Changing video cards from GT 520 to GT 545 improved audio Tremendously?

[MarcMiller]

I have been tweaking my system by changing video cards I first tried a nvidia GT 430, then a GT 520 and was not able to hear any difference in audio quality. The next thing I tried was turning on the headphone surround effect in my VCL media player and got a very good increase in quality of sound through my old hi-fi which includes a powerful power amplifier and old Bose 901 speakers. I next tried nvidia GT 545 video card and the sound Improve phenomenally . The video card in particular I tried was the PNY brand using nvidia GeForce GT 545 chipset and 1536 MB DDR memory.

So what was the cause of this tremendous improvement in sound quality? Was it using the brand PNY for a video card? Was it GeForce GT 545 chipset ? Or the amount of hardware acceleration that video card has compared to the others I tried? (I had video acceleration overlay turned on in the VLC media player.) What happens is the dynamic range with my new arrangement seems tremendously better. Human voices sound much more realistic. You can also hear a tremendous difference when listening to piano's every note sounding very vibrant. So please give it your best shot and tell me why you think this is happening. I plan on building a new computer shortly and sound quality will be a major concern.

Are you sure you didn't put a new soundcard in the rig? JK.

The answer to your question is much more complicated than it sounds. I have a mechanical switch that switches between my local monitor that I am using when I type the answer to this question and my other monitor near my LG 42 inch television through a 75 foot equalized HDMI cable. I also have a some software called teamwork installed and another keyboard near my television. When I switched to my television as a monitor and use my better Bose 901 speakers the audio device being used in my television using the keyboard near my television to do what you just said is as follows "LG TV-1 nvidia high-definition audio device."

interesting. i assume the audio amp is too old to be connected to the tv via hdmi? so the amp is connected to what to get it's source? the computer or audio out of some type from the tv?

[MarcMiller]

The audio out of my television is a miniature size phone I plug believe 1/8 inch which goes to a Y.adapter with two RCA outputs. The input to the television is from one and of my 75 foot equalized HDMI cable the other end going to my video card through a mechanical switch which switches between the monitor by my computer and the TV used as a monitor.

I only glanced at this thread but I have my computer set up with standard 5.1 speakers hooked to the mobo via 3mini din and I have HDMI to my receiver. when I have my receiver on the computer will automatically switch audio devices (found under playback devices) from speaker to HDMI out. could this be what you are seeing (hearing)?
