2023 Tahoe Z71. Audio volume lowers randomly while driving.

Been happening for awhile. Cannot figure out why it randomly lowers by about 50%. Tried everything. Doesn’t matter if navigation is on or off, phone connected or disconnected (both Bluetooth and wired USB.)

Previously had a 2018 that volume adjusted with speed, can’t find that setting in any menu.

Anyone have an idea?

Found a way t9 fix it, but still don’t know what caused it. Drove 4.5 hours yesterday and it happened every 20-30 minutes. Drove back today, 4.5 hours and it didn’t happen once after doing the following to rest boot infotainment system:

1. Your vehicle must be started and in PARK to reset your system.
2. Press and hold the END CALL button on your steering wheel for about 10 seconds.
3. Then, turn your vehicle OFF, open the driver's door and close the driver's door. Wait for your displays to turn off completely.
4. Start your vehicle again
