I have had the Philips 9030 Costco aids for about a year and they work well for me. I pair them to my OnePlus 8 smartphone through Hear Link and can stream audio and hear phone calls through the aids, but have to talk into the phone to be heard by the caller. I don’t know if this is the normal functionality, but it worked well enough that I never looked into it.
I updated the phone to Android 12 a couple of days ago and the microphone on the phone no longer picks up my voice during phone calls so I can’t be heard by the caller, but it does respond to my Google Assistant commands or Recorder input. I have ensured that the Microphone is enabled for my Google Phone app but it still doesn’t pick up my voice.
I disconnected the aids from the phone by turning off Bluetooth and then the phone microphone worked, so my assumption is that my phone or Hear Link is defaulting to the hearing aid microphone for phone calls when Bluetooth is on, but that the hearing aid microphone isn’t transmitting to the phone. With Bluetooth off, the phone relies on its own microphone.
OnePlus tech support hasn’t been much help so far, so does anyone have any ideas on how to restore the OnePlus microphone functionality while keeping my hearing aids connected via Hear Link? Obviously I could downgrade to Android 11 (the previous version), but I really don’t want to do have to do that.
