No sound during normal (GSM) calls - both parties can't hear each other

Bug Reports
#1

REPRODUCIBILITY (% or how often): 50%
BUILD ID: 3.3.0.16, Device Adaptation 0.0.7.24
HARDWARE (Jolla1, Tablet, XA2,…): XA2 Dual SIM
UI LANGUAGE: English
REGRESSION: (compared to previous public release: Yes, No, ?): ?

DESCRIPTION:

There is no clear way to reproduce the error, however every now and then there is no sound during calls from the earphone or the loudspeaker. (Haven’t tried with headphones). The other party can not hear me either, it is like everything is on mute.
On the other hand Android apps like WhatsApp and Soundcloud work normally for calls or music. Also native apps like Received radio work ok and you can hear music from the loudspeaker.

PRECONDITIONS:

None

STEPS TO REPRODUCE:

  1. Call someone

EXPECTED RESULT:

Place a phonecall and speak with someone

ACTUAL RESULT:

Both sides are muted and can’t hear each other.

ADDITIONAL INFORMATION:

Reboot doesn’t help. The only way to recover from this situation is to run in terminal pkcon install pulseaudio and then reboot the phone. If you don’t reboot there is no change in the situation.

I seem to remember such question on TJC.
Did you search over there?

(and it happpened once to me but a reboot solved it afair)

I’ve found that if I take the SIM card out and restart a couple times, it eventually restores full functionality. I’ve also found this happens more when traveling and changing cell phone networks or to areas without signal and then back in.

Yes, you do remember correctly there are several similar questions but not 100% the same. After digging through similar articles from TJC I tried the “pkcon install pulseaudio” workaround which was mentioned for a different type of audio problem and I have been using it as a “solution” over the last few months. However given the fact that this problem can occur at random and there is no warning or any other indication that it is there in order to fix it until when you try to use the phone, I raised it as a bug on this new platform so it may get some visibility… It takes a few minutes to restore the functionality after the terminal + the reboots which makes the phone quite unusable as a phone. Every time you place or receive a call you go through the exciting (?) phase of “will it work this time around?”

Interesting observation, I will try to pay attention to these parameters too in the future

Sony’s phones seem to do this even when using android, can be found via google. My Xperia 10 has done this couple times, but for me shutting the phone down and starting it up again after few minutes has resolved the issue (ones I had to do it two or three times).
Has not happened for few month’s time.

Just ordered Xperia 10 plus dual sim, I wonder how bad that one will be. It will also run Sailfish.

I just had the same experience with my XA2 single SIM. It took 3 reboots.

I just installed SFOS X yesterday (XA2 single sim - H3113) and am also experiencing issues with sound during calls (or a complete lack of it). I really hope this will be addressed soon. Love the system otherwise.

My XA2 just did this (with 4.0.1.45 EA) for the first time, I’m quite sure. Mobile broadband went offline (it showed to work just fine but any browser wouldn’t load any pages) too, that was the first time for sure. I’m switching operator soon - the order has been placed - so I acyually suspect the old operator pulling a sneaky one on me. Or this is just a very unfortunate coincidence.

Oh well.

Keeping the XA2 Ultra turned off for a few minutes and cleaning the SIM card did nothing, thi more shutdowns later a rebiot fixed it… For now…

Edit: Forgot to mention that forcing 2G/3G/4G didn’t help, nor did airplane mode. My other phone with the same operator worked fine, so it wasn’t a hiccup in the network.

I observed the issue on my XA2 after upgrading to 4.0.1.45.

A reboot helped for me immediately, I didn’t try to change any settings before. Just rebooting.

#11

Rebooting helped for me as well.

Hello,
I witnessed this phenomenon way back, maybe exactly from 3.3.0.16, can’t remember.
This happened with XA2 and now with my current X10III.

However 4.5 version SFOS this was not THAT problematic as it appeared maybe once in a month, well, anyway not that often.

But with 4.6 version this is happening daily. And it really renders the phone useless. I can’t risk anymore with this frequency…maybe the voice doesn’t work just when I would need to call emergency services - who knows.

I reset this with > power off > hold both volume up and down pressed and then hold power button down until phone vibrates 3 times > voice works again. But this is not a drill what you can nor would happily do when somebody is dying next to you.

I’ll try to flash the phone again and see if it helps - and will report back if it did.

However, if it doesn’t help, I will need to flash Android on the phone hoping SFOS 5.0 will fix this (not holding my breath for it).

I have Xperia X10 III with SFOS 4.6.0.13
and yes, this might have something to do with bluetooth, not sure, but I’m witnessing this without BT also.

Is there another thread for this also? Didn’t find with short searching.

Have you tried the audio restart in settings->utilities?

#14

Are you aware of the thread of this post?

#15

I do not know if it is the very same issue or not, yet sometimes I may try to call somebody only to realise that the phone does not “toot” and, if they answer in the meanwhile, I do not hear them and they do not hear me.

I have pulseaudio installed (probably because of the now famous phantom post about the issue @peterleinchen mentioned) BUT it only takes me to open terminal, and as defaultuser to type

pulseaudio -k

and that has always been enough* for everything to work again, since I read about the solution workaround. No waiting, no rebooting.
*I also remember that in the post I had read, people used to restart pulseaudio until someone pointed out that after killing it, it would restart automatically. That’s been the case for me.

#16

Wasn’t aware/did’t remember that one. Thanks for the tip! I’ll surely try that out!

#17

Thanks! I wasn’t aware. I have to dig down to the Qcommand if Settings>Utilities>Audio system reset won’t yield results.

I am not using Android apps often, I don’t keep Appsupport on either most of the time.

I’m going to try bluetooth connections/disconnections with car and see if/when audio silences in the process.
