I never got any sound out of it so far, but for the record, With Manjaro Linux and kernel 4.14 and 4.15, the sound card is recognized along with its HDMI outputs.
Although I haven't plugged anything on the HDMI port, from my readings I expect that it should work. However the internal speakers still don't, so I expect something from kernel 4.16 or 4.17 ;-) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1561278 Title: internal sound card not detected HP X2 Status in alsa-driver package in Ubuntu: Confirmed Bug description: HP Pavilion X2 - No sound card detected.
