So my audio stopped working after the upgrade to android 10. And I can not roll back to Android 9. Phone Samsung Note 9. Android 10.
Need help understanding the start-up process in android. Which file detects the chips, tells it which driver to load, and then logs the results after loading each driver. Which log should I look in for failures i.e. If I run Sound Recorder and hit record? The app just hangs. I cant click on stop. And can only kill it in notifications.
Like in Windows I can go to devise manager and see the list of drivers loaded and the status of each component. And if its failed it will say failed to load driver xyz.
If I have this info I can pinpoint which chip is acting up. I know the phone has one amp chip 98512 and one Audio Codec Chip. I want to know which IC is acting up or if its just a corrupted driver file. I did Odin the factory Image onto the phone. Just to be sure. Funny thing is Audio works in Blue Tooth but over the mic / speaker / ear phone jack all dead.
