It’s all a bit Heath Robinson, but it works.
I have my Netbook perched on my ukulele case and plugged into a cheap USB powered speaker. I bought the speaker at PC World on special offer for three UK pounds (!) before I left. It really is quite good, clear and very loud for a cheap Chinese no-name product sold under PC World/Curry’s Logik brand.
The whole set up also looks kind of cool propped up on the antiquey brass bed draped in a mosquito net. I imagine that this is how Ernest Hemingway would have watched movies if he was a nerd.
