Speaker phone microphone not working on Essential PH-1 regular calls & video calls
- /e/ version: 0.18-20210827132307
- Device model(s): Essential PH-1
- Device rooted: yes
Summary
Microphone does not work in speaker phone mode, including regular calls with speaker phone on or in video calls (e.g. Nextcloud Talk).
The problem
Steps to reproduce
- start/answer a call or video chat
- use speaker phone mode
- person on the other end of the call either cannot hear you or can hear faint mumbling
What is the current behavior?
Cannot be heard while using speaker phone mode, regular calls or video calls
What is the expected correct behavior?
Speaker phone microphone detects/transmits sound of a reasonable volume
Technical information
From reports this is the same undesired behavior on LineageOS on LOS 17 and I believe also on LOS 18. Appears to be related to the OS using the microphone on the back of the phone (normally used for noise cancelling) rather than using the microphone at the bottom. There were similar issues on stock android with PH-1 years ago, but I was able to use speaker phone without any microphone or other problem. Started immediately after flashing /e/os. This is not a duplicate of the Fairphone3 issues. Similar issues with Fairphone3 do not have a solution that is useful for Essential PH-1.

Do not know how to get this, will try to figure it out.

Solutions
Workaround
none known for video calls or speaker phone calls. can change audio source to 'Default audio source' for recording with microphone in Open Camera (go to settings within Open Camera -> Video settings -> Audio source -> Default audio source) -only works for Open Camera
Possible fixes
Editing the mixer_paths_XXXX.xml files in the /vendor/etc/ directory as mentioned here in the last (8/20/21) post.
