After buildroot ffmpeg compiled with insdev alsa, the ffmpeg cannot detect alsa capturing card.
example command : " ffmpeg -f alsa -i hw(card # ) capture.wav" , it has alsa input/output error even if arecord is working fine.

Hello, the information you provided currently cannot determine the problem. Please provide the model of your Luckfox Lyra device, the audio interface, the sound card model, and the abnormal output log of ffmpeg.
