Hi wildfish, Thanks for submitting this bug and helping to improve Ubuntu.
This seems possibly related to bug 2156559, for a which a fix was released on 2026-07-16 as part of resolute/linux version 7.0.0-28.28. Please give this new version a try, and report if this resolves the issue you are seeing. If the latest kernel does not resolve the issue, please try the latest mainline build and report if you see the issue with that kernel version as well. This helps us identify if it has already been resolved upstream. Instructions for installing mainline builds can be found on this Ubuntu wiki page: https://wiki.ubuntu.com/Kernel/MainlineBuilds. ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2159581 Title: Audio regression: No internal speaker sound over sof-soundwire (headphone jack works) on Intel Panther Lake layout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2159581/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
