Hello guys, I followed your discussion to try to solve my problem. Now sound works in my PC, but I've got some other problems that came with.
My PC is an Asus UX333FN, and I'm currently running on Ubuntu 18.04 with kernel 4.20. It came with 4.15.0.29.31 originally. When following the steps to install new kernels, above 4.18, I always get these messages : W: Possible missing firmware /lib/firmware/nvidia/gv100/sec2/sig.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/sec2/image.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/sec2/desc.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/nvdec/scrubber.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/sw_method_init.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/sw_bundle_init.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/sw_nonctx.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/sw_ctx.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/gpccs_sig.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/gpccs_data.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/gpccs_inst.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/gpccs_bl.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/fecs_sig.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/fecs_data.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/fecs_inst.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/gr/fecs_bl.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/acr/ucode_unload.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/acr/ucode_load.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/acr/unload_bl.bin for module nouveau W: Possible missing firmware /lib/firmware/nvidia/gv100/acr/bl.bin for module nouveau (This time I was trying to install 4.18 for example) As I said, sound works, but my problem now is apparently the NVIDIA Card (it has a Geforce MX150). Sometimes my screen and my mouse freeze, and I also get something like in the attached picture. I also need to press two times the Fn keys for it to start working, which didn't happen with the other kernel. Has someone faced the same problem?
