My SYSTEM audio is delayed, when I get a notification there is no sound, but there is a background buzzing that tells me the sound has become active.
When testing sound I click Front Right all I hear is "right".

My issue is much like the one detailed here, except I'm using my GPU's HDMI output.

If I have pavucontrol open, the buzzing sound is constant and there is no delay. I hear all system sounds and notifications instantly.

In the above posted thread,user Dr.Evil posts a solution of disabling the audio module idle timer, which I think will cure my issue, but I can't figure out how/where the config document is to make the changes.

I'd also like to get rid of the low buzzing sound if possible,but that's not a real concern because it isn't too overbearing.

My system is:
Ubuntu 14.04 LTS 64-bit
AMD Athlon64 dual-core 4200+
Asus A8ZMN motherboard
2GB ram
Nivida GT520 /w proprietary drivers installed

I have pavucontrol,alsa-utils,and sox installed.

Open a terminal and type the following commands:

sudo nano /etc/pulse/default.pa

Press CTRL + w and type: 

load-module module-suspend-on-idle

then press ENTER. Change the line to say this instead:

# load-module module-suspend-on-idle

This is called "commenting out" the line when you place a # at the beginning of the line the configuration listed on that line will not be used.

Next, press CTRL + o to save the file and press CTRL + x to exit nano.

Finally, run the following command to restart pulseaudio:

sudo service pulseaudio restart
