I'm not seeing any of the hw_params() issues with v4.1 - are you perhaps using an old linux-firmware? I don't know how up to date Ubuntu is there.
linux-firmware ubuntu 15.04 version: 1.143. This is based off upstream cef33368c4d3425f11306496f0250f8ef1cf3c1f, updated on March 4 2015.
That's the same firmware I have. Weird, I don't know if the Intel guys have any bright ideas here?
Hi Mario, can you try disabling pulseaudio to see if anything change? Once I got one XPS 13 9343, I can debug on it, we have ordered it, but been told still need wait 4 more weeks for lacking of the LCD screen materials.
