I have spent the last hour googling and digging and have found information ranging from solutions to problems I don't have to misinformation including "Windows XP doesn't support HDMI" , so hopefully someone here can help!
System:
COMPAQ Desktop PC Presario SR1650NX (you can see the specs here.)
I have added a GTX 650 Ti OC 2 GB video card to it.

I have connected it all via HDMI to my modern ASUS Tuf Monitor. The monitor ONLY has HDMI (x2) or DisplayPort. No VGA or DVI or whatever here. I have plugged speakers (and headphones- I've tried multiple devices confirmed as working on my other computers) to the audio jacks on my desktop. Obviously the HDMI is plugged in to the graphics card, I'm not sure if it works as a passthrough for system audio? And yes I know HDMI isn't necessarily ideal for an older computer, but I would very much like to not have to deal with a second monitor.
Anyways, "No Audio Device".
I have run Snappy Driver Installer (offline- the computer is not connected to the internet), all of the drivers are present and up to date. Every menu I find SAYS that the hardware is there and operating properly, but I have now followed the steps outlined in every list I could find online for fixing "No Audio Device" messages.
There are no volume controls or anything, most of the audio settings are grey. I have uninstalled and reinstalled drivers, disabled and enabled the Nvidia High Definition Audio, etc.
My concern is that the HDMI might be interfering in some way with the audio? Like it thinks it needs to use the HDMI for audio even though I'm trying to use the audio jacks, but there's nowhere to change audio devices at all since, well, "No Audio Device".
Let me know if I need to provide more information. Thanks in advance!
