Hello
Im not sure if this will help you or not, but I was having a similar problem after updating to iOS16 and fixed it by changing the options for my category.
As mentioned in your first block of code, I set the category, mode, options at the same time. Category is PlayAndRecord, mode is voiceChat and options are allowBluetooth and mixWithOthers. Speaker button didnt work until I added allowBluetoothA2DP to the options. Not sure why that worked ( maybe Apple bug ), but havent had problems since
