can you paste output of
arecord -l (list of capture devices).
Which device you are using and os.
Does this instance is already open by default? like any video playing or something like that?

I am using a Plantronics USB Audio headset.
$ arecord --device hw:0,0 --channels 2 --format S16_LE --rate 44100Hz x.wav
arecord: main:722: audio open error: Device or resource busy
'arecord' command always fails the first time after system boot in my
system. But subsequent execution of the 'arecord' command runs fine.
I've attached the strace log for the "audio open error: Device or
resource busy" failure. Is there any fix available for this issue?
