No sound and file-manager dialogs crash

Tried to adapt your profile to my artix linux environment with no success.

Parent is shutting down, bye...

My profiles are in $HOME/.mullvad/mullvadbrowser but I already tried linking and/or moving the dir in $HOME/.firejailed-mullvad-browser

Did you use the install script? Mine are in $HOME/.firejailed-mullvad-browser/Data/.

[exchaex]

No I manually tried to adapt the script to the aur installation, but it was a mess to make it work.

So I decided to install it from scratch the official way.
Everything works out of the box except for sound. I don't have pulseaudio installed, only alsa.
No sound at all, .asoundrc is whitelisted and into .firejailed-mullvad-browser directory and there's no error in firejail output so I don't know the reason at all.
(I didn't edit the profiles, everything as default)
Any help? How can I debug this?

[exchaex]

Another weird issue, everytime I try to save a file/link it crashes, (--noprofile works for both dialog crash and audio).
Full verbose log
firejail --profile=firejailed-mullvad-browser "$HOME/Browser/start-mullvad-browser" --verbose --name="Mullvad Browser"
The only audio portion of --verbose log is:

The rest I assume is related to the save dialog crash.
