Yom - can you confirm what Bastien said in comment #5 about kernel 4.4? If not, he probably has different hardware to yours.
Can you also please test the 4.9-rc1 kernel when it is available at http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D It contains the following commit: ALSA: hda - Add the top speaker pin config for HP Spectre x360 HP Spectre x360 with CX20724 codec has two speaker outputs while the BIOS sets up only the bottom one (NID 0x17) and disables the top one (NID 0x1d). This patch adds a fixup simply defining the proper pincfg for NID 0x1d so that the top speaker works as is.
