Hello,

I am using focusrite audio interface to record the audio data with the portaudio library to record the sound 24/7 in odroidN2+. OdoridN2+ use aarch64 architecture. It can run the program for 3 hours and then hang with no error showing.

Therefore when I debug using sudo dmesg -l emerg,alert,crit,err, it gives the below messages

May I know is there any issue with my ALSA? If I want to check whether my ALSA is working correctly or not, may I know how can I check it?

Thank you. Yours sincerely, Susan

Use arecord to do the recording and see if you get the same results.

@Charxil - Were you able to resolve the problem?

The recording hang issue still exists but I no longer see the above error when the script is hanged. @philburk. I posted the new error in the #916 .
