On my Windows 7 laptop, when I plug in my EXTERNAL speakers, the volume is OK, also when I Skype using my INTERNAL speaker, again the volume is quite adequate with my mp3 and audio files. BUT --- when I try to listen to my mp3 and audio files with the INTERNAL speaker, I can hardly hear anything, very weak volume. The volume bars are all on maximum, so what can I do? Strange that when I Skype using INTERNAL speaker, all is OK!
i'd be looking at audio manager on your computer.i have realtek hd audio manager on mine you'd have something similar on yours,it might have sepaerate settings for mp3s and audio files.also the player your using to play mp3s and audio files might have its own volume controls.
f so, you have a warranty or "fitness for purpose" issue. What sound card or built in device are you using?
