Latency perf: I measured a latency of 11ms (with no
xrun except a
handful of on start-up) after:
1) increasing the PCI bus latency of the ieee1394 OHCI controller to
243 (see "Tuning the hardware" at
http://www.soundfabrik.net/wb/#linux), and 2) recompiling a vanilla
2.6.11 kernel with the PREEMPT flag turned on. No more, no less...
That's really a *great* improvement compared to the talk of Daniel
Wagner at LAC 2005 where he told that the latency still is at 50msecs.
Great to see that firewire audio support improves!
Best regards
