OC/DC - All the right notes in exactly the right places.
If the OPs stuff is where is should be, averaging -18dBFS then yes, the HP output is going to be pretty wee but rather than boost that I would strongly suggest, as I am sure will others soon, that he buys a USB interface with a balanced line output.
Even a fairly cheap £100 AI will deliver around +10dBu for 0dBFS, not "pro" levels but should easily drive any mixer's line input. The sound quality will also likely be vastly better.
I saw a S/H Native Instruments KA6 in my local Cash Generators a couple of months ago for £100. JUST the jolly job!

Most mixers are full of 'gain boosters'... that's kind of the point, really... so I think to offer sensible advice we need to know more about how you are connecting the laptop to the mixer and what the mixer is.
I presume you have already experimented with the laptop's volume control?
...And is the sound just quiet, or is it missing the central-panned sources like vocals and bass?
While waiting for those responses, I can say there are several potential options.
1. Connect to a channel line input (or two for stereo) and increase the channel gain.
2. Invest in a suitable DI box (several are purpose-made for laptop connections) and connect via a mic channel (or two for stereo) -- there'll be plenty of gain on hand then!
3. Invest in a simple USB interface and connect via a line channel (or two) again.

as you're probably feeding L+R into a balanced input. Anything that's on both sides will be cancelling out.Hugh Robjohns wrote:missing the central-panned sources like vocals and bass?
Try a cable like this:

into 2 channels.
