Speaking of funny things Jack is doing, I get this strange message when I
startup Jack:

apparent rate = 48000
creating alsa driver ... hw:0|hw:0|64|2|48000|0|0|hwmon|swmeter|-|32bit
control device hw:0
configuring for 48000Hz, period = 64 frames, buffer = 2 periods

20:20:16.110 Server configuration saved to "/home/andyj/.jackdrc".
20:20:16.110 Statistics reset.
20:20:16.113 Client activated.
20:20:16.115 Audio connection change.
20:20:16.116 Audio connection graph change.

Then everything works fine.  I have 26 inputs and 26 outputs on my HDSP9652.
It seems to happen 26 times =)
This only happened after I built Jack (on gentoo) with the jacktmpfs flag
on.
Could that be contributing to the occasional xrun?

I'm posting here because I don't want to join yet another mailing list/forum
=)
