I'm not an expert at all but I noticed these lines in my logs: When sound works:
Node 0x21 [Pin Complex] wcaps 0x40058d: Stereo Amp-Out [...] Pin-ctls: 0xc0: OUT HP When it doesn't work: Node 0x21 [Pin Complex] wcaps 0x40058d: Stereo Amp-Out [...] Pin-ctls: 0x00: OP has the first form. Would that mean that we are experiencing two different issues? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901926 Title: [HDA-Intel - HDA Intel PCH, playback] No sound at all from headphones To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1901926/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
