I have to connect Respeaker 2mic pi hat to resberry pi 4 through python coding. I wanted to record and play the audio. Therefore, I combined the record.py and play.py from recording_example and tried to run. But, I need to confirm the device index i used this code "python3 recording_examples/get_device_index.py" from "https://wiki.seeedstudio.com/ReSpeaker_2_Mics_Pi_HAT_Raspberry/". The input device id is supposed to get similar to this "Input Device id 2 - seeed-2mic-voicecard: - (hw:1,0)" but I did not get instead what I got is given the form of picture here it is
when I randomly changed input device Id in program at some input id the programs runs but show this error given below. Please help me in this regard.
