Zoom default starting volume

I agree that is very annoying situation when you need to lower down a volume of the meeting every time when you start or switch to. By having volume at 100%, I can hear a lot of distortion so, quality of voice is really poor. When changed to 33% all back to normal.

This is indeed a serious flaw. I have found that adjusting the Zoom Meeting app's volume slider in the "Volume Mixer" in the Windows system tray is the only way to control the app's volume independent of the rest of ONE's apps. This is only a temporary fix as it will reset if the app is closed. Even more so, being moved to another room in a Zoom meeting also resets the volume back to system volume, blasting the user's ears with an unsafe volume level.

I am currently in a Zoom meeting and I have my system volume at 5% in order to have it at a tolerable level.

An IN APP volume setting like other video and audio conferencing services doesn't seem like it would be too difficult to implement.

Is there a way to elevate this issue? I always have to be ready to pounce on the Zoom level in mixer, in order to immediately lower it when the meeting connects. This is potentially harmful when the sound begins at a level hazardous to hearing.

I'm not really sure if your question/problem is related to standard Zoom Workplace client or to Zoom Rooms.

If it's for Zoom Rooms, then you can change the default volume in:
Room Management > Zoom Rooms > Account Settings > Default Speaker Volume

If it's for standard Zoom client, then it's a wrong place to ask this question and it should be in Meetings section.
