I recently purchased a Tiger Lake laptop. It works for the most part, but there are some issues. I figured that the Intel distro would be the shortest route to getting this stuff fixed. Sound works, if I boot into Windows first and then warm boot into Linux. If I cold boot into Linux, sound does not function. In linux/sound/soc/sof/sof-pci-dev.c about line 240. static const struct sof_dev_desc tglh_desc = { .machines = snd_soc_acpi_intel_tgl_machines, .alt_machines = snd_soc_acpi_intel_tgl_sdw_machines, .resindex_lpe_base = 0, .resindex_pcicfg_base = -1, .resindex_imr_base = -1, .irqindex_host_ipc = -1, .resindex_dma_base = -1, .chip_info = &tglh_chip_info, .default_fw_path = "intel/sof", .default_tplg_path = "intel/sof-tplg", .default_fw_filename = "sof-tgl-h.ri", .nocodec_tplg_filename = "sof-tgl-nocodec.tplg", .ops = &sof_tgl_ops, }; sof-tgl-h.ri does not exist. sof-tgl.ri does exist and a different structure references it. The fingerprint scanner does not work. (Not that I use it.) It is an Elan Microelectronics Corp. ELAN:ARM-M4 and there appears to be no Linux drivers for it. (It is a USB device.) The video camera is not recognized. The screen does not adjust for brightness. (It has the new Intel video chipset.) I am willing to put in the work to get these issues fixed. (I have kernel experience.) I just need a pointer to the references needed to fix them. I can also test other people's fixes and/or provide information on the laptop.
