it happens with me too. the problem is in the
module sound-oss in the pwlib
the module that deals with oss (the freebsd sound system...)
tries to resample the stream and than loops... consuming all the cpu.
the folowing patch solves the problem for me
name this file to patch-oss and put it in /usr/ports/devel/pwlib/files
and than... cd /usr/ports/devel/pwlib
make clean deinstall package
