I normally wouldn't reply but this is way off. If there is prior art
then the patent can be thrown out. This is what PubPat is doing and
what was attempted with the Microsoft FAT patent (and succeeded in
Germany).

If Microsoft took out a patent on something that was implemented
previously in ALSA code but they did not steal the code from ALSA they
are not required to GPL anything. GPL is a license based on copyright.
As long as they don't copy the code they're not breaking any laws and,
unless someone can prove that they copied the code, they ar enot
required to reveal it.
