Hi Hui Wang, just wanted to remind you that this patch (meant for better usability) broke audio completely for many users out there. I'd really like to see any progress in the corresponding bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834771
Meanwhile I came across many threads in my local language ubuntu community forum that deal with exact this problem. Having no sound at all is a mayor deal breaker for many new ubuntu users that switched from Windows 7. So please, if a real fix needs more time, revert this patch in the first place! Having some superfluous outputs for selection is better than having no audio at all. Thank you very much for your time! -- 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/1827967 Title: There are 4 HDMI/Displayport audio output listed in sound setting without attach any HDMI/DP monitor Status in HWE Next: Fix Released Status in linux package in Ubuntu: Fix Released Status in linux source package in Bionic: Fix Released Status in linux source package in Cosmic: Fix Released Status in linux source package in Disco: Fix Released Bug description: [Impact] In our OEM projects, we often meet this issues, there is no any monitor plugged, but in the gnome-sound-setting, there are 4 hdmi/dp audio devices.
