Hi to all Dreambox knowitall's

On another forum of OpenPLi we are thinking about more audio options in image software.
So I got a few hardware questions, to find out if their is or can be hardware that is capable of those requested audio options.
Like upsampling audio to 96KHz 24bit, 32bands graphic equalizer for each channel. (so 2.0 = 2x32bands, 5.1 = 5x32bands, from 20 till 150Hz off, and 1x from 20 - 150Hz for lfe).

So my questions is:
-What kind of chipset is handling the audio processing on the DM8000 by default. Is it the Broadcom BCM7400 chip?
-If the DM8000 doesn't have requested hardware for audio processing, then i'm willing to ask hardware vendors if they want to create sort of 24bit/96KHz (THX qualified) soundcard to connect in the socket that the extra snap-in DVB tuners use. But what kind of socket is it on the DM8000 mainboard, where the snap-in DVB tuners are connected to, is it PCI-express?

I hope i can get some feedback about this topic, because it would really be awesome if we got some stunning audiophyle settings/options on our Dreambox(in my case DM8000). Or It would be a miracle if their will be a state of the art studio quality audio card to connect in a place where a snapin tuner is connected to.

Volume control is mainly for the analog output. it's not nessesary on Digital outputs, since we prefer a standard digital output amplitude(for the digital audio receiver)
