Unable to get audio through HDMI connection to TV with Ubuntu 14.04
Solution 1
Just fixed my audio issues spent days updating drivers and it ended up being the most basic setting. Permissions, add yourself to the "audio" group. So pop out to terminal and execute the following command.
sudo adduser $USER audio
Hope it works for you as well. It's odd that you are not automatically in that group as sound is an essential service.
Oh, and reboot, just to ensure the permission kicks in.
Solution 2
Try these steps:
-
Install
pavucontrol
, if you haven't already, using the command:sudo apt-get install pavucontrol
-
Add your username to the groups
audio
,pulse
,pulse-access
,video
andvoice
using the following command:sudo usermod -a -G audio,pulse,pulse-access,video,voice $USER
If the command gives you errors on groups that don't exist, just ignore it.
-
Install the latest ALSA drivers using the following commands:
sudo add-apt-repository ppa:ubuntu-audio-dev/alsa-daily sudo apt-get update sudo apt-get install oem-audio-hda-daily-dkms
Reboot and check if audio over HDMI is working.

I was having same problem voice is not coming in TV after HDMI cable. I changed my sound setting after that it works perfectly. I changed my default sound setting as shown in image speakers to HDMI.

Solution 4
Try restart Puseaudio,
after the PulseAudio restart the device now displayed at configuration window.
See command:
pulseaudio -k
I added $USER to audio group too:
sudo adduser $USER audio

I'm having trouble getting audio through my TV which is connected via HDMI. The item is available (HDMI / DisplayPort 2) via sound settings, but it doesn't play any sound. I'm able to get the volume when logged in to Windows on the same setup.
I've tried updating my graphics card drivers through
Software & Updates > Additional Drivers
to NVIDIA binary driver - version 331.38 from nvidia-331-updates)I've done a couple of the things listed here: Ubuntu refuses to output audio via HDMI (installed
pavucontrol
, did the sound test on the highest voted answer), but they seem to be related to not even seeing the device listed, whereas I have the device listed I just can't get any sound.When I play through Speakers - Build-in Audio it works

Admin over 9 yearsWelcome to AskUbuntu! Could you list what program you are using to control your sound settings. (Not sure this will help, but more information is always nice)

Tom over 9 yearsWell, that worked... and, agreed, very weird you wouldn't automatically be in the audio group. Thanks for the help.
-
Nicu Stiurca over 8 yearsExcellent, thank you! Although, you can improve slightly by using
$USER
so that people can just copy/paste the command. -
rancho almost 8 yearswhat for those not having another sound card?

rancho almost 8 yearsI did it, but didn't work. Also why should it work?

nyxee almost 8 yearsdisabling my NVidia GPU is less acceptable.
