I am running the latest version of KDE Neon. After installing updates yesterday and restarting my computer I no longer see any audio output devices in my system settings. A pulse devices is listed but I cannot play any sounds over it. I even connected a pair of bluetooth headphones but they don't work any longer and are not listed under the audio settings. See here for a list of screenshots: https://imgur.com/a/6XdjB Running `rm -rf .config/pulse && pulseaudio -k` makes a `Pulseaudio Server` available in the settings screen and lets me play music via internal speakers. I still am unable to connect my bluetooth headphones. I can see the following message in syslog: Mar 27 07:42:28 dell bluetoothd[1221]: a2dp-sink profile connect failed for 10:4F:A8:7E:2C:AD: Protocol not available
Somehow `pulseaudio-module-bluetooth` was missing on my system. After installing it I was able to connect my bluetooth headphones. Unfortunately I can only play using the HSP/HFP profile (which sounds very bad). When selecting A2DP via the Phonon Audio settings dialog nothing happens. Using a manual call to `pactl set-card-profile bluez_card.10_4F_A8_7E_2C_AD a2dp_sink` fails with status: 1
After uncommenting the following line in my /etc/pulse/default.pa everyhting went back to normal: load-module module-role-cork
