So I flashed lineage os 14.1 (20180105 nightly) on my moto g3(osprey) and now whenever someone calls me or I call them, they hear their own voice as an echo while I have no problem hearing anything.

Can anyone tell me what the problem might be and how I can fix it please ?

Well, my friends can hear 'double' sounds, kind of reverberation I think, but only when on Loudspeaker mode.

I am using a modified mixer_paths.xml for stereo output (but I didn't touch mic values) from 5/6th jan build. At first I thought I had messed up, but now it seems it's something in ROM/kernel.

Have you tried flashing squid kernel and then testing? The custom kernel had a fix for low call & media volume, so maybe it fixes up the current issue ?

I tried the squid kernel but the issue still exists. Any ideas how to fix this ?

Still doesn't work. I'm now on 26th Jan build and with Ultradevs 7.0 kernel. Help !!!
Try replacing your mixer_paths.xml with the one attached in TWRP. You can backup your current setup and try with a clean install to ensure that it's used correctly. I had modified this file to enable stereo output so please bear with that :)

Tried this, still doesn't work. :(
Is there any chance that this might be a hardware error ?

Finally I solved the echo problem in my XT1550 2GB phone.
------------------------------
FINALLY WORKING (echo problem SOLVED):

https://forum.xda-developers.com/2015-moto-g/general/index-moto-g-factory-firmware-images-t3169639
Download XT1550 5.1.1 stock firmwares
5.1.1 (build 47 ) = Retail Asia | India (2GB) - XT1550_OSPREY_RETASIA-INDIA_DS_2GB_5.1.1_LPI23.72-47_cid7 (Mirror #1)
5.1.1 (build 47.4 )= Retail Asia | India (2GB) - XT1550_OSPREY_RETASIA_DS_2GB_5.1.1_LPI23.72-47.4_cid7
5.1.1 (build 65 ) = Retail Asia | India (2GB) - XT1550_OSPREY_RETASIA_DS_2GB_5.1.1_LPI23.72-65_cid7 (Newer Build)

Steps I followed:

wipe/reset
install 5.1.1 (build 65)
install 5.1.1 (build 47)
Wipe/reset
modem firmware alone from OS5.1.1 (build 47.4)
Wipe/reset
modem firmware alone from OS5.1.1 (build 65), all other commands below in https://forum.xda-developers.com/2015-moto-g/general/guide-fastboot-flashing-factory-t3187750


fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem fb_mode_clear
fastboot reboot



(my guess is probably wipe/reset before modem firmware alone from OS5.1.1 (build 65) is the solution!)

Hope it helps someone.
