Left scroll wheel no longer controls volume

Installing 2021.24.25.1 on my 2015 S 85 now. Will report back if this is the fix for the volume scroll bug as well as the seat profile not changing names on the screen bug.

Sidenote: I drive 150+ miles daily. Car seems a little more efficient after the update but maybe its just because of the cooler weather.
 
I have the same issue on my car. It happened after updating from 2020 to 2021.24.25 over the weekend. I did soft reboots and power off - NO LUCK. Should I take it to my local service center?

Also what happens if you are just out of warranty and something like this happens?
Problem was fixed for me this morning with 2021.24.25.1. Applaud Tessa for the quick response to this software itch.
 
Seems like it is muted if it otherwise works find but does not adjust the volume. What happens when you press the left scroll wheel when no sound is coming out? Does a press of the wheel control the other things it is supposed to control?

Has this happened to anyone else? The left scroll wheel on my MS with MCU1 no longer has any affect on audio volume.

- Same result regardless of the audio source; phone via bluetooth, native streaming apps, or terrestrial radio
- Volume adjustment on the main screen works fine
- Turning the scroll wheel still causes the volume indicator on the IC to pop up and change up or down as it always has; just does not reflect actual volume change! The display can indicate that the volume is muted and the level hasn't changed at all.
- Recently updated to 2021.24.25 but can't remember if this issue presented before the firmware change or not
- Rebooted the MCU and issue still persists.
Yeap..... about a week ago I noticed the volume knob '18 MS 100 becoming less responsive (but it did work) Today... I can scroll the wheel up/down and the volume indicator might pop up but did nothing. I also noticed that the fwd/bk arrows stop controlling channel selection as well.
I'm running 2021.32.22 and I just got a notice for software upgrade.
Leary that the update might make it worse

I dropped my X off this morning here in Baltimore at Tesla of Owings Mills because of this same issue. This afternoon 4:48 pm they sent a approval invoice of $1288.93 & almost a $1000 if that is to fix steering volume control on my steering wheel. They must be out their mind. Tesla looking like the good old boys with this one. SMH. I will be doing the power down and negative ground trick to see if that works when I get it back tomorrow.

Wow. That's insane.
