hw|1024|2|44100|swmon starting engine cannot lock down memory for RT thread (Cannot allocate memory) **** alsa_pcm: xrun of at least 0.074 msecs (and there it sits until I do a ^C) I'm also seeing an error from lsusb for the Audio interface: Bus 001 Device 012: ID 0582:0006 Roland Corp.
