Hi,
I am on Gentoo Linux system.
I am trying to set up my soundcard so I can listen sound from multiple
application at once.
aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
pulse

I am running always Firefox web browser which uses pulseaudio:
"Since version 52, Firefox has made PulseAudio a hard requirement and
dropped support for direct output to ALSA. To enable sound in these
versions of Firefox enable the pulseaudio USE flag."
So when eg. I try to run this:
aplay -D hw:0,0 test.wav
I get this:
aplay: main:786: audio open error: Device or resource busy
How to solve this problem?
In this case what should I put into ~/.asoundrc to can listen sound
from multiple application at once?

Best, Pali
