Audio Classification "Default" Device

[mrksmn]

Question/Issue:
I use “classify.py modelfile.eim” setup to run the audio classification in raspberry pi however sometimes when the reboot happened, microphone indexes were changing so that I could not directly run the code without selecting microphone index, what I want to do is always run with the “Default” microphone without asking me. But the writing indexes directly is not a solution because of the changing indexes of the input devices.

Hello @mrksmn,

I’ve noticed that in the past. See:

Raspberry pi audio classification default mic issue

Hello @vinaycs, Ok, I have an idea but not sure it will work in all the conditions, devices, etc… Run the following command: arecord -l You should see an output looking like this: **** List of CAPTURE Hardware Devices **** card 3: C920 [HD Pro Webcam C920], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 If you have a close look, it shows the hw id: card 3 Now you run the following command to get the ID arecord -l | grep "card" | cut -c 6 It will output 3 …

Hope that helps,

Best,

Louis
