Hmm... I've used the usb box in windows and I don't recall analog stereo 
sound being a problem.  I cant check now though, because I'm using it 
right now, using my updates to the cxusb driver in linux, to watch 

Anyhow, the bluebird box does in fact have a cx25843 ....   I don't 
think it has a separate audio chip, but I'll have to open it up and look 
again...  As of now, there is no analog support for this device in linux 
at all, although I'd like to eventually add it.  When that times comes, 
I will probably figure out some of the answers to these questions.

The person who posted on AVS forum.... Which FusionHDTV USB box does 
he/she have?  It's possible that it may be one of the DVB-T versions.... 
(not mine, the ATSC version)  Maybe that explains why I dont know about 
this particular IC.   hmmm???
