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.
