If XMPlay seems slow, responding with a delay to volume or track changes
You may face this problem with XMPlay, when you increase or decrease volume, change track, even start or stop playing a track, XMPlay responds several seconds after you send the command using a hotkey or pressing the relevant buttons with the mouse.
Unfortunately the web site of XMPlay is not very helpful, but the problem can be easily solved. It occurs only when you have increased the buffer size.
Go to Options > Output, and at the “Buffer” section drag the slider to the end of the left direction (0.100s).
Enjoy the new speed of your player!
