Im getting the below error when trying to record audio under the AI interaction using GPT-4O > voice communication section, please help?:
xxxx@raspberrypi:~/picar-x/gpt_examples $ rec op.wav
rec WARN alsa: can’t encode 0-bit Unknown or not applicable
ALSA lib pcm_dmix.c:972:(snd_pcm_dmix_open) The dmix plugin supports only playback stream
rec FAIL formats: can’t open input `default’: snd_pcm_open error: Invalid argument
Which version of the PiCar-X are you currently using? Please provide us with a picture of the robot hat.
Please use the following command to record audio and check the functionality:
rec -c 1 op.wav
Which microphone are you using?
I’m using the Picar-X v2.0
xxxxx@raspberrypi:~ $ rec -c 1 op.wav
rec WARN alsa: can’t encode 0-bit Unknown or not applicable

The USB mic which came with the kit
We were unable to replicate the issue you encountered.
We suggest that you try changing the USB port for the USB microphone and run the arecord -l command to see if the microphone device can be recognized.
Please provide us with the printed output.
Additionally, please follow the steps outlined in our tutorial:AI Interaction Using GPT-4O — SunFounder PiDog Kit 1.0 documentation
I have the same problem. I have the same error message. Under Google searches, for example, you can find something with “asym” and „dmix“ in the plugin.
I don‘t know if this same error.
Are you using the USB microphone that we provided?
Run arecord -l to check the list of available recording devices.
Confirm that your microphone is properly connected. We recommend trying a different USB port on the Raspberry Pi to see if it works better.
Please use the following commands to record audio and check functionality:
rec -c 1 op.wav
sudo play op.wav
Additionally, ensure that all required Python packages were successfully installed in the activated virtual environment without any errors.
Please follow the tutorial steps provided here:
