Lync 2013 with Windows 8.1 unusably slow

Hi, I have a Windows 8 Enterprise (VL) laptop with 64-bit Office 2013 installed on it.  A couple of days ago I updated my laptop with Windows 8.1.

That seems to have upset Lync.  It has slowed dow so much as to be unusable.  For instance, if I open a conversation with someone and type something into the input area, my characters appear there with a 5 to 10 second delay per character.  For instance if I type 'hello there', it will take between one and 2 minutes before all the text is in and visible (and that is not because I am a slow typist :)).

Connecting to a video conference just locks the whole thing up.  Which is a problem since I have just signed up to a training course which is delivered via Lync.

Only a handful of other people in my office have upgraded, but none of them have the same problem.  Has anyone else come across this?  Or have any suggestions?  I have uninstalled and reinstalled Office but it made no difference.  I have also checked that my machine is up-to-date with Microsoft Update (both via WSUS and direct with MS).

Regards, Andrew

Hi,

Based on my research, I suggest you try the following method to see if it works:

Delete user profile with the path: %UserProfile%\AppData\Local\Microsoft\Office\15.0\Lync

Meanwhile, let us test clean boot mode to check the issue.

Hi,

For the issue,lets temporarily disable Windows firewall and security software to check if that helps.

Also,I suggest you login the other account to test it.

If the issue persists,I suggest you use lync 2010 client to see if it works.

Hi Kelvin, thanks for the response.

Before I saw your comments, I had made some progress towards identifying the cause.  It seems to be related to my sound drivers.  If I uninstall my Dell drivers (an IDT driver, dated March 2011), then Lync works perfectly.<o:p></o:p>

The problem I then have though, is that my system no longer recognises my headphones.  If I go into the Sound settings, it does not seem to recognise that my laptop has a single combined audio+mic jack plug it thinks I should have separate ones.

Unfortunately, there are no more advanced drivers available on the Dell web site.

So I have Lync working again, but at the cost of being able to use my headset.

I will follow your advice and give the Lync 2010 option a try.

Thanks for Your solution!

I have a same problem. When i upgraded my Dell Latitude e5520 from Windows 8 to Windows 8.1 the Lync 2013 client changed etremelly slowly.

I tried Office repair, etc. - Lync was extremelly slow.

Then i read this thread and i uninstalled all audio drivers - Lync works perfectly.

I found this list:

Just go to your speakers/Headphones properties and click on Restore Default. This will fix your Lync speed.

This only works temporarily for me. It seems like plugging, unplugging headphones is causing the issue to come up again. Has anyone found a more permanent solution?

I have the same problem.  If I plug/unplug headphones (with builtin mic), Lync becomes unresponsive.  Once I restore the defaults for the playback and recording devices, it fixes it.

Not a great solution as this happens A LOT.  I am gonna try uninstalling the IDT Audio drivers, and fall back to Microsoft's drivers, and see if that helps.

I just actually found an update for the IDT driver from the Dell support web site: http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=C6HVR&fileId=3327984030&osCode=&productCode=latitude-6430u-ultrabook&languageCode=&categoryId=AU

This resolved my problem as well. Uninstalled IDT Audio, reinstalled generic drivers, audio works and Lync is not hogging 15%+ of the CPU constantly.

The Dell IDT driver turned out to cause this same problem for me. However, I'm still able to use the audio device with the Windows 8.1 integrated drivers and use a mic/headset combination device using the 3.5mm connector.
