Public bug reported: [Impact] Headset jack detection doesn't work on Dell UFF desktops. MSI interrupt doesn't work anymore if the HDA device ever gets runtime-suspended.
[Fix] Disable runtime suspend on HDA device. This is a temporary workaround, we are still finding the root cause. [Test] With the patch applied, jack detection always works. [Regression Potential] This fix will not enable HDA runtime suspend by defualt, so for systems that doesn't use TLP or `powertop --auto-tune`, this will slightly increase power consumption. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux-oem-5.6 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux-oem-5.6 (Ubuntu Focal) Importance: Medium Status: Confirmed ** Tags: oem-priority originate-from-1893610 somerville ** Package changed: linux (Ubuntu) => linux-oem-5.6 (Ubuntu) ** Also affects: linux-oem-5.6 (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux-oem-5.6 (Ubuntu) Status: New => Invalid ** Changed in: linux-oem-5.6 (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux-oem-5.6 (Ubuntu Focal) Importance: Undecided => Medium ** Tags added: oem-priority originate-from-1893610 somerville -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1897508 Title: Fix headset jack detection on Dell UFF desktops Status in HWE Next: New Status in linux-oem-5.6 package in Ubuntu: Invalid Status in linux-oem-5.6 source package in Focal: Confirmed Bug description: [Impact] Headset jack detection doesn't work on Dell UFF desktops.
