Audio stutter that stayed on the new PC.

Hello fellow gamers, I talk to you in a desperate time of need.

I also got the Audio lag issue about two weeks ago and I don't know what to do.
Short: My game used to run very well on mid to high settings and sound settings on high.

Then suddenly last week I tried to run a game and it was unplayable.
Whenever there was some sound for example, units shooting it lagged as hell and the audio stuttered very much.

My specs then were:

i7 2660k
MSI Mainboard with Realtek HD audio
Geforce 560 GTX TI
8GB RAM
Some rather old hard drives

I thought 'well okay, my PC is dying, it is not the newest one' because all my specs were about 2-3 years old (for me this isn't really a long time but I know that hardcore gamers switch their specs every year or so, haha)

So I first got a new graphics card and a SSD and another HDD. I removed the old hard drives because they were about to go down soon I thought.

New graphics card (970 GTX) and new hard drives DID NOT fix this problem.

So I thought 'okay well then the processor or the mainboard have a defect' because, you know, HD realtek audio onboard drivers.
I have to say that I also tested the game with a separate sound card from Creative. I disabled all HD realtek audio stuff in the BIOS and the device manager. DID NOT fix this problem as well.

Now my new processor and mainboard have arrived.
Newest i5 and Asus mainboard (again with realtek audio).

My RAM got checked several times and never any problem was determined.

In fact I have a whole new system. (Except RAM and my DVD drive, lol)
So I built it together yesterday and was pretty happy because logically a whole new System that is simply one day old can not have the same problem as the system before.

IT. DID. NOT. WORK!

Stuttering remains when audio settings are any higher than low.
On low everything runs more or less smooth (as you would expect it from CoH2 which is really not programmed very well).

But I don't understand it? How could it possibly start to stutter that much??
On the old system I did a complete reinstallation from DVD and downloaded all updates. Didn't help either.

In addition: The stutter also appears on League of Legends so it doesn't appear to be from CoH2 itself.
I also reinstalled Windows several times of course.

All drivers are up to date.

My new specs:

i5 4k something
Asus Mainboard with HD Realtek Audio
Geforce 970 Gtx
SanDisk SSD and Seagate HDD
8GB RAM (from the old system)

Please, anybody, help me.
I am so desperate

A lot of people with similiar issues reported that this program fixed their issues: www.tweaking.com

Also you could give this a shot:


"Go to Control Panel > Hardware and Sound > Sound > Playback tab.
Right click on a playback device, and choose Configure Speakers. The default is set to Stereo. I recommend choosing Quadrophonic if you do not have a subwoofer, and 5.1 Surround if you have a subwoofer connected. Go through the tests and confirm OK. Go through the rest of the playback devices.
Finally, re-confirm default playback device (even if it was already set as default device – by choosing a difference device as default first then re-selecting the intended default device)"

And some people got the issue fixed by disabling anti aliasing from coh2 settings

It's a problem with the sound card crashing. If you restart your system after every 'cold start' (when you turn the power button on), it shouldn't happen (so basically, do a cold start, as soon as you hit desktop, do restart, not shut down). I have to do this every day.

Let me know if it works.

I'd try a sound card instead of onboard.

I'd try a sound card instead of onboard.

Unfortunately I also did this and it didn't help :/

Did you do a clean install of Windows with the new system and drives? I'd hope you didnt image over the old one.

Did you replace the PSU?

OK I resolved the problem.

It was my own idiocrazy.
The last motherboard had a onboard sound issue so replacing it was the right decision.
The errors stayed the same because my CPU overheated. The reason for this was that I didn't pulled the screws of the CPU fan tight enough.

Now everything works fine again.

Thank you so much for all the answers though!
