Ubuntu – Intel Sandy Bridge no sound through HDMI

11.04hdmisound

I am running Ubuntu 11.04 and I have an ASRock H67M-ITX/HT motherboard which is the Intel Sandy Bridge architecture.

I can't get sound to play through my TV on the HDMI interface. I have plugged in headphones and they work. I have also tried changing the device in sound preferences to the HDMI options provided

  • Digital Stereo (HDMI) Output
  • Digital Stereo (HDMI) Output + Analog Stereo Input
  • Digital Stereo Duplex (IEC958)
  • Digital Stereo (IEC958) Output + Analog Stereo Input

When I run the following command it plays sound fine. 

aplay -D plughw:0,7 /usr/share/sounds/alsa/Front_Center.wav

Best Answer

I remember logging in and logging out after plugging in the HDMI device and changing the sound settings to HDMI Output seemed to help in my case.

Additionally, running 'alsamixer' in terminal seemed to have made a difference before.
