The ECHO issue - Xperia Z5 Compact Q&A, Help & Troubleshooting

During calls the people can hear an echo of themselves. With a slight delay.
I have found this suggestion for changing making changes in the mixer_paths.xml.
Code:
<!-- Gain offset target for dmic1 unit calibration -->
<path name="dmic1-adj-gain">
<ctl name="DEC7 Volume" value="84" />
</path>
<!-- Gain offset target for dmic2 unit calibration -->
<path name="dmic2-adj-gain">
<ctl name="DEC9 Volume" value="84" />
</path>
Increasing DEC7 volume and decreasing DEC9 volume.
It doesn't quite do it for me. Can you suggest other values? Or other parameters that can be changed? Or maybe another fix?
Hope you can help.
Thanks.

I had the same problem. Do you have any issues with main microphone? For example, my main mic (down) is fine but my secondary mic (up) is broken => a lot of noise. You have probably the same problem as me.
You can try this value. I boosted the secondary mic and little bit decreased main mic. This edit not working good for me but maybe you'll have more luck.
Code:
<!-- Gain offset target for dmic1 unit calibration -->
<path name="dmic1-adj-gain">
<ctl name="DEC7 Volume" value="82" />
</path>
<!-- Gain offset target for dmic2 unit calibration -->
<path name="dmic2-adj-gain">
<ctl name="DEC9 Volume" value="129" />
</path>
This problem arising due to resonating phone body when you making a phone call. Main mic probably consider the sound from speaker as voice. I tried turn off noise reduction but still without any result.
Let me know if it helps.

I found new solution for this problem.
1. In path "anc-handset" you have to turn OFF ANC (Active Noise Cancelling).
Code:
<path name="anc-handset">
<ctl name="ANC Function" value="OFF" />
<ctl name="SLIM RX1 MUX" value="AIF1_PB" />
<ctl name="SLIM_0_RX Channels" value="One" />
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="CLASS_H_DSM MUX" value="DSM_HPHL_RX1" />
<ctl name="DAC1 Switch" value="1" />
<ctl name="RX1 Digital Volume" value="81" />
<ctl name="ANC Slot" value="6" />
<ctl name="ANC1 MUX" value="DMIC4" />
<ctl name="ANC1 FB MUX" value="EAR_HPH_L" />
</path>
2. In path "handset" you have to change RX1 Digital Volume to ~64 (it's general volume of speaker during phone call)
Code:
<path name="handset">
<ctl name="SLIM RX1 MUX" value="AIF1_PB" />
<ctl name="SLIM_0_RX Channels" value="One" />
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="CLASS_H_DSM MUX" value="DSM_HPHL_RX1" />
<ctl name="DAC1 Switch" value="1" />
<ctl name="RX1 Digital Volume" value="64" />
<ctl name="PM8994_Ear_Enable_States" value="Enable" />
3. If you have broken main mic (down), I will recommend increase dmic1 & dmic2. If main mic works fine I will recommend a little bit decrease dmic1 & dmic2 to ~80-82.
Code:
<!-- Gain offset target for dmic1 unit calibration -->
<path name="dmic1-adj-gain">
<ctl name="DEC7 Volume" value="82" />
</path>
<!-- Gain offset target for dmic2 unit calibration -->
<path name="dmic2-adj-gain">
<ctl name="DEC9 Volume" value="82" />
4. For camcorder is originally set the secondary mic. If your secondary mic is broken I will recomend change path "camcorder-mic-common" for main mic.
Code:
<path name="camcorder-mic-common">
<ctl name="AIF1_CAP Mixer SLIM TX8" value="1"/>
<ctl name="SLIM_0_TX Channels" value="One" />
<ctl name="SLIM TX8 MUX" value="DEC7" />
<ctl name="DEC7 MUX" value="DMIC1" />
<ctl name="IIR1 INP1 MUX" value="DEC7" />
</path>
<path name="camcorder-mic">
<path name="camcorder-mic-common" />
<ctl name="DEC7 Volume" value="104" />
</path>
<path name="camcorder-mic-gain-low">
<path name="camcorder-mic-common" />
<ctl name="DEC7 Volume" value="104" />
</path>
<path name="camcorder-mic-gain-mid">
<path name="camcorder-mic-common" />
<ctl name="DEC7 Volume" value="117" />
</path>
<path name="camcorder-mic-gain-high">
<path name="camcorder-mic-common" />
<ctl name="DEC7 Volume" value="126" />
</path>
I hope it will help
Sry for my Eng.

Thank you for the reply! I tried it and I believe it has worked to some degree. People can only hear themselves in the first 10 secs of the conversation after which it fades out. Do you know what could be the cause of this?
I did the microphone test and the main microphone was crisp, but the secondary was noisy.

nearly solved
hi. i'm new here, so sorry if i'm asking stupid questions
i tried these changes below on my z5c and it works much better than before. calling now is nearly normal, the echo is pretty gone! but now i have the problem that if i change to speaker during call the other one cannot hear me. anyone has a clue what the probnlem could be? does anyone know if the z5c uses the secondary mic when on speaker during a call? besides, i changed the value at mic 2 to zero.
wolud be happy if anyone can help,
greetings

As many unfortunate users of the Z5 compact, the other person during a phone call always complains about hearing an echo of their voice. After I switched from a stock ROM to Lineage it seems the problem got worse. I noticed that the ear speaker is louder under Lineage. When using headphones there is no problem at all. The phone is ****ty, whether it is the case, the speaker, or the microphone, it is a fu***ng phone this should work out of the box! Never mind about the screen quality or how smoothly the last Candy Boom Boom Extra runs, you expect the sound of the speaker not to leak to the microphone because it is how any decent phone has worked since Alexander Graham Bell :silly:
Anyway, thank you very much for the advice in this thread. I've had fun modifying the values from VI on a terminal in TWRP and it seems to have done the trick.... almost.
Here I wanted to contribute with how I experimented by myself without bothering anyone who posesses an actual telephone with a silly conversation such as "hi! me again... could you speak and tell me if you still hear yourself?".
You need to install Call Recorder from fdroid https://f-droid.org/en/packages/com.github.axet.callrecorder/
Then, just make a phone call to your voicemail and let the voice of the menu talk (or play stored voicemails).
Go back to call recorder and listen to the new audio file: you should now be living the hell your family and friends go through every time you call.
Tweak the values in mixer_paths.xml, then try again.
At some point you (almost) shouldn't hear the echo anymore.

Echo
Hello
Im new here and have this issue
Where can i found this xml file

---

I will test.
Thanks for advance.

---

I have test modification 1 and 2 on my xperia z1 compact. But echo is still the same.
Don't find lines of tweak 3 in my XML
Maybe my mic has material bug....

---

Tried everything ( multiple mixer_paths.xml end different roms ) without great success. In my case things go very bad when using headphones, it is like the phone is giving back his voice to the person I'm calling instead of mine.
It is clearly a software issue because it does not start immediately, but only a few seconds after the call begins ( at least with handset call ), while in the case of headphones I can make crystal clear calls with them on a old Moto g.
Any hint for the values to tweak? Is there maybe a bad working piece of software to turn off? Is the phone confusing mics and audio tracks?
It's such a waste having a good phone which is so bad at doing the most essential thing that a device has to do.

---

So, it seems that the very same problem affects also some other devices.
Here is fairphone:
Taiga
Taiga is a project management platform for startups and agile developers & designers who want a simple, beautiful tool that makes work truly enjoyable.
bugtracker.fairphone.com
In their case they solved switching from qcom echo cancellation ( which was bad implemented ) to the echo cancellation provided by android itself.
Could it be the same issue with z5s?
Here is how it is implemented in Google Pixel 3:
audio: enable AEC and EC audio effects · LR-Devices/[email protected]

github.com

---

Maybe I have solved the issue. So, as far as I understand the problem is a that acoustic echo cancellation fails to work properly, so I tried to disable it and let work only the sony one. In audio_effects.conf i commented aec and ns ( noise suppression, maybe this is not necessary ):
Code:
loudness_enhancer {
library loudness_enhancer
uuid fa415329-2034-4bea-b5dc-5b381c8d1e2c
}
# aec {
# library audio_pre_processing
# uuid 0f8d0d2a-59e5-45fe-b6e4-248c8a799109
# }
# ns {
# library audio_pre_processing
# uuid 1d97bb0b-9e2f-4403-9ae3-58c2554306f8
# }
sonyeffect {
library proxy
uuid af8da7e0-2ca1-11e3-b71d-0002a5d5c51b
libsw {
library sonyeffect_sw
uuid 50786e95-da76-4557-976b-7981bdf6feb9
}
libhw {
library sonyeffect_hw
uuid f9ed8ae0-1b9c-11e4-8900-0002a5d5c51b
}
}
Needs more testing, but the echo is just gone, and the call audio quality also seems way better.
I'm using LOS 14.1, with the default mixer_paths.xml as I think that the problem was not there.
Afaik after Android 9 there has been some changes in audio configs file ( now there is also an audio_effects.xml besides audio_effects.conf ) so idk if this very same trick works for versions other than Nougat, but I should be easy to implement an equivalent way.

There have been changes, yes. But the xml file replaces the outdated conf file: Klick
I don't know if the xml file can bee changed this way. I mean, if those changes should have any wanted effect.
Give it a try.

I see. Maybe we could just remove these entries:
Code:
<effect name="aec" library="audio_pre_processing" uuid="0f8d0d2a-59e5-45fe-b6e4-248c8a799109"/>
<effect name="ns" library="audio_pre_processing" uuid="1d97bb0b-9e2f-4403-9ae3-58c2554306f8"/>
in xml file.
Another way could be to replace aec libraries with the others that are commented in default conf file, (switching from audio_pre_processing to pre_processing,. From the default conf:
Code:
# Default pre-processing effects. Add to audio_effect.conf "effects" section if
# audio HAL implements support for them.
#
# agc {
# library pre_processing
# uuid aa8130e0-66fc-11e0-bad0-0002a5d5c51b
# }
# aec {
# library pre_processing
# uuid bb392ec0-8d4d-11e0-a896-0002a5d5c51b
# }
# ns {
# library pre_processing
# uuid c06c8400-8e06-11e0-9cb6-0002a5d5c51b
# }
It might be interesting to note that on pie usually audio_effects.xml has those lines in the end ( here is Fairphone2 as an example ):
audio - device/fairphone/fp2 - Gitiles
Code:
<preprocess>
<stream type="voice_communication">
<apply effect="aec"/>
<apply effect="ns"/>
</stream>
</preprocess>
</audio_effects_conf>
While here is nougat version for the same device:
audio - device/fairphone/fp2 - Gitiles

---

For those who want to test:
In @Berni-0815 repos you can find audio_effects.conf ( for 14.1 ) and audio_effects.xml ( for 15.1 and later ).
Change branch to select the correct version.

If your phone is not rooted you have first to edit files with a text editor, then from twrp set the right permissions ad copy the file to destination.
-Reboot to recovery
-Mount /system/
- Advanced => terminal
set permissions:
Code:
chmod 644 /sdcard/yourfile.xml ( or conf )
chown root.root /sdcard/yourfile.xml ( or conf )
copy it to the right location:
Code:
cp /path_to_your_file.conf /destination_path.conf
in destination the file has to be named as the original
eg in 14.1 is
Code:
cp /sdcard/yourfile.conf /system/vendor/etc/audio_effects.conf
#in 15.1 the path differs a little but you can easily find it with twrp file manager
If you have a rooted phone you can just edit the with a text editor on your phone or copy the file with a terminal.
Reboot and it is done.

I really can't help you because I don't know enough of these mechanisms.

Hello
I'm suffering from a strong echo of the X compact (which happens to the person I'm talking to)
I have audio_effects.xml in system / vendor / etc and vendor / etc
Which audio_effects.xml should I edit?
Please tell me so that beginners can understand
If you don't mind, please.
I'm sorry
I forgot to say
The device has lineage-17.1 installed.

---

The audio_effects.xml of no echo Z5 compact (lineage17.1 of thanks to Berni-0815)
Can I copy it to X compact?
Please forgive me in a stupid question of the beginner.

---

I'm not an expert actually, but you should look for sources of your phone or you can copy the xml file to your sdcard and then on your pc and see if it is the same. Even if not there are anyway chances that you can try a similar trick.
