XPS 13 (9343, Early 2015) Waves Maxxaudio CPU use

I'm having the exact same problem on my XPS 13 (9343).  I uninstalled and reinstalled the audio driver but the problem persists.

There is another process that seems to run at 30% CPU usage as well but I don't remember the name.

I'm going to see if I can reproduce the problem by logging in more than 1 user.

The other process is probably the igfxEM process related to the graphics driver. The supplied Dell drivers are extremely buggy. You can solve this by updating the Intel driver (https://communities.intel.com/thread/57299).

Quite logical the XPS 13 won't even last 3 hours on a battery charge when 2 processes are constantly using 60% of the CPU.

Thanks! The igfxEM process was the process that I couldn't remember.

Regarding the sound driver, it was surprisingly easy to reproduce, unless I got lucky. I just simply logged into a second user, started a browser, then played a video on youtube.  After I closed the browser, the audio process remained running at ~30%.

Just upgraded to Windows 10 and installed the Windows 10 sound driver. Still the same issue! The battery drains in under 2 hours with multiple users logged in......

Same here. I upgraded to Windows 10...same problem exists.

I just ran into this today on a new XPS 13. Waves MaxxAudio is hovering around 9.4% CPU usage all the time. What's up with that? How do we either get rid of it or kill it's CPU usage?

Any answer from Dell?

Same issue here as well. It's surprising that Dell hasn't fixed or even acknowledged this yet, as it's a pretty major issue!

Anyone have any updates to this, after 3 months?

I've determined that the WavesSvc64.exe process is repeatedly querying a few registry keys that don't exist (See http://1drv.ms/1OgQPWG ).

HKLM\SOFTWARE\Waves Audio\MaxxAudio\General\Param308
HKLM\SOFTWARE\Waves Audio\MaxxVoice\General\Param1095
HKLM\SOFTWARE\Waves Audio\MaxxVoice\General\Param1126
HKLM\SOFTWARE\Waves Audio\MaxxVoice\General\Param1128

I've tried manually creating the keys with blank values but hasn't solved the issue. Really frustrating.

Easily reproducible as mentioned by others by logging into a second user and playing audio.

Any information would be appreciated.

Same problem here. Any solutions to this problem jet?

Still hammering the CPU and killing the battery on Windows 10 v1511 running the latest Realtek drivers (v6.4.10041.127).

Does Dell even care about their customers?

I still have this problem too, though I rarely have multiple users logged in so can make do - it's unacceptable that nothing has been done though.  Is there a more effective way to get Dell's developers to look at a problem like this?  E.g. by phoning Support or tweeting them, seeing as Twitter's more of a public forum?

Failing a software solution, I'd be happy to accept a hardware one in the form of an upgrade to the XPS 13 9350... Your choice, Dell :-p

I am getting ~30% CPU use of this process as well, also on my Dell XPS 13 9343. This happens also when there is just one user logged in. Please fix this Dell!

Also experiencing this error.  +30% CPU being constantly used by the Waves MaxxAudio Service Application, causing the battery life to reduce to less than 3 hours on a new XPS 13 9343.
