Windows 7: Audio stutter/lag whilst typing

Windows 7
Audio stutter/lag whilst typing

Hi all, searched for this but couldn't find any answers for my specific problem.

After installing Windows 7 64 bit yesterday, I'm very happy with it, but I've come across my first problem;

Whenever I type at any sort of speed (most of the time, I touch type), regardless of the software in which I'm typing, the audio seems to lag or stutter very slightly, as if input from the keyboard is too much for the machine to process. It's only noticeable when I'm playing music.

Perhaps I'm being a little lazy starting a thread this early, as I haven't yet exhausted all my options, but I'm curious to see if anyone's experienced the same issue and can save me some time. So far I've installed the latest Audio drivers I could find, to no avail. The next thing I'll try is to update my video card drivers, as it's currently only using the default win7 wdm one. I figure if the UI of Win7 uses hardware acceleration, it might have an issue there.

System specs, for reference:

CPU: AMD Athlon64 X2 4600+
Motherboard: Gigabyte GA-MA78G-DS3H rev. 1.0 (Realtek Azalia HD Audio chipset)
Memory: 2Gb DDRII 800
Video card: ATI Radeon 9800GT 512MB
Audio player: Winamp 5.55 (latest version)

It seems ATI's latest catalyst driver package for windows 7 doesn't list my video card as being supported, only the newer HD series cards, but I might give it a go anyway. Any other suggestions would be much appreciated, thanks.

Windows 7


I had this exact problem on my stationary computer which is now 100% SOLVED!

I used to run Windows XP x86 without any problem, with both overclocked CPU and not. After upgrading to Windows 7 x64 the problems started...

The solution was to upgrade BIOS to the latest version. I have a GA-965P-DS3 (rev 3.3) motherboard running an Intel Core 2 Duo E6420 @ 2,13 GHz clocked to 2,66 GHz. I had BIOS version F10, the website states in version F11 "Support Intel E6420 & E6320 CPU", i.e. my CPU.

So after downloading and flashing BIOS to the latest version, F14, everything works like a charm! No more choppy, jerky, sluggish mouse movement. No more jerky, slow moving windows. No more jerky browsing. No more glitches in sound or anything else while performing any kind of task in Windows 7.

I can also add that before the update I got the system to run stable in Windows 7 x64 by removing the overclocking, i.e. have the CPU run in it's native speed of 2,13 GHz. After the BIOS upgrade everything works great in overclocked mode also!

Good luck to all of you with this weird manifesting problem under Windows 7!

Follow up:

I fiddled around with the BIOS settings and discovered that if I Enable "SATA Port 0-1 Native Mode" the problem is back... After some testing I'm pretty sure this was the problem all along. Putting it back to "Disable" doesn't matter, the problem in Windows 7 remains. The only way to fix it again is to "Load optimized Defaults" from BIOS (which is what I originally did after the BIOS upgrade). This however definately solves the problem with jerky mouse movements and sound stuttering in Windows 7 x64 for me.

1. Load optimized defaults in BIOS (or equivalent for your BIOS)
2. Make sure the "SATA Native mode" setting is set to "Disable", i.e. it should run in "Legacy mode".

Again, my symptoms:
I experienced jerky mouse movement while browsing. If I had music playing (using Spotify or Webradio) the sound started to stutter just from opening a new tab in the browser, or scrolling up and down on a site, as well as the mouse movements being jerky. In programs which uses fades I got the same reaction. Moving a regular window around in Windows 7 could get me the same reaction. Turning Aero off and moving a window to the very top and then right/left continuously (the Windows 7 snap function) also gave me the same reaction.

All these symptoms are gone now!

Good luck guys!

Win7 Pro x64

I have this problem since the very beggining of my experience with Win7. First I thought just an RC (I used build 7100) issue, but two months ago I switched to non-RC pro and the problem persisted. I actually got used to it while listening to the music or watching videos :) But it makes playing action games harder. Tried many things, searched the web a lot (finding this thread finally), but the solution seems to be bloody simple:

Win7 x64 doesn't like my PS/2 port!

I left my old keyboard plugged into PS/2 and plugged another one into front panel USB, run some music in the Winamp and started typing in the Textpad. PS/2 stuttered, USB didn't. Then I unplugged my old keyboard from PS/2 and plugged the USB one there using an USB->PS/2 connector. Guess what? It started to stutter! Unfortunately I don't have a PS/2->USB connector, I'll try to buy one tomorrow and I'll let update the post. I hope it will work: I LOVE my old (8 years or so :) ) Adax keyboard :)

Am not sure if this could be due to KeyBoard drivers. You can check here :)

Ha! Problem solved! But it took some time. It turns out it is PS/2 problem for sure.

First I bought a normal, single PS/2 -> USB connector. It didn't work at all. Maybe that's because I accidentally sat on it :P When I went to the shop to change it I was offered another thing: double PS/2 (both keyboard AND mouse) to a single USB connector. Plugged it in - it works. And the "sound/video stutter when typing" problem is GONE! At last! After almost half of a year...

What's interesting about this connector is that it works in dos/BIOS without ANY problems! I have even disabled the USB Mouse and keyboard support in the BIOS and it still worked! Even when I changed the USB port while in BIOS - it worked right after connecting to the other one. I have to admit I was stunned, especially with the disabled USB support thing. The manufacturer is Gembird Europe B.V. in case someone wants to know.

Windows 7

I had same problem on my Acer Aspire 7738G Laptop. Seems like the internal keyboard was connected via PS/2 because i experienced same problem when typing on the internal keyboard, but not on a USA keyboard.

A BIOS update from V1.11 to V2.12 soved the problem:)

Thanks Jinrad.

I've had a Win7 Dell Inspiron laptop for a year and noticed the sound lag annoyance right away but only today decided to resolve it.

In my BIOS, I got lucky because I found an option to disable my external eSATA ports and that's what solved the problem for me.
