No sound through HDMI

  • 772

I noticed that I can't send sound to my television when I connect my laptop to my tv through hdmi. I noticed that the hdmi is recognised, but I can't select it. I tried setting a profile to it, by using "Pulseaudio volume control" but no luck(image at the bottom of the post).

Here is the output from aplay -l:

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC269VB Analog [ALC269VB Analog]

  Subdevice #0: subdevice #0
card 1: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

The device is an acer aspire 7750G with specs:

  • AMD Radeon™ HD 6650M
  • i7-2630M

I am using this driver:

So what am I to do next?

Thanks in advance.

No luck

  1. To activate HDMI audio while using the open-source drivers edit the /boot/grub/menu.lst file and add this to the end of your "kernel" line:

    radeon.audio=1

    Also in terminal type this following command to update grub:

    sudo update-grub
