~mesouug I've tested my XPS 9700 on the self-compiled ubuntu kernel, and it works great with a 4-pin plug, even the microphone input of the headset is fully functional. There may be hardware differences within the XPS 9700 line as well, but the driver must be fully functional for at least some of the hardware sold.
Are you confident your headset should be compatible? Not all 4-pin headphones have the same pin order, which was historically a common problem. -- 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/1924685 Title: No sound output/input available after installing 21.04 Status in OEM Priority Project: Won't Fix Status in Release Notes for Ubuntu: Fix Released Status in linux package in Ubuntu: Confirmed Bug description: Image: Hirsute 21.04 (20210415 daily build) Device: Dell Precision 5750 After installing 21.04, the sound card is unavailable.
