Hi All,
$ cat /proc/asound/cards 0 [USB ]: USB-Audio - Plantronics .Audio 628 USB Plantronics Plantronics .Audio 628 USB at usb-0000:00:14.0-2, full speed
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?
You may check which other task blocks the PCM device:
lsof /dev/snd/pcmC0D0c
I guess that it will be pulseaudio (device enumeration).
