When I'm using an earphone for my laptop, the sound is unbearably loud than when I'm using speaker.
In Control Panel -> Sound, it seems that both of the laptop-embedded speaker and earphone are controlled by 'Speakers/Headphones' device. Thus I cannot adjust the volume separately. If I don't want to buy another device, is there any way I can adjust them using software or within from Windows 7?
My laptop is Dell New Inspiron 14z, and 'IDT High Definition Audio CODEC' is used both for 'Speakers/Headphones' and 'Communications Headphones'.
