Does anyone have any suggestions for a suitable webcam/setup to record audio and video of playing the piano from above?

I recently tried a Logitech c920 webcam on a windows laptop and while the video quality was good, the sound of my digital piano was muffled and distorted.

There are a lot of suggestions on the web to improve the sound of this webcam, but none have proven to give a decent sound quality.

I am beginning to think that this may not be the right application for this webcam.

Has anyone else been successful in creating a good audio/video stream of their playing?

If so, what equipment have you used to do this successfully.

Any tips are welcome. Thanks
