Try the following in Ubuntu LTS 20.04, to clear things out. 1. Create a new gnome user and log in.
2. Build Rhythmbox 3.4.3 from source. This should take 15 mins + 200 MB disk space $ sudo apt-get build-dep rhythmbox $ sudo apt-get install git $ git clone https://gitlab.gnome.org/GNOME/rhythmbox.git $ cd rhythmbox/ $ git checkout tags/v3.4.3 -b v3.4.3 $ ./autogen.sh $ make $ shell/rhythmbox --version $ shell/rhythmbox Note: Here were just building and starting Rhythmbox from source tree. It runs 100% from the tree. We don't do any installation. So, this will not interfere with existing Rhythmbox installed by the system. Just always do this experiment as a new user, so config / data of both git and system Rhythmbox versions remain separate in separate user home dirs. 3. Check if the random sink issue shows up ( It SHOULD in my opinion ) 4. Do step [1] / [2] in Ubuntu 19.10 replacing "3.4.3" with "3.4.4". 5. Check if the random sink issue shows up ( It SHOULD NOT in my opinion ). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to rhythmbox in Ubuntu. https://bugs.launchpad.net/bugs/1883902 Title: rhythmbox ignores pulseaudio default sink and outputs sound on random device Status in rhythmbox package in Ubuntu: New Bug description: Ubuntu 20.04 LTS rhythmbox: Installed: 3.4.4-1ubuntu2 Candidate: 3.4.4-1ubuntu2 What I expect to happen : When I launch rhythmbox, I expect it to use the default pulseaudio sink. (Which can be defined in pavucontrol or with set-default-sink in /etc/pulse/default.pa ). What happened instead : when I launch rhythmbox, it outputs sound to a random device (in my case : either a RAOP sink in my living-room, or another RAOP sink in my kitchen. Never my local soundcard) If I correct the output sink (with pavucontrol or pactl) the problem is fixed... until I quit and restart rhythmbox. I did not have this problem with Ubuntu 19.10 / Rhythmbox 3.4.3-2ubuntu1 In 20.04 : -> Spotify (snap store version 1.1.26.501.gbe11e53b-15) has the same problem -> others apps I tested (Firefox, Chromium, VLC, Totem) do not have the problem I already tried to delete $HOME/.config/pulse with no improvement.
