Loudspeaker Sound
The sound is distorted when using the loudspeaker at a reasonably loud volume. There is a lot of reverberation, especially on specific frequencies, which I know from playing around with the output levels.
This noticeably started one day a few months after owning the FP4. I have run the audio test, and although I can hear sound from each speaker module Speaker 2 melody test is distorted, and Speaker 1 melody test is also distorHowever, all. All microphone tests appear fine, i.e. I can hear the rubbing noise.
Handsfree microphone
When on a call using the loudspeaker, the recipient has a tough time hearing me. The difficulty hearing me is more apparent on phone calls than on internet calls, perhaps due to the usually poorer sound quality.
These issues occur using both the stock FP OS and iode OS.
Has anyone else had these issues and know how to fix them or if replacement parts are required?
