[pvrusb2] no audio with PAL and tda9887

[Mike Isely]

Michael:

Which msp3400.ko are you using?

The msp3400 that is part of kernels from 2.6.15 onward has a changed 
command set.  The current driver snapshot does NOT adapt to this and thus 
there will be no sound.  I just now made this realization (as I was 
debugging a similar problem here).
