Attaching the patch itself, in case it helps — it is already upstream, so this should be a straight cherry-pick rather than a new backport.
It is Charles Keepax's "soundwire: dmi-quirks: Disable ghost Realtek devices", posted 2026-05-20 as patch 3/3 of "Update some topology matching for newer laptops": https://lore.kernel.org/linux-sound/[email protected]/ The SHA in the "From:" line is from my local tree (I had cherry-picked it there while debugging), not the upstream commit id — the content is the upstream patch unchanged. The diff is 35 lines: an adr_remap table (ghost_realtek) plus three DMI entries, one of which is exactly this machine: DMI_MATCH(DMI_SYS_VENDOR, "LENOVO") DMI_MATCH(DMI_PRODUCT_NAME, "83QK") Since my copy is based on a slightly newer tree, the context may not apply to 7.0.0 as-is, but the only hunk that matters for this bug is the one adding the 83QK entry to adr_remap_quirk_table[]. ** Patch added: "soundwire-dmi-quirks-ghost-realtek-83QK.patch" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2168633/+attachment/6002977/+files/soundwire-dmi-quirks-ghost-realtek-83QK.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2168633 Title: [Lenovo Yoga Air 14 (83QK)] No sound card at all on 26.04 kernel 7.0.0-34 — missing "soundwire: dmi-quirks: Disable ghost Realtek devices" backport To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2168633/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
