Bad Card or HDMI Cable?

[rexah]

I'm going to try and provide as much information that I think is pertinent please forgive me if I over/under-share. I wasn't sure where to post this I hope this is the right forum.

My issue is that when I output my audio through my TV that I use as a monitor a Samsung LN32A550P3F all audio constantly cuts out or has minor glitching. When I change the output device to my Astro A50's its fine. The monitor has been used in this fashion for years but I assembled my new build today and it's having this issue as a result of the new hardware I assume. All drivers are up to date. My device manager has four options in the drop down AMD High Definition Audio, ASTRO Wireles Transmitter, Intel(R) Display Audio, and Realtek HIgh Definition Audio. I have isolated it the controlling device to the AMD High Definition Audio Device. Reinstalled the drivers twice and still no luck. Any Insight would be much appreciated.

Build is as follows.
CPU: Intel Core i5-3570K Quad-Core Processor 3.4 GHz 4 Core LGA 1155 - BX80637I53570K
MOBO: AS Rock LGA1155 DDR3 SATA3 USB3.0 Quad CrossFireX and Quad SLI A GbE ATX Motherboard Z77 EXTREME6
RAM: Kingston Technology HyperX 8 GB (2x4 GB Modules) 1600 MHz DDR3 Dual Channel Kit (PC3 12800) 240-Pin SDRAM KHX1600C9D3K2/8GX
GPU: Sapphire Radeon HD 7950 3GB DDR5 HDMI / DVI-I / Dual Mini DP with Boost PCI-Express Graphics Card 11196-16-20G
HDD: Crucial m4 128GB 2.5-Inch Solid State Drive SATA 6Gb/s CT128M4SSD2
PSU: Corsair Enthusiast Series TX 750 Watt ATX/EPS 80 PLUS Bronze (TX750)
OS: W7-64

I dont think the gpu is bad.It is really good.Maybe your hdmi cable is old or somewhere broken.However the gpu could also have a problematic hdmi slot.Try by using the vga cable and attached on the vga port of your monitor.Good luck with this.

By further troubleshooting I have come to realize that if I plug my HDMI into the HDMI output on my mobo it's fine. Any thoughts? Also do I get the same quality output from my pc by doing this or is it preferable to go straight out of the Vid card?

Monitor doesn't seem to be the problem, I cannot help but think it's a driver/video card problem.

if you try with the realtek audio do you still have the same sound issue ?

 

[rexah]

If I send the audio through external speakers using the realtek it's fine, it's only when I try and send the audio over the hdmi with the video that the problem occurs. This problem is unique to this new computer as well. If I hook up to my other pc using the same hdmi cable/tv it works fine.
