Audio quality during phone calls on Xperia 10 II

REPRODUCIBILITY (% or how often): 100%
BUILD ID = OS VERSION (Settings > About product): 4.2.0.21
HARDWARE (XA2, X10, X10 II, …): X10 II
UI LANGUAGE: German
REGRESSION: (compared to previous public release: Yes, No, ?): ?

DESCRIPTION:

During phone calls the phone ear speaker produces the hum/buzz sound (known from a cellphone being placed next to an external speaker) for the complete time of the phone call. This sound is also heard by the receiver of the call on his telephone. Changing the sim card to another provider did not solve this problem. Also setting the network from 4G to 2G did not solve the problem. Signal strength is above 50% or much higher. This sound is not heard when making a phone call e.g. via Whatsapp.

PRECONDITIONS:

None

STEPS TO REPRODUCE:

  1. Make a phone call

EXPECTED RESULT:

Clear audio, similar to previous phones (e.g. Xperia X with Sailfish OS)

ACTUAL RESULT:

hum/buzz sound during phone calls

ADDITIONAL INFORMATION:

Maybe similar to Terrible sound quality during voice call when roaming - tested on multiple phones but not related to roaming.

I just bought a xperia 10 II and Im also having the exact same issue :frowning:
If I use the speaker phone functionality, person on the other end hears the same distortion.

I use a 10ii too, but for me the call quality is great. However, the people on the other hand of the line are complaining pretty often, and handsfree/speaker mode seems to be completely broken.

Are your Xperia 10 II phones single SIM (xq-au51) or dual SIM (xq-au52) models?

I am using the dual-sim model (XQ-AU52). Unfortunately, the problem still persists and even if the phone is reverted back to the Android operating system. Therefore, it might be a hardware problem as the noise is not hearable, when

  • a headset is plugged in

  • the phone speaker for hands-free talking is used

  • a Bluetooth headset/ car audio is used

Sony and the seller refuses a warranty repair and they wanted to replace the mainboard first. However, I am not sure, if that is the problem or if only the speaker/ internal microphone has a defect. Any suggestions?

Any News here. My Xperia 10ii make also during phone calls hum/buzz sound for the other site. I mean its a problem with the sensitivity control. Whenever I make a noise, the hum better buzz goes away. I will try to set the micro on 90% with pactl set-source-volume 2 90% and systemctl --user restart pulseaudio.service…
The embarrassing thing is, you can’t hear it yourself.

I have the noise with the dual SIM device (xq-au52)

I have solve this for me!
I changed the file “etc/pulse/xpolicy.conf”.
I add “, limit_volume” in line 131:
old:
129 [group]
130 name = call
131 flags = set_sink, set_source

new:
129 [group]
130 name = call
131 flags = set_sink, set_source, limit_volume
