I had a look at my /proc/asound/card0 folder, and there are big differences between the non-working 5.6 kernel and the working 4.18 kernel.
In Kernel 5.6, in the folder /proc/asound/card0 there are 2 only folders, and 3 files. Folders: pcm0c pcm0p Both folders refer to the analog, for example the info file in the second reads card: 0 device: 0 subdevice: 0 stream: PLAYBACK id: 92HD81B1X5 Analog name: 92HD81B1X5 Analog subname: subdevice #0 class: 0 subclass: 0 subdevices_count: 1 subdevices_avail: 1 The three files are codec#0, codec#3, and id. (see the codec#3 attached) ** Attachment added: "codec#3" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834771/+attachment/5391376/+files/codec%233 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834771 Title: No HDMI-audio after kernel 4.15.-0.50 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834771/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
