My Xiaomi Mi 6 call volume has gradually decreased to very low. Call volume during other apps like whatsapp and IMO is acceptable but direct phone calls are almost impossible to hear. Current ROM version is 9.5.8 stable.

Any fixes/leads will be highly appreciated.

Unfortunately same for me too. I'm on the newest MIUI 10 beta (xiaomi.eu), but the problem started in July.

I have the solution. And its ****ing simple.

Clean the earpiece with needle and toothbrush.
I also had the same problem, i tried every app, i also tried changing values in mixer_path xml. Nothing worked.
Until i came by a post in the official xiaomi forum.

I was floored. It worked.
The thing is, mi6 earpiece has a a grill with very fine holes. Dust easily blocks the grill.

Poke the grill with needle, clean the grill's perimiter with the needle, then brush it. You can even use a damp cloth to attract the dust. Voila, sound is loud again.

I know your pain, and now the pain is gone. Lol..

I managed to fix this on two of my MI6 - it is all about dirt that is stuck between metal receiver hole and tight plastic mesh under it (some water splash proofing i guess) You have to take off glass cover from the back, unscrew motherboard and gently remove earpiece. Then with needle remove that tight plastic mesh and you will find lots of dirt under it. Use that needle again to clean it all. Try blowing some air to be sure its clean. Then assembly all back together and test the receiver - you will get extremely great sound that finally makes real stereo experience in youtube and other sources. And of course you will hear everything while phone call. Magic!

I used compressed air today from the front into the mesh. Shouldn't that be enough to blew that dirt away from the mesh?

Isn't there any software that boosts earpiece? Don't really wanna open the phone if not absolutely necessary...
