I use Realtek onboard audio, single 3.5mm jacked mic, HDTV/hdmi. I had an analog audio port issue when I changed video cards.
My impromptu guide on using your home PC with an HDTV, concerns HDMI ports and most likely Displayports and audio.
I cannot really prove any of this but I just took a journey along these lines and this is my conclusion.
HDMI>HDCP>PC this is the way things are now, copyright protection and new sec measures, but the consequences of poor ..................
We look at our monitors as peripherals of our PC's. The modern industry is looking at our PC's as a peripherals of the HDMI HDTV.
rule #1- doing a clean install of pc OS, thinking your getting ready for/building your new system with HDMI. Under no circumstances should you install that OS connected to any HDMI port. Get yourself and old CRT, Early flat panel, what ever. You want a simple vga monitor. Help your system imprint itself with the fact that you need analog audio. Then just unplug the old monitor and plug in the HDMI ported HDTV. Do not let it be discovered in the devices folder. You must then do the usual audio software choices selecting default devices yada yada.
rule #2-so you have been using an HDTV with your current card. It always worked, analog sounds worked from initial plugging. New vid card arrives, uninstall all vid card driver and software, same for mobo sound. Get an old vga monitor, under no circumstance should you activate that new vid card connected to a HDMI port. Strip out all the stuff, use the MS driver for your old vid card with a vga monitor. Getting system to vga helps telling windows to recognize analog parts, if your HDMI device was connected, windows would see only the HDTV's digital sound capabilities.
Once system is vga then install sound drivers, verify that all ports work. ie:mic ports
Install new vid card using the old vga monitor, let system imprint that new card with analog needs. You should now have your new vid card using the MS driver, vga, connected to a vga monitor with a working mobo audio system, in my case, again tyvm. Install vid card drivers, clean install. Verify working vid drivers and sound parts. Unplug old monitor and plug HDMI ported HDTV, verify. You will need to enter NVidia panel and select HDMI sound, enter manage sound audio and default the HDTV playback option.
rule #3- under no circumstances install anything concerning PC video connected audio systems connected to an HDMI/Displayport port. HDMI is digital it will take control and windows will make choices and the "vid cards audio chip will control", digital only. The audio chip on the video cards must be used to get audio thru to HDMI TV, my particular TV has no RCA jacks associated with its HDMI ports, digital signal strictly.
rule#4- new HDTV just showed up, this will be the only hardware change, current system monitor is dvi/pc port. Should be plug and play, the imprinting process, as I call it, is already done, ????????????????????????????????????????????????????????????????????????????????.
I only wanted to use my old 3.5mm jacked mic, whew, who knew.........................
........most of my understanding came from others. Merely my take on the whole deal. Its how these different devices handshake each other, they will try and dominate, you must control the handshake with low tech, then just add the high tech to established parameters.
HDMI>HDCP>PC= imprint, I cannot explain it really so I say imprint.
This appears to be a 1 time event, happens upon initial plug and use of video card. A decision is made based upon components detected, the vid cards in the middle of 3 devices. I had to put back my old card and let it take an imprint with the vga monitor, got sound working again. Then I removed old card and installed new card again, using vga monitor and with ms driver wddm 1.1. It imprinted the analog this time. Plugged hdmi, installed vid driver, joy all around.
