Weird... Could be a bug in VLC or the libac3 ... or the driver for those
speakers. You should report it to the appropriate maintainers.

Note that the internal sound chip should work with recent kernels. If
not, it may just be a matter of a small adjustement. Can you send me a
tarball of /proc/device-tree on your machine ?

There is some basic 3D acceleration available yes (it doesn't do HW TCL
etc...yet but it's good enough to play QuakeIII for example :)

To get it, you should look at the freedesktop wiki for details I
suppose. Basically, you need:

 - Up to date kernel DRM (current -git should do)
 - Up to date X.org (from CVS)
 - Up to date libdrm (from DRM CVS)
 - Up to date Mesa tree to build the DRI drivers

I hope that once X.org 7 (and 6.9) are final, things will be more
readily available, which hopefully should happen fairly soon, or at
least -RC snapshots should be available.
