i had a quite similar problem with muse, i think, there are different versions of muse-binaries out there either compiled with support for alsa *or* for jack, AFAIK, there is no commandlineoption to start muse for jacksupport (such as: muse --jack ) but to type: #muse --help wont hurt anyway ;-) i use thacs muse.rpm for Mandrake 9.1 and as i run it setuid root without any serious trouble. (muses jacksupport is, in a word: excellent :-) ) if you compile muse from its sources, it should be possible to turn on jacksupport by giving the appropriate flag to configure. good luck Am Mit, 2003-11-12 um 17.40 schrieb clemens kurtenbach: > Hi all, > > when i start muse i get the following error: > > [root@nexus:ck] muse > no locale <muse_en_US>/</usr/share/muse/locale> > JACK: sample rate changed: 48000 > ALSA: set buffer size, req: 384 got: 768 > ALSA lib pcm_hw.c:1055:(snd_pcm_hw_open) open /dev/snd/pcmC0D0c failed: > Device or resource busy > ALSA: open error: Device or resource busy > > ladccad is running and jackd i started with this options: > jackd -d alsa -d hw:0 -p 1024 & > > Im running 2.6.0-test9, have a YMF-744B and with e.g. xmms > i can hear sound 'through' ALSA. > > Any suggestions ? > > greets > clee
