I've released a new version of the DLL. Major change is to convert the audio streaming to use DirectShow & DirectSound. Give it a try. If you use Vista, see the note in the "filters" directory.

I'm thinking of building one of these with the Si4734 and Si4707 chips, but I have no hardware design experience. I've written a support message to these guys, and I am wanting to build a portable player that incorporates both of these chips using 4 wire or I2C and a complete tuner/capture program.
I think these chips can do it, but again, without hardware experience, it's hard to say. Anyone interested?

I have written my own front-end, and with the use of Wickerswammie's USBRadio.dll and a VB6 sample code 'SilabTest' I managed to implement the radio in my VB.net project. I find the reception excellent, not quite as good a quality as listening to the CD player or MP3 player, but radios never are.
The RDS is a little bit slow at displaying the station you are tuned too, but the radio text is jumbled. Apart from that the radio works very well, and the signal strength data that can be obtained from the radio is always about 75%. For for the price, it is a must for all car computers. Even with 50Gb of MP3's, it's always nice to listen to the radio now and again.
I'm only speaking from experience in England, it might not be as good in America and other countries, but over here it works fine 
Hello I have been working with my silabs usb radio for a little bit and while it does get some reception, it doesn't get as good of reception as what my old radio used to. Before I got power to it, it was hardly getting any radio at all. The thing is, mine doesn't look like those in all of the pictures I have seen in the forums here. When I took mine out of the casing, the antenna was fastened to the PCB on a metal square piece and that was it. I assume maybe it was connected to the ground plane somehow in the middle, but I don't know. When I soldered the coax to it, I put the core of the wire in the big hole left by the antenna and took the foil/shield wires to the outer casing of the usb. Did I do this correctly? I would assume it should sound better than it does currently. Any help would be appreciated. Thanks

I'm probably gonna get pounced for this, but FreeICE works with the Silabs and is one of the simple-est front-Ends to install.

funny that, but with my other soundcard, a cheape $9 thing, i used to get sound on the real from the fm.
when i updated my system and got a mb with built in soundcard, i lost it.
seems the drivers for my original card automatically duplicated stereo sound sources onto the rear channels, and the new one does not.
Whats most annoying is that media player when playing mp3 _does_ duplicate the front channels on the rear!
I have not been able to get this working in over a year of trying different drivers.
soudcard that did work for me was the cmi chipset, the 6 channel one, but it was the chipset which could stlll do line in while doing 6 channel out, think it was the lx, or not the later, cant remember
