Apologies, I was not aware of the imgur thing. The new user did not have this issue. Only when I transferred over my plasma-org.kde.plasma.desktop-appletsrc config file did the issue show up on the new user. Some slop analysis is below. - Default output is a USB Focusrite. - Audio works and the sink is unmuted. - Plasma still uses the “no preferred sink/muted” fallback icon. - Restarting Plasma after audio initialization does not help. - Forcing a real default-sink change immediately fixes the icon. Plasma 6.7.4’s `PreferredDevice` constructor listens for future changes but never reads the already-existing default sink. https://invent.kde.org/plasma/plasma-pa/-/blob/v6.7.4/src/preferreddevice.cpp The larger layout changes when the volume widget is instantiated. If it is instantiated after the default-sink notification, it misses that notification and remains null indefinitely. Bug #521973 correctly identifies the null `PreferredDevice.sink`, but its proposed generic-icon fallback would only hide the misleading icon. The likely functional fix is initializing the values in the constructor: ```cpp PreferredDevice::PreferredDevice(QObject *parent) : QObject(parent) { auto server = PulseAudioQt::Context::instance()->server(); connect(server, &PulseAudioQt::Server::defaultSinkChanged, this, &PreferredDevice::updatePreferredSink); connect(server, &PulseAudioQt::Server::defaultSourceChanged, this, &PreferredDevice::updatePreferredSource); updatePreferredSink(); updatePreferredSource(); } ``` -- You are receiving this mail because: You are watching all bug changes.
