ALSA error running eiq_genai_flow with ASR

Hello,

I am getting the following ALSA error when running eiq_genai_flow with asr enabled:

./eiq_genai_flow -i kasr --output-mode text
Target Device: i.MX95

ASR model used: whisper-small.en
LLM used: danube-onnx

Both arecord and aplay are functional.

Here are the output of arecord:

arecord -l

Is there a way to configure the default audio card for eiq_genai_flow ?

Best regards,
Hervé

Hi Hervé,

This demo package is currently limited to i.MX95 and i.MX8P boards equipped with the WM8962 audio codec. That’s why it doesn’t work with boards using the WM8904 codec.

Unfortunately, this version doesn’t offer the option to change the codec configuration. However, the next release — planned for the end of Q4 — will introduce the ability to select both capture and playback codecs.

Thanks for your understanding, and best regards,
Pierre
