FYI...
Regarding the message below...
When I CVSUPed to 5.3-beta5 [FIVE]...
... all my sound output stopped working!
KDE wouldn't make sound
Audacity wouldn't output
XMMS got an error related to output
I performed a port upgrade last night as described in the
article below and now all sound seems to work fine.

Hope this is useful.

Subject: Re: Maestro3 and 5.3-beta5
Since it worked before, it sounds like DMA buffer
allocation issue.
Can you try attached patch? It doesn't fix your
issue but it checks return code correctly and we
can know whether DMA buffer allocation
was successful or not.
If DMA buffer allocation was successful I have
no idea. If you see DMA buffer allocation failure
you probably can workaround the issue like this:
Step 1. Make static kernel with your sound drivers.
Step 2. add vm.old_contigmalloc=1 in
/etc/sysctl.conf
If you needed step2, maestro3 driver needs
rewriting for its memory management code.
Cheers,
