yesterday I set up my PC with Kubuntu 16.04 and all went fine except that there is no sound via HDMI. So I asked Google what to do, but I didn't find a solution for the problem.

That's the current state:

The output of aplay -l is

**** Liste der Hardware-Geräte (PLAYBACK) ****
Karte 0: HDMI [HDA Intel HDMI], Gerät 3: HDMI 0 [HDMI 0]
  Sub-Geräte: 0/1
  Sub-Gerät #0: subdevice #0

speaker-test -c 2 -r 48000 -D hw:0,3 shows:

Wiedergabe-Gerät ist hw:0,3                                                   
Stream-Parameter sind 48000 Hz, S16_LE, 2 Kanäle                
Verwende 16 Oktaven rosa Rauschen                                     
Fehler beim Öffnen des Gerätes: -16, Das Gerät oder die Ressource ist belegt

For non-german users: This means, that I can't use card 0, device 3 because it's busy.

When I run speaker-test -c 2 -r 48000 -D hw:0,7 I can hear the pink noise.

So I assume that there are some settings which have to be switched. But I don't know what and how. Can anybody help me? I'm grateful for any kind of hint!

Best regards Thomas


After updating to 16.04 I also had problems playing sound over HDMI. Up to now I had always been able to change the output with PulseAudio. Under 16.04 this option didn't appear anymore. After some clicking around I found a solution that makes this possible again. It's quite simple.

  • Click on the loudspeaker symbol in the lower right corner of the control bar.
  • Click on the settings icon in the upper right corner.
  • Click on Volume on the left.
  • Select the Advanced tab.
  • Here should be a built-in sound device out and a built-in sound device Analog Stereo Duplex.
  • Click on the button where it says Off.
  • Select an HDMI output.
  • Save.
  • Now the HDMI output appears at the Devices and there is once again in PulseAudio the button where you can adjust the output device.
