There are similar questions and good answers on this forum. Unfortunately none of them addresses my problem.
I had perfectly well functioning sound system on the Kubuntu 14.10 on same hardware, but for number of reasons I decided to upgrade to 15.04. It was complete install (and not muon upgrade).
My situation is slightly different:
- all sound devices are showing:
tad@tad-desktop:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: PCH [HDA Intel PCH], device 0: ALC283 Analog [ALC283 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0
- Hardware revs (lspci -v) :

- I also apt-get remove and install alsa-base and pulseaudio and alsa force-reload
- output of alsamixer:

- Speaker test terminal output (no sound):

Any other suggestions from the community?
...So far no answer :-(
I have question to @nitzanms : what version of the kernel solved your No sound over HDMI running 15.04 on NUC D54250WYK ?
