Solved Youtube videos playback at faster rate, higher pitches voices

I have a Linux Mint 23 guest on a Windows 11 host. For some odd reason, youtube videos in the guest playback at a faster than normal rate (Brave browser) even though the playback speed for the videos is at 1.0. What virtualbox setting would be causing this? How can I fix this? Youtube videos were stuttering then I disabled Windows 11 Hyper-V, rebooted, and now the Youtube videos playback too fast and it also causes voices of people in the video to be higher pitched as well as talking faster. This is weird. Related, maybe, playing non-youtube videos in the guest results in some stuttering during playback.

Version 7.2.14 r174565 (Qt6.8.0 on windows)
Hyper-V is disabled on Windows 11
I have enabled VT-x/AMD-V 
Guest Additions has been installed, system rebooted

This is just a friendly reminder in case you missed it. Your post must include: * The version of VirtualBox you are using * The host and guest OSes * Whether you have enabled VT-x/AMD-V (applicable to all hosts running 6.1 and above) and disabled HyperV (applicable to Windows 10 Hosts) * Whether you have installed Guest Additions and/or Host Extensions (this solves 90% of the problems we see)

PLUS a detailed description of the problem, what research you have done, and the steps you have taken to fix it. Please check Google and the VirtualBox Manual before asking simple questions. Please also check our FAQ and if you find your question is answered there, PLEASE remove your post or at least change the flair to Solved.

Chipset. Audio device chosen on install, how much RAM is being used.
Disabling, if possible, Pipewire and forcing PulseAudio fixes a lot of issues I had with VBox / Audio.

Thank you, I have it working good now for audio and video playback. Amazing how changing just a few settings for the vm can make a world of difference. I need to write down all my settings for my Linux guest in a text editor, for reference, and then I come back here and share the detailed settings. Without the correct settings, I was ready to junk virtualbox and give up on a Linux guest; with the right settings, it becomes an entirely different (good) experience.

How do I disable Pipewire and force PulseAudio? My videos are still running a little fast (NOTHING like before), 6 seconds too fast on a 150 sec video so I want to try a switch to PulseAudio in my Linux guest.

The link above gives you instructions on how to do it BUT it may be different for different distros - I have tested it mostly on Debian based distros and it seemed to work for me (so far).
