Why does Windows audio stutter?

Because the CPU or driver stack can’t feed the audio buffer on time.

Do wireless headsets make it worse?

Sometimes - test with wired to isolate.

Will lowering sample rate help?

Yes - it reduces buffer size stress.

Do browsers affect audio quality?

They can when using WebRTC - keep only needed tabs open.

Does Game Mode help audio?

It can reduce background interference slightly.

Can PC-Care.ai help automatically?

Yes - it trims startups and background tasks so audio threads have more CPU time.

Stuttering Audio Windows on Lenovo ThinkPad - causes, fixes, and prevention

Written by PC-Care.ai Editorial Team - Content Lead - Reviewed by PC-Care.ai Engineering - Windows Optimization - Last updated 9/14/2025

Overview - what this guide covers

This guide explains how to measure latency, update drivers, and reduce background load using PC-Care.ai so audio stays smooth.

Symptoms you might see

Crackles during Teams calls
Audio cuts out on Bluetooth
Delay between video and sound
Fan spins up during playback

Crackles mean the audio buffer underflows due to CPU latency. Bluetooth drops happen when bandwidth or driver stability falters. Video-audio delay indicates high processing load. Fan spin-ups show CPU spikes under the hood.

Manual fixes - step by step

Update audio and chipset drivers
Disable unused audio devices in Sound settings
Set audio to default 16bit 44kHz
Use wired headset to test
Trim startups with PC-Care.ai
Disable power-hungry background apps

Updated drivers reduce latency. Disabling unused devices removes driver conflicts. Lower sample rates stabilize buffers. Wired headsets eliminate wireless issues. Startup trimming keeps CPU available for audio.

Prevention - keep the issue from coming back

Check DPC latency with tools like LatencyMon

Keep audio drivers updated monthly

How PC-Care.ai helps

PC-Care.ai detects and disables tasks with high DPC latency so your audio pipeline stays smooth.

With less background load and fresh drivers, audio stutters disappear.
