Hello,
I'm quite a bit puzzled and so I'm hoping to find something I haven't
considered yet. I'm using a FireWire Saffire LE Audio Interface,
connected to the following PCI card: NEC Corporation uPD72873
[Firewarden] IEEE1394a OHCI 1.1 Link/2-port PHY Controller (rev 01).
http://subversion.ffado.org/wiki/HostControllers#NEC
Your controller is marked as "problematic" but if it worked before so
there is something going on.
Software information: ffado built from svn, jack 1.9.8, kernel 3.5.3
PREEMT (no realtime patch) or 3.4.9-rt17 (with realtime patch), libraw
2.1.0.
No matter what I configure jack to run with, I get regular xruns every
few seconds whilst doing nothing. The last settings I tried were:
Frames/Period: 4096
Sample Rate: 96000
Periods/Buffer: 3
(Latency: 128ms)
Did you also try lower frames/period settings? And running Jack with the
-S option? And what prio does Jack have? Do the xruns come in burst or
all the time? Which exact FFADO svn checkout are you using?
Best,
Jeremy
