DISCLAIMER: All of this is "to the best of my knowledge" which is somewhat
limited, but I'm sure someone will step up to correct me if I'm wrong! =)
I had a problem similar to this very recently with my SB AWE32 PnP. It
turns out that the driver was having problems allocating DMA buffers because
low address memory had become so fragmented. Since I have a decent amount of
RAM (128M), I recompiled the kernel to load up the DMA buffers at load time
and maintain them.
This can be done 2 ways:
1. If you compiled sound support as a module, you need to pass the
parameter dmabuf=1 to the module when it loads. Read the man page on
update-modules for more information about how to get that into
/etc/conf.modules.
2. If you compiled sound support directly into the kernel, there is
an option in the sound menu to preserve DMA buffers. mark it Y and
recompile.
CAVEAT 1: This may not really be the problem you are looking at. If not, I
can't think of anything to try. =(
BONUS: Even if it is not, if you have a reasonable amount of memory, it
isn't going to hurt anything by doing this.
CAVEAT 2: If you are using the kernel autoloader to load sound support, that
may not be the best idea. I would either stic k it in /etc/modules, or
compile support in as necessary.
Good Luck
