@Sebastien, The kernel patches for cosmic and disco already got ack from ubuntu kernel team, and they are enqueued in the next release of kernel.
And it is safe to SRU alsa-lib first even without kernel patches. If the kernel doesn't contain those patches, the alsa-lib will work as before, the new added patches for alsa-lib will not introduce any side effect. And after the new alsa-lib is ready, I will build a kernel myself to verify it if the ubuntu formal kernel is not ready. thanks. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to alsa-lib in Ubuntu. https://bugs.launchpad.net/bugs/1806532 Title: The line-out on the Dell Dock station can't work Status in HWE Next: New Status in alsa-lib package in Ubuntu: New Status in linux package in Ubuntu: Fix Committed Status in linux-oem package in Ubuntu: New 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] For Linux kernel: Cherry-picked 3 upstream patches, these patches add the longname of the sound card for the dock station. For alsa-lib: Cherry-picked 3 upstream patches from alsa-lib, these will add ucm configuration files for Dell WD15&19, and change the SPDIF conf in the USB-AUDIO.conf. [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.
