I have a similar set up and issue. I've plugged in my headphones and the "dongle" into my headhpone and mic jacks on my sound blaster Z. No sound when I first install Kubuntu. I default to using headphones.
I disabled the onboard creative audio in the BIOS when I first purchased the system with the sound blaster Z. The onboard audio does not show up in Kubuntu (expected). The Nvidia HDMI sound ports are both seen and take priority. I cannot change the priority order in the volume control gui. Also, there are no other mixer options except for a very basic slider in the volume control gui (Pulse Audio). If I run the alsamixer app from the command line and unmute the headphones I can head sound. In order to save my configs I have to use the alsactl store command. All of this is an inconvenience and not the end of the world. That said, it would be nice to have more volume sliders in the Pulse Audio GUI and change the priority of the devices so that HDMI is not seen as the primary device. -- 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/1741107 Title: [Alienware Area-51 R2, Nvidia GPU 71 HDMI/DP, Digital Out, HDMI] Playback problem Status in alsa-driver package in Ubuntu: New Bug description: Both the headphone jack ports(front and back) do not work.
