Comment 13 for bug 1440675

"It is not the responsibility of Mixxx to make up for a poor user experience in the OS. The real bug is lack of good graphical sound setup utilities in the distribution. Just having a button that opens alsamixer doesn't really solve the problem if people don't know they have to click it. And if they know they have to use it, they can just run the program. The stumbling block is not an issue with users having difficulty running the program."

It is the responsibility of Mixxx to educate users how to get the best sound out of Mixxx and make it easy and intuitive to do so. Just having a button to open alsamixer doesn't solve the problem, but redesigning the GUI and editing the manual to lead them towards adjusting their hardware controls would help more. See bug 1458677. For GNU/Linux users, where there is a (nearly) ubiquitous way for Mixxx to show the hardware controls (opening alsamixer), this button would make it even easier for users to do so.
