Bug description:
[Impact]
On the Dell thunderbolt docs stations (WD15 and WD19), there are two playback
devices, one is headphone, the other is line-out, but there is no UCM for
these docks yet, so the pluseaudio only can handle the 1st playback device,
need us to add the UCM for them, before adding UCM, we need to set the
longname of the sound card in the linux kernel.
[Fix]
Cherry-picked 3 upstream patches, these patches add the longname of the sound
card for the dock station.
[Test Case]
Open the gnome-sound-setting, we can choose headphone-usb and lineout-usb from
UI, and play sound via these devices
[Regression Potential]
Very low, these patches come from upstream, and the change is only specific
to WD15 and WD19 dock station.
