I'm having this issue since I have activated the "Hotword detection from any screen" option in the Google Search: what happens is that when I activate the option related above, the microphone stops working for everything, it just works for "Ok Google" and everything you say to it, but it kills the microphone for everything else. I just realized that I was having that issue when I made a phone call and no one who I called could hear me... then I tried to send a Whatsapp voice message but it didn't recognize any word I said to it... Then I thought it was the "OK Google" option, so I deactivated for any screen and the microphone started to work like always, phone calls, whatsapp voice messages, everything the microphone was needed, it also works only with the "OK Google" from Google Search app activated.
Maybe this could be helpful:
I use the gString app and when I try to tune my instrument and the hotword detection from any screen is activated it says: "Failed to properly initialize the microphone of your device; the tuner will now close. This usually happens, when another misbehaving app is still holding a lock on your microphone, although it has already been backgrounded."
The question is, Does anyone have the same problem?? Is there a solution for that issue? I am using the official OMNIRom nightlies, I have installed the last GAPPS from PA-GAPPS, and of course I have updated them as they required it. I really love that option, it's very helpful for me. I will appreciate any help you could give me.
Thank you guys.
