What Causes Audiodg.exe High CPU Usage?

Sometimes, audiodg.exe may seem to use a lot of CPU resources. There are a number of reasons for this. Below are the common culprits associated with the high CPU consumption of Windows Device Graph Isolation:

1. Audio enhancements/ effects.

Audio enhancements cause high CPU usage while playing audio files in Windows Media Player. This problem is also reported in other media players like VLC. Audio enhancements work by processing audio files as they play, thus leading to a sizeable rise in the utilization of the CPU.

2. Volume adjustment.

The volume adjustment causes audio processors to be optimized for specific sound cards and drivers, which means any other software can also access these options. Volume adjustment allows an application to apply effects directly to the audio stream without re-encoding the entire file. This has been associated with increased CPU utilization.

3. High audio sample rate

In a 44 kHz recording, there are 44,000 samples taken every second. If that recording is increased to 88 kHz, there are 88,000 samples per second.

An increase in the frequency of audio sampling increases the dynamic range of the audio file and the CPU resource allocation.

4. Outdated or incorrect audio drivers

If you hear crackling sounds or distorted audio, it is caused by an outdated driver. Your computer's sound card requires a compatible audio driver to output Sound. Older versions of Windows may not support the latest audio drivers, and new ones might not be installed when you update your operating system.

Computers with outdated or incompatible audio drivers are more than likely to experience increased CPU usage due to this system file.
