Question about HDMI audio [Nvidia]

So I don't actually have a problem, quite the opposite actually. I finally got everything set up perfectly in my dual boot with LM 19v2 and Windows 10. There is an absolute night and day difference in sound quality between the two OS's. LM19 blows Windows out of the water. It's clean, crisp, powerful. In a word: perfect. Windows sounds like, well, Windows. I'll get the occasional pop, fart, and fizzle. The best way to describe it is like Windows is a 128k MP3 and LM19 is a FLAC, if that makes sense.

PulseAudio was love at first listen.

So my question is, does my motherboard audio chipset have any impact on audio since I am running sound through HDMI on my Nvidia GPU? Or is it all in the Nvidia driver?

I'm curious because some driver is better on Linux than it is on Windows, just curious which one.

I also dual boot Windows 10 and Linux Mint 19. And I too have HDMI sound (albeit AMD). I think there's a second Realtek device as well. At any rate, you are onto something for sure, because more than half of the times I switch over to W10 and then boot back to L19 I have no sound at all and have to run two Terminal commands to repair it. The thread I made on it had appreciated input, but I still do not understand the fundamentals of why it happens. And so, there must be something intriguing about how sound works, considering you and me.

As a fellow Windows 10 / Linux 19 dual booter, I'll share this information with you as well: Dual booting has it's problems, albeit my preferred setup for a few reasons. 1. Window's clock became wrong each time I booted it. I solved this with a simple tutorial I Googled, which has you edit your Registry on Windows so that it'll use the same time method as Linux. 2. I've read that you want to disable 'Fast Boot,' that thing that makes Windows 10 seem like it boots fast when really it's just a trick and in actuality it simply never shut down all the way.

Now, as to why you would have superior sound quality on Linux compared to Windows, even though it's the same computer, I'd suspect your theory of the devices or setup being used better or worse by one OS over another is quite likely. Perhaps you can fiddle with settings on Windows to catch it up. If it's not just how Windows and Linux uses it (device/hardware/driver/etc.), or something neither upper nor lower level settings can change, then I'd suspect there's some sort of interference on the Windows side, even if it's something as simple as bulkier processing. But discovering the cause may not be easy, unless someone has learned of the answer already, then searching through a variety of logs like for your settings and statistics on each OS, may yield results, or not.
