Just got my Kwikstik and ran through the demos. I tried the 2 second audio record demo and plugged my headphones in to hear the playback. The noise level - which sounds like an oscillator running at a few kHz - is very high to the point that it's hard to hear the recorded sound over the noise.
I wondered about noise coupling in from the PC USB, which shouldn't be a problem, so I tried the demo again with an isolated USB power supply. Same noise levels.
Is this normal? I didn't expect CD quality but even the demo should record reasonable audio quality. It sounds to me like there may be a hardware issue coupling noise into the analog section of this board in which case I need to send it back.
Has anybody else noticed this?
Please tell me if this is posted in the wrong place. I assumed there would be a Kwikstik category but didn't find one.
