Can confirm the bug on HP Envy 15t-ew000. However I searched the web for a solution and it seems like someone on the hp forums might have gotten it to work by writing a custom patch for the kernel as given here https://lore.kernel.org/lkml/20220811053950.11810-1-faenkhau...@gmail.com/

Intel Tiger Lake- LP audio controller. When playing any audio, the internal speaker plays no sound except periodic loud crackling noise. The 3.5mm jack does not work either, producing the same craclking noise alongside some eletrical noise. HDMI audio skimmishly tested, but also gave no sound. Curiously, USB headphone (along with microphone) works perfectly, also the internal microphone. As attempts to fix the problem, I have tried the following separately, with no avail: - Installing some Ubuntu OEM version of the 5.17 kernel - Updating to the v2.2 firmware from Sound Open Firmware Project (thesofproject on github), reverted afterwards I found exactly the same problem reported in the Fedora community: https://forums.fedoraforum.org/showthread.php?328627-HP-Elitebook-840-G8-Tiger-Lake-audio-only-produces-popping-sound&p=1860086 As the pre-installed Windows has been destroyed, no further test on Windows has been done. Since USB headphone and internal microphone work, I think that there is no problem on the Intel Tiger Lake-LP controller and its driver. The bug probably lies elsewhere, like in the handling of ALC245 on this new laptop model. Thank you very much for your time and effort in advance.
