Windows 7, VIA HD Audiodeck

[Belldl]

I'm having a few strange problems, I think related to the "VIA HD Audiodeck" software which came with my onboard sound card, but not sure. I'm trying to record from an ION turntable, Windows 7 64 bit, Audacity beta latest version. Everything worked fine a month ago when I was using Vista 64, same hardware, and Audacity 1.2x. (its same hardware, clean install of W7 not upgrade)

At first I couldn't record at all, but I went through and reminded Control Panel->Sound to record using USB, 2 channel, adjusted level, and reminded Audacity Preferences->2 channel.

At first I was getting a weird echo effect in the recording - everything sounded kind of metallic and with a slight reverb which I'm sure is not on the actual album. Very noticeable, as the first record I attempted to encode was Peggy Lee's "Fever" (every fingersnap played twice!).

I played with some settings, I wish I remember what now, and it cleared up in the recorded .wav - but now, when I record the play-through has the reverb effect - like everything is playing twice about .25 second apart. The recorded wav is fine though. It shouldn't be feedback, because the playthrough is coming through headphones so the sound can't be making its way back to the tone arm? It's not a terrible problem, but still annoying that I can't listen to an album as its encoding.

Could any of this be related to the "VIA HD Audio Deck" control panel, which seems to have controls for managing all audio except USB?
