[linux-audio-user] Can you record with OSS & Esssolo1?

Another, hopefully not too obscure, question... I have a Fedore Core 1 system that I'd like to record radio programs with. I found a great little program, RadioCap (http://www.scheinwelt.at/~norbertf/radiocap_homepage/), that will do just that. It listens to /dev/dsp for its input. FC1 uses OSS as default, and for the soundcard in this particular machine it was working fine using the ESSSOLO1 driver. When I plug the radio into my mic or line-in ports and unmute the channels, I can hear the radio through the PC's speakers. But no input level shows on RadioCap. I did a few tests with XMMS, etc., and it certainly seems to be using /dev/dsp for sound. Is this a sound card problem? If I can hear the input, shouldn't it be able to record it? Any suggestions would be appreciated. Thanks, Jay
