Windows 10 vs Sound
-
Not long ago I bought a Dolby Atmos capable soundbar, and I thought to myself "what a wonderful idea would be to hook it up to my Windows 10 PC". Today I know such ideas should be strapped to a concrete block and thrown into a river.
Let's start with h/w status: Atmos requires HDMI connection, so I needed to plug it into my graphics card; I have two Titan XPs, both having only a single HDMI port; I have two displays hooked via DP and HDMI. What follows is a complete procedure how to set everything up, established by few days of trial, error and heavy Slavic cursing.
- Disconnect the secondary HDMI monitor and plug the soundbar in. For some reason Nvidia decided that in SLI configuration, you can hook stuff up to both graphics cards, everything gets recognized, but only one card sends the data. Just because.
- Plug the secondary display to HDMI out of the soundbar. Now every time I turn the soundbar on/off, the screen flickers for a few seconds.
- Be sure to use the right HDMI cable. Apparently it needs a bit of pixie dust and unicorn farts to work.
- Install Dolby Access application.
- Change the drivers of the sound h/w from Nvidia specific to generic ones.
- Reboot.
- Lower the resolution of the secondary display by one notch.
- Change the drivers of the sound h/w back to Nvidia.
- Launch Dolby Access and let it open surround sound settings.
- Enable Dolby Atmos for home theater.
- Bring back the correct resolution of the secondary display.
- View some Atmos content and verify it works.
- Notice all non-Atmos content in the system stopped working (a bug introduced in Fail Creators Update).
- Disable Atmos.
- Kill yourself (optional, recommended).

@thegoryone I'm a bit curious to see how it works on Linux, but I'm too sober for that right now.

@gąska and Core i9 7980XE overclocked to 4.5. Take that!
-
@neighborhoodbutcher your PC costs more than my car.
Edit: OCd i9? Isn't this thing incapable of running even at default clock rate?
-
@gąska quite capable, although it's outputting ~400W heat on full load now.
-
@neighborhoodbutcher must be a different model. I heard of one (and back then the only) i9 whose internal design was such that no cooling was physically possible to cool it down because the outer body was not conductive enough to transfer heat away from cores.
-
@gąska you've heard both right and wrong - i9 has toothpaste for heat transfer, that's why I had it delidded. But even stock is capable of boosting > 3GHz.

-
@neighborhoodbutcher said in Windows 10 vs Sound:

Ah, yes, of course. A standard procedure in top-end CPUs.
-
@gąska don't forget replacing stock IHS with silver.
-
@neighborhoodbutcher why silver when you can have GOLD?

My new machine (ordered Christmas Day, delivered 3 January) has an i7 7820X(1) that is nominally 3.6 GHz, but "turboboosts" to 4.3 GHz on low core-count work.
(1) Eight cores, hyperthreaded, Skylake-X, 140W TDP. Backed by 32 GB of 3000MHz DDR4. I am very pleased with it, even at stock clocking.

I've seen (used) cars that cost less than my graphics card.
-
@dkf If you're building a 3-way SLI setup during the height of the bitcoin age you could probably get a small new car for less.
-
@neighborhoodbutcher said in Windows 10 vs Sound:
SLI configuration
I'm surprised that's supported at all, actually...
-
I don't have any fancy sound system, but my computer regularly mutes audio for a few seconds if I'm doing something remotely computationally expensive (like playing a video game).
I'm not sure if it's my computer or the speakers or the wires, but hopefully it won't set my house on fire.
At least when I'm recording the virtual sound card keeps working the whole time.

Good thing you don't need audio in a video game
-
@ben_lubar I have the opposite problem, where I always hear the game sound in my headphones just fine, but OBS Studio mangles the audio after I've been looking at a static screen for too long.

@pleegwat said in Windows 10 vs Sound:

I'm not. I'm not even talking about a card that is remotely close to top of the line. (When I got it, there was a very good water-cooled model that was significantly cheaper than most of the others with its performance level. But totally not designed for Dunning-Krugerrand mining.)
There are some truly shitty used cars out there.

Well, nowadays, that's just about all used cars...

To illuminate a large array of tiny lights in an aesthetically pleasing manner.

Don't tell anyone I told you, but it's actually secretly reprogramming your mind bit by digital bit...

@pleegwat Hilarious, but I'm not kidding. What workload does overclocking a single CPU help with in 2018? As opposed to just renting some cloud servers.

A single CPU's great at an HTTP request to google.com on how to find some logo artists.

It's helped our build machine for sure, especially the "cooking" portion. UE4 cooking has much to be desired, and their "iterative" mode is broken in many ways too...
Edit: And it's cheaper than renting cloud servers, that's for sure.
-
@tsaukpaetra It seems to me that most software that runs like shit (take Audacity as an example) runs like shit because it doesn't use more than one core. Maybe Unreal Engine is different? It uses all cores, but still somehow runs like shit?

If you want to run Dwarf Fortress at max speed, you'll want one core that's super fast and (optionally) another core that just kind of has to exist. You could probably get away with one measured in megahertz.

It uses all cores sometimes. Like, when compiling shaders, it launches one shader per core (or, virtual core, don't remember which). When cooking, it's very much a single-core thing, for some reason, but some of the IO is async at least.
here's some links if you're curious how I came to my decision.
Previously a warm-build and cook would take anywhere between 40 - 110 minutes on a Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz (2 CPUs for 16 effective cores), 128 GB Ram, and an Intel NVMe something-or-other for the project cache drive.
Now, the same process (thanks Jenkins for allowing that to transfer over somewhat reasonably) takes between 12 and 22 minutes, on an Intel(R) Core(TM) i5-8600K CPU 2.30GHz (1 CPU for 6 effective cores), 32 GB Ram, Samsung 960 M.2 SSD for the project cache drive.

Nearly all games in existence use no more than 4 cores. Most use 1 or 2.
-
-
@gąska Right, so the games should just rent some cloud servers.

It lets me save some money on heating in winter.

In my case:
- building
- rendering
- work in general

Fun fact - the last Far Cry crashes if you have too many cores.
-
-
@gąska what I wish is one that actually runs on my CPU. For crying out loud - do they keep a static array of mutexes inside which runs out of bounds, or what?
-
@neighborhoodbutcher why won't you buy a second PC, just for Far Cry?
-
@gąska he spent all his money on an impractical processor so can't afford another PC?
-
@jaloopa oh it's very practical. But for some shitly coded stuff like Far Cry, I have another one (and a few others for different purposes, actually).
-
@neighborhoodbutcher I'm pretty sure the total worth of all your computer equipment is comparable with the apartment I live in. And it's a nice 60m2, 3 room apartment in a large city, not far from city center.
-
@gąska fun fact - I actually counted it all up not long ago, and you are correct. But it the end, all this is worthless, because Windows 10 is shit and can't play Atmos like a civilized person!
-
Would a Display Port to HDMI adapter work?
-
@slapout1 nope, because someone in a stroke of genius decided DP is for display, so it won't support any fancy audio encoding.
-
I wish DP didn't carry audio signals. I've got two Dell LCDs that have built-in speakers that work through DP, and Windows randomly decides that one of them should be used as the default audio device instead of my 5.1 soundcard.
-
@ender even when you disable them in the sound properties dialog? I've not had a disabled audio device randomly be re-enabled in my experience.
-
@lb_ disabling audio devices is broken on Window, like pretty much everything else nowadays. The devices stay disabled unless something changes, e.g. driver update. I constantly get my audio turned over to crappy monitor speakers.
