Acrobat Pro, Windows:

1) The "Record Audio" Comment option doesn't work well: a really loud background noise is always present, and I have to massively strain my voice to beat it. (If I forget to strain it, the recording has a fade-in effect where the recorded sound is inaudible at first, but then gets better a few seconds in.)
This is not a hardware issue - tried different laptops & different microphones (internal and external). Searching the forum, I found that this issue has existed for more than a decade (https://community.adobe.com/t5/acrobat-discussions/is-there-a-way-to-fix-the-static-noise-problem-in-record-audio-comments-in-acrobat/m-p/14383077#M448422), please fix it.

2) Also, whenever a recording is made, the "Sound Attachment Properties" settings window pops up - regardless of the fact that I had already previously checked off the "Make Properties Default" box.

TIA!
