Sergey, your configuration file is working and audio is heard from qutebrowser on this system.
Internet searches surfaced commands like these, `pw-cli` `strace -e connect pw-dump >/dev/null` Error messages were seen relating to socket files not found, `$XDG_RUNTIME_DIR/pipewire-0` `$XDG_RUNTIME_DIR/pipewire-0-manager` Various things attempted, but the socket files missing every time sway started Finally, tried removing the pipewire-starting parts of the sway config ``` # exec_always killall -wqr "(pipewire|wireplumber)" \ # || sleep 1 && ((pipewire &); sleep 2 && (wireplumber &)) ``` Then separately started pipewire and wireplumber "manually" from the shell. The socket files were created and when qutebrowser sound could be heard. Thank you Sergey, Chris
