I received the Apple Airpod Pro's for Christmas. They work flawlessly with my 2 laptops and ipad. I'm still a Note 9 lover but need the audio fixed. The audio level you would expect works great on all devices except the Note 9. I have a Verizon Note 9 with the current updates. The Airpods have the latest firmware.
I've enabled Developer options to disable absolute volume as other andriod users have suggested but did not see any improvement.
And yes, it have the call, media and system volumes at their maximums.
Are there any other settings that can be adjust to fix the low volume?
