There is a petition tunning on
http://www.petitiononline.com/NVAPU/petition.html, requestion continued APU/SoundForce chipset support. It's a Good Initiative, so do sign up, folks!
Currently, the petition doesn't mention Linux support for existing and possible future APU's.
I'd like to see the following added:
-----
Further, the community strongly advise nVidia to fully support the APU,
in its present and future forms, on the Linux platform.
-----
On nforcershq, there's been a sticky about wanting SoundForce support for a while:
Tell NVIDIA you want SoundStorm Support in Linux!!
