If you're talking about the RCA Lyra Wireless xmit/rec units, I have this 
but am not sure of the version.  I don't have the software CD.  XP 
recognized the USB transmitter right away and gave me it's own mixer panel.

Anyway, I connected it to my PC and transmitted audio from the sound card 
into a another room where the receiver was connected to a TV's audio in, so 
I know it works great.  Electronically, it's about the same as running a 
direct cable from the PC's audio out into the audio in of another device.

This reminds me of a project I did once where the CoCo in one room 
transmitted a cassette audio packet into the CoCo in the living room 
telling the receiving CoCo when to display a caller-id screen, complete 
with the person's custom name, in large white letters on a black 
background.  My entertainment center allowed me to have this in a PiP box 
quickly and could see who's calling while I was watching TV.
In fact, it was the dreaded WebTV Plus unit combined with all my other 
goodies.  Talk about nice.

The transmitting CoCo had an external modem that had caller ID capability 
and my software took that small amount of data that was sent in and made a 
CSAVEM packet out of it, and the receiving CoCo was always in CLOADM mode 
within a BASIC program that displayed the data.  I also had a PC device 
call TeleSound connected to the CoCo's RS-232 Pack that could mix audio 
into the phone connection and also feed the phone audio into a sampling 
device/recorder.  This is where I had the ability to not only answer 
certain calls automatically, but to play custom messages.  I had to hack 
the TeleSound device so it would answer/hangup the call from the CoCo.  It 
had something to do with the DTR signal or another typically unused RS-232 
Pack signal.  Anyway, it was too many wires and trouble to keep this good 
thing going for too long.

The reason I used two CoCo's is because I didn't want my main CoCo being 
tied up like this doing all the work and having to be behind the TV, 
etc.  Company always asked me how they could get that on their TV.  I could 
easily program it to recognize a telemarketer's number, then answer and 
hangup very quickly, killing the bugging rings.  :)   At this time I was 
living out of state in a small town, so I eventually tracked all of the 
payphones, as well.  I could tell in 1 second where one of my crazy buddies 
was calling from.

I had built my personal phone assistant.

What I had in mind with the Lyra units is not to transmit music but 
audio-encoded data.  There is no 1200/2400hz limit as with the CoCo's 
cassette file format, so I'm sure some advanced techniques could be used to 
transmit a lot of things over the air (or through wire).
