Windows 10: Audio Enhancements artefacts break Teams calls.

The default enabled "audio enhancements" in Windows break the codec used in Teams calls, they result in fragmented sound and the initial part of speech following even an instant's silence being replaced with an impulse. I could render how this sounds this in text like "I an ot derstand at ou re ying". At first I thought the issue is packet loss, but Teams was reporting no loss. The only hint I got was that playing another sound in the background changed the behaviour. I played a music track at low volume, the behaviour changes. When the host is not speaking, the music is louder, but has clear

Audio Enhancements

Hi Charlotte,

One step that we could try is to manually re-install the Audio Enhancement, and see if it helps. First, go to HP's website and download the latest Audio Enhancement installer (IDT) and save it to your Downloads folder. Once done, follow the remaining steps
below:

• Search for Control Panel via Cortana search and hit the
  Enter key.
• Open the Device Manager and click Sound, Video and Game controllers.
• Right click the IDT device and select Uninstall.
• Restart your PC.
• Once your PC restarts, it should automatically load all audio driver. Let it complete the process.
• Go to the Downloads folder, right click on the IDT installer and select
  Run as administrator.

Once complete, check if you have the enhancements back and let us know the outcome.

 

Microsoft Teams Audio faint for multiple users

We've had a number of users who recently received new devices complain of faint microphone output.

Devices affected

• 3 x New Surface Pro 7
• 2 x New Surface Pro Book 3

I'll add steps we've taken to test the device at the bottom.

So far, we believe it may be user-specific as we have been unable to replicate the issue using a local admin account.

These devices were provisioned ~1 week ago. Users raised the issue shortly after they were delivered.

There is nothing physically wrong with the devices. No bangs, scuffs, cracks, screen protectors, etc.

Steps taken so far:

On end-user profile

• Current call is done via Teams and mic audio is definitely quite low
• Checked Mic settings and are already all at max
• No Booster available for Mic
• No additional settings in Teams to enhance mic audio
• Ran Windows Updates and no updates found
• Checked Device Manager and is up to date there as well
• Computer was just rebooted not too long ago too

• Checked Recording sound options
  
• Reset sound options to default
• Troubleshoot Realtek microphone - didnt pick up anything
• uninstalled microphone realtek audio drivers
• restarted computer - tested on Teams - still very faint

On Local Admin profile

• Tested mic via camera app and teams call - Could not replicate the issue.

Please let me know if there's any additional information that would help find a solution.

 

Audio Enhancement Disabed but wont play audio or video

All the steps have been tried. I have been dealing with this issue since last week so many of the steps you suggested or sent had been tried already and a few more than once. The PC has been through a soft reset, a factory reset, and I also did your suggestion of the repair reset.

I am still getting the same issue. When the audio enhancement is not on the audio does not play, the test tone audio fails, no local video files can play either. No YouTube videos or any online video plays. Youtube screen will say an audio rendering issue. Local audio files will give error and say it is unsupported coding...0X8000FFFF, when the enhancement is on there is no issue at all

Drivers, Bios, chips etc are up to date. I have had this laptop for less than 2 months, so I did not really have any 3rd party software installed.

Troubleshooter even suggest disabling the enhancement but again...this is the problem.
