Can't adjust meeting volume

This kept happening to me on multiple laptops with multiple different earbuds, including super cheap ones all the way up to brand new Pixel buds.  Someone on Reddit suggested to change the setting from Headphones to Headset.  Click on the system volume icon in the lower right, and if you see a little "up" arrow by the name of the buds, click on it and see if you can change it to Headset and see if that works for you.

I found this instruction about volume adjustments:  To configure your Zoom audio output settings, you need to open Zoom’s settings. To access the settings, click on your user icon in the top-right corner, then click on “Settings”.

my comment: it was up all the way, next meeting I'll try this to adjust audio.

Hi @kepic welcome to the community! I hope this reply finds you well, as well as @dcurran and @SeattleTwist's replies. Because Zoom pulls in your Audio Devices that are available from the System Level, I'm curious if this maybe something that you maybe need to check within your Windows Settings. There was this Microsoft thread about Headphones not changing Volume; if @SeattleTwist or @dcurran's replies are not helpful; please consider checking out that Microsoft thread on the proposed solution to see if any of the recommended suggestions help. 

I know this post was a while ago, but I've found another solution to this that worked for me. 

Like @kepic , the in-app volume slider wasn't doing anything. I'm on a Windows 11 PC.

What I did was I right-clicked on the speaker icon in my bottom-of-screen toolbar and clicked "open volume mixer". In there you will see specific volume sliders for Zoom, and THOSE will fix the volume problem. 

(I don't know why the two aren't synced up, but try that if you're having this issue and that should fix it as of today's date).
