Re: [LAU] Horrible number of xruns in Jack (Emu card)

I got the same processor running 64-bit debian sid running jack at 44.1khz, 64 sample buffer on Audiophile 2496 soundcard with no xruns. Are you running realtime kernel with realtime box checked in qjackctl/settings (or with -R option on command line)? (I got 4GB dual-channel RAM and 2 SATA DRIVES...) My kernel: 2.6.23.11-rt14 #1 SMP PREEMPT RT Wed Dec 26 08:47:49 EST 2007 x86_64 GNU/Linux Norv ----- Original Message ---- From: Darren Landrum <darren.landrum(a)sbcglobal.net> To: linux-audio-user(a)lists.linuxaudio.org Sent: Monday, 28 January, 2008 11:42:08 PM Subject: Re: [LAU] Horrible number of xruns in Jack (Emu card) Darren Landrum wrote: I hope someone can help me with this. I have: Athlon64 Dual-Core 6000+ 2GB DDR3 RAM, running dual-channel 3 x SATA hard disks Emu 1212m sound card Ubuntu Studio 7.10 (Gutsy, I think) Trying to run JACK at 44.1khz, at a 128 sample buffer I'm getting on the order of 50-60 xruns a second. Even at a 4096 sample buffer, I was getting one xrun every 2 seconds. I would think this setup should be able to handle a 64 sample buffer without any trouble. The one caveat is I did have to compile the latest stable ALSA from scratch, so that my sound card would work. Could it be related to the still-beta driver for my Emu card? Or maybe I need to recompile ALSA with some options? Thank you for any help. I talked to my programming prof about this, and he thinks the fact that I'm using a 64-bit OS might have a lot to do with it. I'll try installing the 32-bit version of Ubuntu Studio at some point this week and see if that changes anything (I keep all of my data on a separate partition, so it's not a huge operation for me). -- Darren _______________________________________________ Linux-audio-user mailing list Linux-audio-user(a)lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user Make the switch to the world's best email.
