Public bug reported: The 3,5mm jack of the ThinkPad USB-C Dock Gen2 does not output any sounds.
The USB Device is 17ef:30d1 Lenovo ThinkPad USB-C Dock Gen2 USB Audio On the software side everything seems normal, I see output controls and everything. As soon as this USB is passed through to a Windows VM and back, sound works. A quick look in snd-usb-audio gave no clue and I have no idea how to debug such things, but Windows seems to do some magic when initializing this device. That Initializations seems to be persistent until powerdown ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2102208 Title: Lenovo ThinkPad USB-C Dock Gen2 USB Audio does not output audio Status in linux package in Ubuntu: New Bug description: The 3,5mm jack of the ThinkPad USB-C Dock Gen2 does not output any sounds.
