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?
This is what irritates me the most: If I change the settings (e.g.
setting frames/period to 512) I get exactly the same constant behaviour:
14:31:09.787 XRUN callback (1).
14:31:22.482 XRUN callback (2).
14:31:26.495 XRUN callback (3).
14:31:29.025 XRUN callback (4).
14:31:30.185 XRUN callback (5).
The driver "firewire" does not have a -S option. ffado svn:
