I continually notice the volume balance (L-R) on my mac ibookG4 keeps changing itself. I have been working on disabling the remote access to my machine, but have been unable access the sudoers. What do you suggest? Is a malicious program or a person changing the settings? How do I prevent this from occurring in the future? :confused: Thanks in advance for your help.

What OS are you running? This was a known issue in previous versions of OS X (like 10.2, 10.3 and 10.4)

Yeah, it's a bug in pre-Leopard (pre 10.5) Apple OS' (which I thought they fixed in the latest releases 10.4.x).

That problem used to drive me nuts. It's apparently caused by changing the volume when CPU usage is high.

I'm having this problem on my iMac running 10.8.2. Constantly having to go into system prefs and adjusting the balance back to the middle.

I am also having this problem (running 10.8.3) and have yet to identify a cause or any kind of similarity between occurrences.

It is very annoying and would love to have it fixed.

UPDATE: I can confirm that one application (PlayerPRO) reproduces this every time if it crashes on launch. This is caused by the way it uses OS X's audio system - it tries to restore the state of its mixer, and as part of this process, initializes the mixer (which sets the balance to 100% right). Then, before it sets all the parameters, it crashes, leaving the balance 100% right. Annoying.

That being the case, are any of you using OS X applications that do audio heavy lifting? These include applications that have advanced audio composition (Logic Pro X etc., audio redirection apps (Airfoil etc.), and audio capture (Soundflower and all apps that use it, Audio Hijack, etc.). These apps can sometimes do goofy things with OS X's audio system, especially if they run at startup. Try disabling their startup behavior and see if that helps.

2018 macOS high Sierra 10.13.5 running on mid-2014 rMacBook Pro 15 and still have the same problem of sound balance changing itself.

No special software installed, only third party software I could see interfere is VLC 3.0.3

I always keep my system clean and optimized, as of this post Avira and Malwarebytes have been installed and keep an additional eye on security.

This has been also happening on the last version of macOS Sierra

Not a good feeling...

Hey what's up Craig Federighi! How was golf last week?!
