Error while executing eIQ GenAI Flow Demonstrator on advantech aom-5521(iMX95)

[yuii13]

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

Currently we are using the SGTL5000 module, the system can detect it.

Is it possible to configure the default sound card?

Hi,
As outlined in the hardware requirements, the current demo is limited to EVKs equipped with the WM8962 audio codec. That’s why it doesn’t work with other codecs like the SGTL5000.

The upcoming release, planned for this quarter,  will lift this restriction and allow the use of any codec — stay tuned!

Thanks and best regards,
Pierre

this configure file is for audio card and device configuration, maybe you can try to set your own codec here

After modifying "audio_config.sh", another error message occurs

do you have any local DFAE support? currently, imx95 is still under prepordcution stage, I couldn't share any internal document or code with you, I suggest that you can contact local DFAE to get further support, and what new errors do you get? let me check if I can share anything here with you
