Does it help? If not - revert changes by

Title:
No Audio from HDMI
I was able to work around this problem by using the xorg.conf option
"CustomEDID". The goal is to essentially tell the system to pretend that
your particular model of monitor/TV is always connected to the port in
question.
First, run this to determine the name of the video port in question:
i have the same issue too with ubuntu 16.04 mate, but also i have
changed my distro to Arch Linux and have the same issue, so i dont think
its limited to to Ubuntu.
The other issue is that the bug is intermittent. sometimes it happens
other times its not. I cannot work out what triggers this bug.
Same issue on Ubuntu 16.04 LTS with on-board Intel graphics.

On Ubuntu 14.04.1 LTS, another workaround is to go to the Display
settings and change the resolution of the (hdmi) display temporarily.
For example, set to a lower resolution and then let it time out (do not
accept the changes). The HDMI Play sound through option is then
available in the sound
Confirmed this bug with Ubuntu 12.04.2 LTS. Audio becomes unavailable
after HDMI television has been turned off.

I have a very similar problem, however, sound is not going through HDMI
but through internal analog audio to external speakers. When LG LED TV
is put on standby, there is no sound on external speakers. Box is used

Aaaargh. Commented in wrong bug, please ignore above. Sound is
working, just keys (volume up, down, mute) are blocked, not the sound.

same with intel on 12.10
it makes no sense to make HDMI audio out depend on active HDMI video
out, hell new HDMI cables even support ethernet, it makes no sense
concluding any media type with the cord/interface type.

For some reason gnome and cinnamon don't have this problem. I've
switched to cinnamon because unity had so many annoying bugs.

but can the newest driver work with 4XXX Radeon cards?
I hope the fix makes it to fglrx or there's a patch to the ATI drivers
that enables this to work. Pretty annoying to have to rs my HTPC very
time I go to view something.

I can indeed confirm that upgrading to AMD Catalyst 12.6 Beta fixed the
problem.
I build the .deb package from the install file using the internal build
process:
sh ./amd-driver-installer-8.98-x86.x86_64.run --buildpkg Ubuntu/precise
sudo dpkg --install fglrx_8.980-0ubuntu1_amd64.deb
sudo dpkg
Well this sucks for those of us with a not too old HD 4000 series card
as 12.6 is not compatible. I'm going to try going through older drivers.
Perhaps this was a regression in ATI drivers and not present in one of
the older versions.

It seems that this is indeed caused by AMD Catalyst driver. There is now
beta version of 12.6 which has the following fix:

I can confirm this bug, but i do not believe it is pulseaudio related.
I am experiencing the exact same problems with a new install of Ubuntu

I believe the problem is Kernel or AMD Drivers related.
