Created attachment 215561 [details] dmesg output Hi, I'm running ArchLinux on a HP x2 210 convertable, which is more a laptop with a touchscreen than a tablet, but can be used for both. I had to get Ubuntu 16.04 beta for being able to boot the live system flashdrive as both Fedora and ArchLinux couldn't boot from the flashdrive, there seems to be a problem with syslinux. Nonetheless, in both distributions the sound card is not detected: $ cat /proc/asound/cards --- no soundcards --- Afaik there is an intel on board soundcard in the tablet. To ensure the hardware works ok, I dd'ed Windows on the tablet again. It works there without problems. I got no idea what the problem could be, as I'm not familiar with sound devices at all. I attached the dmes output and the product specifications can be found here: http://h20195.www2.hp.com/v2/default.aspx?cc=at&lc=de&oid=8741507 Let me know if you need anything else. I appreciate your help a lot Thanks, Manuel P.S.: Currently I'm running on the zen-kernel. However, there is the same behavior on the mainline kernel version.
please try with a more recent kernel and if this doesn't work attach the DSDT and the output of cat /sys/bus/acpi/devices/10EC*/status

Hi, I tried out the latest mainline kernel with no success. The soundcard is still not detected: $ cat /proc/asound/cards --- no soundcards --- I uploaded the files you requested. Hope that helps. If you need more, let me know. Manuel
I think this is a duplicate from Bug 115531 The DSDT shows you have a Conexant cx2070 codec. can you give the output of cat /sys/bus/acpi/devices/14F1*/status If you see a value of 15 for 14F10720 then you are toast, Conexant does not provide drivers for Linux. Sorry.
There we go. Yes I have the 15 there. I sent them a mail to let them know that people are waiting for the missing drivers. But don't expect an answer.
Did you tried to kernel from this github https://bugzilla.kernel.org/show_bug.cgi?id=115531#c99 with UCM from this comment https://bugzilla.kernel.org/show_bug.cgi?id=115531#c68 Just in case, prebuilt deb pacakges is available: https://github.com/heikomat/linux/releases (but remember to extract UCM like this: https://bugzilla.kernel.org/show_bug.cgi?id=115531#c64 ) This kernel with this UCM works for me on HP Pro 608 G1, so I encourage you to try. If it works you, mark your bugreport as duplicate of Bug 115531.
