[solve] dual independent gpu (intel arc & nvidia) no audio

Hi sirs
I have two independent gpu, and if i use alsamixer to change default sound card and use under command it can speak out form different gpu 
   aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav   =>  intel speak out ok
   aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav   =>  nvidia speak out ok

And I refer web to add somf file  like   /etc/asound.conf   in  /etc,   and  ~/.asoundrc .   
                  (i prefer use intel)
                      defaults.pcm.card 0
                      defaults.pcm.device 3
                      defaults.ctl.card 0 

but in pavucontrol, it only show dummy output,  and  it looks like work normal volume can adjust
what can i do to next step?? ( i already join user to audio group, i use xfce)
information like list

grep -i vga

Re: [solve] dual independent gpu (intel arc & nvidia) no audio

replace pulseaudio w/ pipewire-pulse, probably drop pulseaudio-alsa

On a formal note, please use [code][/code] tags. Edit your post in this regard.

Hi, Sir

Thanks for your help! 

I remove pulseaudio,  install pipewire-pulse & pipewire-audio than to volume control => item configuration original no pro audio to choice,
                         after install it can change  dummy volume to pro audio
