Using square card reader with voiceover

iOS & iPadOS


So, I have a square card reader that connects to my phone using the lightning port, but I found voiceover doesn't read anything when the reader is connected. when I have my braille display connected, I get braille output from voiceover but not speech output. I've tried looking in the audio settings of voiceover, and there's nothing to switch the audio channels to have speech come out the speaker on the phone. I even tried connecting a pair of bluetooth headphones to see if that would work, but nothing. Is there any suggestions that might work with this?
