Searched the mail list but nothing works: audio_alsa_sink[hw:0]: Device or resource busy

GNU Radio
1

When I want to connect the signal to the sound card, an error occurs as
below:

audio_alsa_sink[hw:0]: Device or resource busy
RuntimeError: audio_alsa_sink

I want the signal to be output to the sound card, but the card is in
use.
I tried lsof|grep /snd and kill -TERM the process in using sound card
pulseaudio, but doesn’t work.
Then I uninstalled the pulseaudio but the problem remains.

I also tried to set the sound sink device name to be: hw:0 / pulse /
plughw:0,0
none works.

Any suggestion?

Can you access the ALSA interface with any other audio application?
