    KDE Multimedia doesn't use the preferred sound device

    Hi, I use Fedora 27 64 bits, kde spin, updates installed.
    I have an USB headset plugged all the time to my laptop and have set it as the preferred audio output and input. However every time I launch a browser (firefox or chrome) and play some audio or enter a video conference chat, kde always uses the internal output/input, then I need to manually open the device setting, go to "Applications" tab and set the output/input device for each application, that is very annoying.

    As the USB device is set as "default" all application should use it instead of the internal one, right ? See attached screenshots, they are in portuguese. In the "Advanced" tab I set the option to automatically switch all running streams, see screenshot.

    For example, the image "applications.png" shows the music player clementine uses the internal audio, then I need to click the dropdown and choose the usb device.

    pacmd correctly shows the usb headset as default

    $ pacmd dump |grep default
    load-module module-default-device-restore
    set-default-sink alsa_output.usb-C-Media_Electronics_Inc._USB_Audio_Device-00.analog-stereo
    set-default-source alsa_input.usb-C-Media_Electronics_Inc._USB_Audio_Device-00.analog-mono

    Thanks for taking a time to read this.

    This article has useful information, where I need to call pacmd unload-module module-device-manager, then all applications uses the default device.
