Most probably not. It looks like that the ALSA people accept some
patches, replying "OK", but in the end the never make it into the CVS.
Happened to me sometimes, could be the case here.

This one, contributed by someone here on the list (cant remember right
now). Its related to PCM streams being paused ans resumed. While pausing
the DMA context seems to get lost, so this extra call reestablishes the
DMA context.

There where some segfault problems, because at some time the ac97 struct
could be null and the macro being used. Using a variable that is
initialized at startup when the ac97 struct is not null for sure, solved
the problem.

All current patches on my website should be considered obsolete... while
there could be some things that where silently omitted by the ALSA
team :(

Until i don't get my hands on a Desktop machine, it impossible for me to
do any further testings. Unfortunately i will keep being very busy at
least one more month. After that, there are chances to take over a
Desktop x86 with a free PCI slot and some free time.
