Crackling Sound playing games on new Predator G9-593 laptop

Hi, I just purchased a new Predator G9-593 laptop a few weeks ago and everything seems to be working extremely well exceptf for some sound issues. Overall the sound is fine in video and music, but when i run even a mildly demanding game (i.e. Portal 2) I have a very distracting crackle sound. On more recent games (Agents of Mayhem) the sound crackling is even worse. Also, when the laptop is plugged in, the crackling noise increases quite a bit during gameplay. I've tried the basic troubleshoots such as reinstalling the Realtek drivers; running 'troubleshoot sound problems', changing the driver to 'High Definition Audio Device'; and rolling back to an older Realtek driver. Nothing has worked. Smiley Sad

When i run 'Troubleshooter' everything tests fine, but it comes back with the following caution symbol;

I'm not sure if this means anything....can someone please help!!!

Sorry for the delay!

Trying to update bluetooth from link but it as errored out about 3 times now and crashed to a restrart on the last one. Also had a BSOD a couple days ago linked to Qualcomm. Spoke to a Acer Predator help line and reset to factory. re: the driver download - on the fourth try, it finally installed. I'll test and report back.

Bios is as follows.

Sending it off for repair.

Sucks to have this happening on a new machine. Thanks for all your efforts!

In case anyone, like me, is looking for a possible answer.
Option 1 worked for me >> https://www.drivereasy.com/knowledge/laptop-speakers-crackling-on-windows-10-solved/ << setting the output format of speaker properties to 16-bit 48kHz
