No audio on phone calls

Bug Reports
1

REPRODUCIBILITY: ~25%
OS VERSION: 5.0.0.62
HARDWARE: Xperia XA2 Dual SIM
UI LANGUAGE: English
REGRESSION: Issue present since at least 3.4

DESCRIPTION:

Sometimes phone calls have no audio in either direction. When this is happening, it happens for every subsequent call until the device is rebooted. All other audio functions work as expected.

PRECONDITIONS:

Phone call.

STEPS TO REPRODUCE:

  1. Make or receive a phone call. If it works, turn off the phone, turn it on and try again.

EXPECTED RESULT:

To be able to hear the other person and for them to hear me.

ACTUAL RESULT:

No audio in either direction, no slight hum or hiss from the speaker, nothing.

MODIFICATIONS:

None.

ADDITIONAL INFORMATION:

This has been happening since 2020. I understand it’s considered an old phone at this stage, but it seems pretty poor form that this issue has persisted over multiple major software updates since the XA2 was first supported. Is it a case of being unable to fix it, or unwilling and hoping that users will eventually drop the XA2 and the problem will be “solved” that way?

It’s a long-known bug, see [3.4.0.22] XA2 phone calls no audio - #140 by amaretzek for more information

Just to chime in that I have never experienced this, on an XA2 Dual-SIM.

You can try to make heavy use of AppSupport (+ Browser).
As I said, this happened less on phones with small load (at my place).

Indeed, I’ve also posted in that thread over the years. But I re-raised it against the latest major OS release because that thread reference is two major releases old at this stage.

Hmmm, I’m not a heavy user of the phone in terms of Android apps or the browser, so if that’s the cause then it must be really sensitive! But even so, it shouldn’t be the case that the most fundamental feature of a phone can be torpedoed without warning simply by using other functions.

I am still experiencing this issue on 5.0.0.67 using a Sony Xperia 10 V.

I recently experienced something like this.

Xperia X 10II, SFOS 5.0.068

I called tech support. They had several numbers. One, a normal cell phone number, then 1 or 2 service numbers (starting with 010 or 020 in Finland).

No problem with the cell phone.

Calling one of the other numbers, I heard an automated announcement, then when - presumably - the technician picked up, I heard nothing.
This part is reproducible!

He called me back and everything was fine. I asked him, he said he didn’t hear me either before.

This makes me think that there might be a switch in technology after the automated announcement? That makes SFOS fail?

I also notice that I never hear a ring tone anymore. When calling someone, the “toot toot” before they answer. Once they answer everything is fine.

Oh, I had a similar experience in summer (same phone and probably the same OS-Version). I tried to call my bank to block my credit card in the night. And after the automatic anouncement the call ended suddenly. I thougt it is on the side of my bank, because its a small bank. But perhaps it could be a SFOS-problem related to yours.

that no “toot toot” sound part disappearing is typically happening when the person you are calling is using volte while you do not. If the person you call uses 3g/2g, as well as yourself, the sound is still there.

I didnt test yet if same behaviour reproduces if your Sailfish phone is itself calling via volte as well as the reciever.

VoLTE has been enabled on this phone forever.

Yeah, but can you try calling someone that switches its network to ‘prefer 2G/3G’, as well as yourself? I think if one of the calling person uses volte, the beeeb sounds disappear.
