You are experiencing dropped packets. The 1.0.7 version of freebob 
doesn't report those as xruns. The most recent SVN version does. For 
your pleasure I've released this version such that Fernando can package 
it for optimal user experience ;).

some things to check:
- do you have dynamic cpu speed on? freebob doesn't like that
- what's your host controller make? (lspci -v | grep 1394)
- is your host controller's interrupt shared with another device?
you can use the following tool to check that:
http://subversion.ffado.org/browser/trunk/libffado/support/tools/listirqinfo.py?format=raw
if it is, try unloading the modules that it shares irq with. switch off 
wireless and wired ethernet, plug in your usb devices in another slot, ...

if you post the output of the listirqinfo script and of lspci -v | grep 
1394 I might get a clue. dmesg | grep 1394 can also help (after running 
jack for a while)

Greets,

Pieter

M-Audio Mobilepre USB and JACK/Ardour/Rosegarden

Is anyone using one an M-Audio Mobilepre USB with JACK, Ardour, and 
Rosegarden? I've noticed it is listed on the ALSA project's soundcard 
listing.  I just want to see if anyone is using it before I buy one.

I'm looking for 2 inputs (line/mic) and midi in/out. The Tascam US-122L 
seems to fit the bill too. I'm using a Thinkpad with CentOS5 ATM. I use 
JACK/Ardour2/Rosegarden on my desktop in the studio. I'm wanting to be 
able to use my laptop for some work at home.

TIA

Hi, 
Thanks for the answer but I already have that in limits.conf

Did you log out and back in after installing jack and/or adding the
lines to limits.conf? What does "ulimit -a" give you?

Re: permissions problem with edirol fa-66

Hi,

It might be related to similar problem I had with the latest Jack and
an Edirol FA-101 and this is what I did following Fernando's advice:

I created the file /etc/security/console.perms.d/51-default.perms
containing this:

<firewire1>=/dev/dv1394-0
<firewire2>=/dev/raw1394

<console> 0600 <firewire1> 0600 root
<console> 0600 <firewire2> 0600 root

Then reboot.

That solved the problem for me. I hope it helps.

Hector

Problem with jack

Hi,

I recently did a fresh install of Fedora 8 from a Unity Project re-spin.  It's installed on an AMD Athlon X2
with 2GB RAM, but I installed the 32-bit (i386) OS.  I'm using an Echo Layla24 PCI card, which I have set up in
modules.conf as sound-card-0 (I disabled the onboard HDA Intel sound chip in the BIOS).   I then installed
the planet ccrma kernel (kernel-rt-2.6.24.3-1.rt1.2.fc8.ccrma.i686) and my favorite sound applications.

In jack (Qjackctl), I have it set to use RT, 128 frames/period, 48000 sample rate, 2 periods/buffer, 8
input/8 output channels, etc.  I started up echomixer (to control hardware levels on Layla 24), qjackctl,
and zynaddsubfx to try out a little midi and audio using an external keyboard controller connected to
Layla's MIDI IN port.  

When jack starts, the message window says "Enhanced 3DNow! detected" and "Using SSE2", but the status
window (main qjackctl panel) has the "RT" indicator light alternately flashing on, then off, then on,
then off, ...   I don't remember seeing this behavior before.  Then after some time, jack just shuts down.  At
one point, while playing a synth patch from zynaddsubfx and multiple keys/fast passage, it just locked up
with a very annoying constant tone (incoming! take cover!).

Just for reference, I tried installing Fedora 7 (stock as well as ccrma-rt) on this hardware setup and had so
many problems I decided to give F8 a try.  In F7, eth0 would mysteriously go down (IRQ released), the
soundcard and alsa would randomly disconnect (IRQ again?), etc.  

I'll try and get some more output from dmesg, /proc/asound/, etc that might be of more assistance, but I
wondered if anyone had seen the "RT" indicator light going on and off like this in qjackctl?

Thanks,
Len

Yes, Len, I see that in the current and recent versions. (I think it's 
supposed to look like a flashing "ON AIR" indicator.) IMO, the more 
recent qjackctl program is much more annoying to use, as the RT 
indicator flashes rather than staying solid, and you can no longer close 
qjackctl while leaving the jack server running. But I haven't got around 
to commenting about it.

I hope you find the source of your disconnection problem though! I'm 
using an RME HDSP 9652, and it's flawless. With F8 and the latest 
packages, I get no dropouts even at the lowest latency settings.

Thanks,
David

Does all this happen in the standard Fedora kernel?

Sounds like missing interrupts or something like that. Does it happen
with all programs? Always?
