I posted that message to the JACK list. Anybody has the same problem? sbdy at the JACK list said that it disappeared with kernel 2.6.10... I have not tried this (I'll wait for the package) but I find it strange. -------- Missatge original -------- Assumpte: strange-difficult to explain BUG Data: Sun, 19 Dec 2004 17:14:24 +0100 De: Respon a: A: jackit-devel(a)lists.sourceforge.net reproduce it under XMMS with the jack plugin.... When running jackd and using audio applications, after some time (for example 5minutes but not always the same time), I start listening a strange noise added to the music, then it stops, it comes again later but after a lot of time and like this until the end of the world. you can download it under the following link: http://www.upcnet.es/~mvr9/proves/jack_bug.ogg (during the silence between tracks you cannot listen it, even if it started already in the previous track) When I hear the noise, if I switch to the ALSA plugin, I can hear the music OK; but if I switch again to jack it the noise continues. The noise stops spontaneously after some time (1minute?) independently of the fact that I listen to music or I don't play anything. When the noise stops Jack displays in the message window: "**** alsa_pcm: xrun of at least 0.058 msecs". This is normal????? I am running the last version of jackd under Debian testing: 0.99.0-2 with parameters (through qjackctl): /usr/bin/jackd -R -p60 -t5000 -dalsa -dhw:0 -r44100 -p512 -n2 -S -i1 -o2 (short latency: 23.2ms) with an audigy card, with a kernel 2.6.8 + realtime module my fstab is the following one: maybe this explains why I am the only one (i didn't hear of anyone) complaining about this bug? sh-2.05b$ more /etc/fstab # /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 /dev/sda8 none swap sw 0 0 /dev/sda5 / ext3 defaults,errors=remount-ro 0 1 /dev/sda6 /home ext3 defaults 0 2 /dev/sda2 /winsegur vfat rw,user,exec,codepage=850,umask=000 0 0 /dev/sda1 /winxp vfat rw,user,exec,codepage=850,umask=000 0 0 /dev/hda /media/cdrom0 auto ro,user,noauto 0 0 /dev/hdc /media/cdrom1 auto ro,user,noauto 0 0 /dev/fd0 /media/floppy0 auto rw,user,noauto 0 0 /dev/sdb1 /marc vfat rw,user,exec,noauto,codepage=850,umask=0 00 0 0 /dev/sdb2 /home/marc ext3 noauto,user,exec 0 0 /dev/sdc1 /media/usb0 vfat rw,user,exec,noauto,codepage=850,umask=0 00 0 0 music...
