Hi,

i want to be able to play my laptop through the stereo at home without losing volume and getting average sound quality when i turn it up loud.  Is there any reasonably priced portable device that i could plug into my laptop which amplifies the sound which can inturn be plugged into my home stereo.

Thanks heaps!

Some questions...

1:  What make and model is the laptop?
2:  What sound card/chip does it have? 
3:  Does the laptop have line out in addition to speaker/headphone out?
4:  Have you tried increasing the volume in your OS volume controls rather than with the volume knob on the laptop case?

Potentially a USB sound card would be a good option for you.

It's an HP. I'll check and get back tomorrow.

Cool

USB soundcard, the output on a laptop is a headphone, and thats always problematic feeding into a line in. Despite the easy availability of 3.5mm to rca cables, you really need something to bring the level up to line levels from the lower voltages that a headphone out has, or a proper line output like a USB soundcard has.

One HP I used recently had jack detection, but it was no different when choosing line out or headphones, they both were the same levels and impedance. I really think that the options in jack detection are a bit of a croc anyway.
