HP Elite Slice with conexant cx20926 ALSA error

Hello guys!

l have a specific error regarding an x86 installed volumio. The hardware is a HP Elite Slice, which has an analog output and a conexant cx20926 output. The analog output outputs the sound to the pc speaker, and the cx20926 gives an error (Error: Failed to open “alsa” (alsa); Error opening ALSA device “volumio”; snd_pcm_hw_params() failed: Broken pipe.)
The PC should output to it’s integrated bang&olufsen speakers, which connects through the conexant option, not through the pc squeaker.
