Hi all,
Ever since upgrading to Linux 6.4 HDMI audio has stopped working for me. I've tried it with the 6.1 LTS kernel and it still works fine, so it's not something else to do with my setup.
I'm using an HP Dragonfly Elite G2 laptop which has an Intel TigerLake SoC and I'm running the stock Arch Linux kernel (v6.4.6).
When I connect to HDMI, either directly via the laptop's HDMI port or indirectly via a USB 4 hub, while the display works fine, no audio will play over HDMI. Sometimes after attempting this, audio *also* stops playing correctly through the laptop's speakers (there's a lot of distortion). Audio works fine with my Bluetooth headphones.
Any ideas? Dmesg output below.
