Hi Tobias,

believe me or not: Thats *exactly* the same thing, i have programmed today :-(
Unbelievable!

My patch does have 1 more line:

diff -rub DVB-23apr03.orig/driver/av7110/av7110.c

@Holger: I really do have a original Siemens DVB-C 1.6 with mounted analogue 
module. Why is my subsystem_vendor_id that different??

Anyway, i have tested your patch, Tobias (as in the CVS), it works perfectly 
(like mine :-(!

But your (and my) patch does not help with *my* problem :-(

I am using the AC3overDVB patch with VDR (means: i use the "Digital-Out" of 
the DVB-C card). I am still not able to control the volume of this output :-(

Does anybody out there know, how to control the volume of the "Digital-Out"?
Or is this totally impossible?

The MSP34xx chip does have some "Dolby" registers. What are the function of 
these registers??
