The sound for this laptop does not work without a patch to patch_realtek.c. I noticed that it has an ALC245 sound card, but a different product id. I have been running this patch for months and it works well. There is the known issue with the top-mounted speakers, but this is the same as when I manually run the hda-verbs as described on a forum post on kernel.org for similar models.
I added the following line: SND_PCI_QUIRK(0x103c, 0x89da, "HP Spectre x360 14", ALC245_FIXUP_HP_X360_AMP), Only the model 0x89da is different. I ran the diff command against a 62 kernel, but noticed that 63 has the same file and showed no commits.
I have been running this patch successfully for many months on the 62 branch, but I do not know anyone else with this same laptop model to confirm that it works for them.
If there is a different process for submitting the patch, please let me know.
Kernel 63 was just released for my distribution and I plan to test the patch there as well, but I do not expect it to work differently.
