sound between BETA4 and 5.3-BETA5

[Ben H.]

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.

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.
