PyAudio Not Listing Devices Even Though aplay -L and Audio Playback Work on i.MX8M Plus

mn063 — Thu, 08 May 2025 12:31:02 GMT

Hi,

Context:
I have prepared an SD card boot setup for the i.MX8M Plus platform. My goal is to install PyAudio and run a real-time speech-to-text application using OpenAI's services.

While doing this

when i try to record or play an audio using the commands

arecord -D sysdefault:CARD=wm8960audio -f cd -t wav -d 5 MJ_recorded.wav

aplay -D sysdefault:CARD=wm8960audio MJ_recorded.wav

is working well

Below is the screenshot for sound devices listed using aplay

while,

trying to get the sound devices list using pyaudio i got nothing

(Installation done by usng pip install pyaudio)

code i have used :

import pyaudio

p = pyaudio.PyAudio()

print("Available Audio Devices:")
for i in range(p.get_device_count()):
info = p.get_device_info_by_index(i)
print(f"Device {i}: {info['name']}")

the above code doesnt list anything...

Kindly give me some suggestions...

TIA

Hello,

The PyAudio is not supported by default on our BSP. I suggest you confirm that have added the corresponding packages correctly to support this feature and contact software provider to troubleshoot this issue.

Best regards.
