I believe I'm hitting the same issue, albeit with a Lenovo Miix 310, which previously to upgrading to Bionic had working audio.
Attached is a log of what I get when I attempt to start pulseaudio with "pulseaudio -vv", and the list of devices and PCMs given by "aplay -l" and "aplay -L" respectively. ** Attachment added: "Archive of log files." https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1759942/+attachment/5155943/+files/logs.tzx -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1759942 Title: [HdmiLpeAudio - Intel HDMI/DP LPE Audio, playback] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1759942/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
