No Siri voice response over Bluetooth since iOS 15.5
Prior to 15.5, Siri would respond to long presses of the "voice command" button in my Ford. First, there was the initial 2-tone beep, I would speak, and Siri would respond to my command with voice.
Now, since 15.5, after a long press of the "voice command" button, I hear Siri activating with the 2-tone beep, I speak, and Siri doesn't respond with voice anymore. It seems like she's trying to respond because there is a delay (as if she is talking) until the next 2-tone beep (wanting me to confirm the command I sent Siri) or if the command requires no confirmation the Siri "session" with the car just ends.
Commands I speak to Siri all seem to work, but there is no interactive voice response from Siri over Bluetooth anymore... Just the familiar 2-tone beep prompts and silences...
So it seems Siri is working functionally, but the voice response is completely absent or completely muted.
