I am trying to connect my 64 bit Ubuntu 14.04 Dell Inspiron laptop to my Sony LCD TV with HDMI.
The video works, but the audio does not. It continues to give audio from the laptop, not from the TV. There is no problem with my TV as it used to work with another Dell laptop with Windows 7.
If i go to System settings -> Sound in Ubuntu, the HDMI device is not listed under output. But
aplay -l command does list out HDMI sound cards :
faizal@faizal-Inspiron-3537:~$ 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 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: PCH [HDA Intel PCH], device 0: ALC283 Analog [ALC283 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0
Here is what all i have tried to resolve :
Based on https://askubuntu.com/a/117773/279330, i tried :
speaker-test -c 2 -r 48000 -D hw:0,3
The test was successfull and the HDMI is now listed in sound settings. But the audio still does not output from the TV.
Then i try the instructions at https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS i.e. I install DKMS, download the ALSA package and then run
sudo dpkg -i <filename>.
But i get the error during install :
Selecting previously unselected package oem-audio-hda-daily-dkms. (Reading database ... 360224 files and directories currently installed.) Preparing to unpack oem-audio-hda-daily-dkms_0.201408161316~ubuntu14.04.1_all.deb ...

Can i try something to fix this?
