If you own the Boris Vanian Soundpack for the B737 for in MSFS2020, there is now a free update for in MSFS2024. Below you will be amazed by all the different sounds:

FAQ:

If you have disappearing sounds:
If you have used the workaround for the 2020 version of the sound pack to be used with the 2024 aircraft, please remove it and verify files using PMDG OC3, then install the correct version of the sound.

If you use Chaseplane:
It can sometimes mess up sounds temporarily, especially after using fly-by view. If this happens, go to external (spot) view and then back to interior. This will fix the missing/unbalanced sounds.

Suggested audio settings:
Inside MSFS, sound sliders should be set to 100 for everything except Master volume, voices, other aircraft, music, and interface. Volume limiter and headphones simulation should be disabled. In windows sound settings, spatial sound should be disabled.

How do I get the upgrade?
If you have the MSFS 2020 version of the 737 sound pack, you can add the 2024 version to cart and it will be free upon checkout. Vice versa for the 2024 to 2020 version. This works the same way for the 777 as well.

What about headphone simulation and ABEX/Vickers?
In the 2024 version headphone simulation is done via the headset clickspot, and the hydraulic pump selection is done via the FMC-AIRCRAFT-EQUIPMENT menu.

XBox when?
This is always a long process that takes a while, the only estimate I have is hopefully within a couple months.
