dear moto tech; suggested inital test steps for root cause analysis:
1) reboot phone
2) goto sound settings and see if changing the levels causes output or not via speaker
3) if yes, quarantine the phone while powered up for let's say 30 minutes
5) record data and analyse
6) fix our phones

I'm having the same problem here as well. Tried all of the suggested fixes and I still get no audio most of the time through the speaker. I've never heard of a phone that has such widespread problems out of the box.

I have a Moto G Play 4th Gen Standard Version (no Amazon ad version).
Mine too has lost all speaker sound for no apparent reason.
-Turning it off and back on.
-Turning it off, removing battery, draining the remaining power, then reinstalling the battery and starting the phone.
-Clearing all cached data
-Performing complete Factory Data Reset.
None of these actions restored sound to the speaker.
The phone has hardly been used and has never been activated with a phone carrier. I use it as wifi only. I believe the problem started as a result of an automatic update. Please provide a solution.

Same problem on my phone bought directly from Lenovo.
Problems started last week with voice calls going through but no sound on either end. But sound came back after a reboot.
Then I started having problems playing videos. Any video actually: YouTube sends back an error, and local videos on my SD card won't play on any app.
Then yesterday, no sound whatsoever, from speakers or headphones.
Safe mode reboot doesn't change anything.
Backed everything up.
Wiped the phone cache: I started getting sound from headphones only, but this went down again after a few minutes.
Performed a factory reset. Even before installing anything, it's clear there is no sound.
I find it strange too that the boot sequence no longer goes through the "hello moto" animation, straight from blue screen to unlock.
Since I bought my unit at release here in Europe, warranty's just expired, and I'm not too happy with the situation, especially after reading through this thread.
I'll try getting in touch with customer service but I don't have a lot of hope.
