[SOLVED] no audio from browser / no sound to USB device

Hi all

this might have been more appropriate to post somwhere else on the forum
but will do it here instead as i am unsure .

after latest pacman update chrome stopped playback audio through external focusrite USB audio interface
and sound was coming from my internal laptop usb speakers instead.

here are some details from commands while issue was happening

#uname -a
Linux studiodahl 4.4.70-rt83-1-rt-lts #1 SMP PREEMPT RT Mon Jun 12 00:32:47 IST 2017 x86_64 GNU/Linux

( please excuse  the swedish bellow lol  )

# sudo fuser -v /dev/snd/*  #### before my "fix"
                     ANVÄNDARE   PID ÅTKOMS KOMMANDO
/dev/snd/controlC0:  digikwondo   3614 F.... pulseaudio
/dev/snd/controlC1:  digikwondo   3600 F.... jackdbus
                     digikwondo   3614 F.... pulseaudio
/dev/snd/pcmC0D0p:   digikwondo   3614 F...m pulseaudio
/dev/snd/pcmC1D0c:   digikwondo   3600 F...m jackdbus
/dev/snd/pcmC1D0p:   digikwondo   3600 F...m jackdbus

# sudo fuser -v /dev/snd/*  #### after my "fix"
                     ANVÄNDARE   PID ÅTKOMS KOMMANDO
/dev/snd/controlC0:  digikwondo  32331 F.... pulseaudio
/dev/snd/controlC1:  digikwondo   3600 F.... jackdbus
/dev/snd/pcmC1D0c:   digikwondo   3600 F...m jackdbus
/dev/snd/pcmC1D0p:   digikwondo   3600 F...m jackdbus

my fix was to click "stop" under "pulseudio" in Cadence https://kxstudio.linuxaudio.org/Applications:Cadence
but seeing new PID 32331 instead of 3614 i assume a restart operation was done of pulseaudio somehow.

could someone help me uderstand what happen here ? would good old "kill" command have had same effect on the issue ?
would be thankfull if someone could help me understand what happen there

If you want to prevent pulseaudio  from autostarting you'll have to mask its service
