wifi calling in Pixel 4a 5g, I can't hear

Having the same issue with my Pixel 5. There are times when I'm on a call using wifi calling and all of a sudden I can't hear the other person. I turn my wifi off and I'm able to hear again just fine and continue the call. 

I've come across where I have wifi turned on, but not connected to any wifi signal and still have the problem.  I was on the road and making a call, I couldn't hear who I called but they could hear me. I turned my wifi off on the phone and I could hear the other person fine.

Pixel 5a on Tmobile network.  Occasionally, phone calls have no incoming audio.  By the comments in this thread, it seems like I need to troubleshoot by working through all combinations of:

∆  Experimenting with network types (i.e., 4g, LTE, 5g) 

∆  Experimenting with reception types (i.e., cellular only, wifi only, cellular and wifi both enabled)

∆  Experimenting with call origin (did I initiate the call, or was it an incoming call)

∆  Experimenting with using the speakerphone function versus non-speakerphone.

∆. type of phone on the other end (is it some weird iPhone thing).

This is ridiculous.   How is it that a cellphone can't do the most basic function...phone audio.  It's in the name:   cellPHONE.   C'mon people.

Don't hold your breath for a fix.  This has been broken for over a year now, and no progress is evident.

does disabling wifi-calling work for anyone (to bypass this problem)?  because i've disabled wifi-calling and i still get the issue.  Seems super unreasonable for google/tmobile to expect us to simply disable wifi all day long because we might get a call at some point...

@ocmyhome if I disable wifi calling completely I do not have the problem

@jonpaterson I want to say I attempted this and still ran into the issue, but this was awhile ago.  I'll go ahead and disable this feature and see how it goes.

I'm having the same issue with or without wifi calling on pixel 5. Has anyone found a solution? Or identified if it is a hardware or software issue? 

Same issue here (hah). This happens during a call. Sometimes the caller cannot hear me but I can hear them, and vice versa. It has happened with old sim, new sim, and WiFi on/off. Finally trying to figure this out.

Same issue on my wife's T-Mobile issued 4a 5G. Wifi calling works fine on my OnePlus 7 Pro NA (non T-Mobile variant).

I bought a pixel 4a 5g straight from google. It's fully stock. When I'm on WiFi calling, I almost always (not always though) can't hear the other side on the call and have to switch to cellular. The other side of the call reports hearing me without an issue.

 

My phone is fully updated with google updates.

I'm having the same issues on Pixel 5. The other side of the call says they can hear me fine, but I can't hear them. The only fix is to disconnect from wifi. 

Did anyone find a more permanent fix?
