MaxxAudioPro high CPU usage (with and without audio playing) due to missing registry keys?
My laptop is Dell 5577. It came with MaxxAudioPro audio management suite which isn't written correctly. It causes high (3-5%) CPU usage while listening any audio. It isn't supposed to use any CPU. Disabling special effects doesn't help.
I used Sysinternals tool and found out that it's trying to access registry keys (Stream1, Stream2 etc) that don't exist. It keeps looking for these keys hundreds of times per second, so my guess is that's why it causes high CPU usage. While there is no audio playing, WaveSvc.exe still uses 0.5% CPU; it isn't supposed to.
I partially solved the problem after disabling Wave Audio Services service from Windows Services so it won't start after a reboot, then disabling Waves MaxxAudio service from Task Manager > Startup tab. After a reboot there is no trace of WavesMaxx software running.
The problem I'm facing now is that when I remove earphones, the YouTube video pauses because the PC tries to switch the playback to speakers. I have to click the YouTube video and rewind it to resume the playback, this time with speakers. If I plug the earphones back, the speakers continue to play audio unless I rewind the video. To play a local audio file from earphones again, I have to go to Windows 10 "Playckback devices" and disable speakers.
Please fix the drivers, Dell! This is a brand new laptop and I'd hate to return it for a problem like this. It is a major inconvenience. Thanks!

Uninstall the OEM audio driver and restart.
Then manually install the OEM driver and restart.
Maxx Audio is not native to windows and Feature updates break it.
There is no one size fits all driver for every dell on earth.
Depends on specific model as to which driver is the correct driver.

We have the same issue on a number of different models.
Worst affected are the Dell latitude 7490 and 7390 when using the WD15 dock.
We see explorer sitting at about 10-12% cpu when not docked but once docked we get CPU rising to >25% and reports of RTKAudio and MaxxAudio issues in eventvwr and other monitoring tools. I've made sure all the drivers are up to date and that the WD15 dock has all the latest updates (3 different updates available from Dell) but we can still replicate the issue across multiple machines.
Anything else anyone can suggest I try? Its new financial year now and I'm starting to consider switching suppliers to see if this is endemic to Dell or a wider Win10 issue.
