[linux-audio-user] hum from laptop soundcard

[juto aviten]

Dear friends ,
i have also problem with hum when i used sound with my laptop, it's the 
plug, when i used only battery, it's perfect... but when i put directly 
electricity... it's finish, i have a big hum and it's terrible when you 
make sound or playing live... but i think it's an hardware problem not 
software. But is someone find a solution (without the fact to buy an 
external card) as for example find another AC adaptater...??? Mylaptop 
is Gericom and i use Mandrake 9.0... if you've got an idea, your just 
welcoming... and thanks you.


best
