Hello @bishop Welcome to the forum!
The issue you are having with the WAV files sounds similar to a problem someone else was having recently on here.
I would recommend checking out this post and trying some of the suggestions.
I’m not sure about the issue with the CSV. It would be helpful if you post the code you were trying to run so others can get a look at it and better diagnose the problems you are having.
Remember to start and end all block of code with 3 tick marks - ```
Best of luck!
