Hi! I’m using /e/OS 1.17-s-20231113351092-dev-sunfish on Google Pixel 4a and getting the following problem: during the voice call the other person hears the echo of their own voice. The problem is present only in the conventional (default) voice mode, i.e: the voice of the other person goes to the speaker on the top (and to my ear). However, if I switch to the loudspeaker mode, the echo cancellation, surprisingly, works perfectly. What’s interesting, the same problem presents in other applications performing voice communications (Signal, for instance). And there, again, it can be “workarounded” by switching to loudspeaking mode.
I have a hypothesis, that the described problem can be solved by altering mixer_paths.xml (a fine-grained configuration of audio devices on Android, as far, as I know). However, I don’t know how to check that. What is the easiest way to alter mixer_paths.xml on /e/OS? What further investigations could be suggested?
Thanks in advance!
dev builds should offer adb root (if it’s not turned of for higher Androids for safetynet last I remember), then you can edit the mixer xml. I think it is a good hunch to go through the audio xml
Root access in dev builds sounds great. However, is it possible to install a dev image without clearing up the whole device? I. e. the same way as I install OTA updates? The device is in active use, so that’s a problem if I would need to clear up all applications and data.
but by your build string posted initially, you already are on a dev build? are you shown the root option below enabling usb-debugging inside developer options? (to enable those, tap 7 times onto the build string in settings → about-phone)
