I seem to be having a problem when I plug in my headphones into my Lumia 810, I cannot control the volume of my phone call (using the call app). My headphones do not have a volume dial. Although the volume rocker indicates it is decreasing in volume, the audible volume does not change. Has anyone else experienced this?
Can you check for updates from settings> accessories> check for updates?
Let us know if this helps.
I tried the solution in the bluetooth post, and found it didn't work.
I have also tried updating the phone, strangely now, I do get volume adjustment. But, it's inverted. 0/10 on headphones = max volume, 10/10 = lowest volume.
