nothing it apears on my startup but cannot find it in pc anywhere
it is a sound manager of some kind.. you can set up volumes and such
It comes with c-media sound devices as far as im aware
it keeps taking up about half of my cpu making my computer slow, when i end the task explorer crashes and i have to reboot
One copy under c:\winnt runs automatically and triggers my attention. This mixer.exe has 1776 KB while my computer search comes up with 3 other mixer.exe all with 1544 KB. I don't know what it does but seems very strange indeed.
C-Media sound properties - hangs sometimes win XP if left after change to another sound hardware
When this app is running for long periods of time it seems to sap resources heavily (memory leak?)
Substitute audio mixer for Windows volume control. Extremely annoying self-loading prog that is in fact quite useless. Installed itself against my wishes when installing a new sound card. I'm here looking for a way to get rid of it once and for all!! I've rated it as dangerous because of its invasive and pervasive behaviour.
It was taking up over 200k kb of memory, so I just right-clicked -- end process, and it ended without anything bad happening. So I just assumed it was malware or a trojan or something.
Popped up a week later after I put in a new sound card. doesn't seem to be doing anything yet. Sneaky little thing though... is not revealed when I run a search for it . Says it found 1 file , but doesn't show it. Has staged itself in the Startup rooster. Ironically, I was already having trouble with the sound drivers ... no sound for it to mix...
Belongs with C-media soundchip driver package
Mixer.exe is taking up 1 gig of my memory and i cant delete it. I'm not even using the onboard sound card anymore so I don't need it at all.

It is a C media file, I believe for your sound to work, you have to leave it running in the background. But run a scan just to check.

As my PC run 5 days mixer.exe used over 750 Mbyte of Ram. This tool is realy buggy

Mixer.exe is a royal P.O.S. and has a memory leak when it has been running for over a certain amount of time. Thus I know bc it should use about 5 mb of memory but instead the other day it was using around 267mb! lol I would just delete the file and revert back to the basic windows mixer. Much more stable.
  Gosh darn I hate Mixer.exe  
I had a mixer.exe that was using 400MB of RAM. It was in a non-existent directory off my desktop. Yah - I been pwnzed.
I was using 2.0gb of ram! When i ended the procces my ram Usage came down from 2.55gb to 259mb. Its not dangerous but It Hogs up the RAM!

rc in task manager and ended process and nothing bad happened, sound still works and now i have 1.6 Gig of memory back to use elsewhere now lol
You think 1GB is much? try having it use 2,3GB....And I don't even have a C-Media soundcard on my MOBO (780I FTW)
it showed up with my old c-media sound card which i long longer use and i cant get rid of it its in add/remove programs but cant be removed im totally lost as to getting it off my pc i may try putting the old sound card in to remove it (if i can find it...) it starts every time i restart and it runs for hardware thats no longer in my desktop
Finally was able to get rid of it thanks to the post at the top of this page. I was about to search my registry, and googled mixer.exe. I found this page, went to the registry key mentioned, and there it was. I deleted it and got a warning from ZoneAlarm telling me that the registry was trying to prevent subsequent calls for this "dangerous" P.O.S. I just hope no app needs it. I'll find out soon.
has memory leak, disable startup with msconfig - use standard audio mixer
i have found mixer on my pc many times and have tried to end it, but it shows up running again months later. I know that it coincides with muting my microphone, deep in the audio software. coincidently, i havent been able to chat on yahoo chat since it showed up a week ago. I have since stopped it under msconfig.exe startup and now i can chat on my mic again.
C-media mixer comes with an uninstaller named "CMUninst". The default location is C:\Windows\Program Files\C-Media\Win_ME\CMUninst. Run the uninstaller. Reboot. Gone.
i did some searching and found it to be the volume control for your computer. i now have a different sound card however if you go to startmenu, all programs,accessories,entertainment, volume control, there it is. i went to my computer and searched for c:\windows\mixer.exec and found the file. when you click on the file the volume control pops up on your desktop

Best practices for resolving Mixer issues

A clean and tidy computer is the key requirement for avoiding problems with Mixer. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
