[ubuntu-uk] USB sound device for recording line-in to a laptop?

[Adam Funk]

Would anyone like to recommend an external USB sound-device with a
line-in input, suitable for recording from a hi-fi line-level
connection using Audacity?  I have no idea what to search for or what
the price ranges are like.

A 3.5 mm or 2.5 mm stereo jack would be fine, or even a pair of RCA
jacks.  This is for a laptop running Ubuntu that has a mono microphone
jack but no line-in.

Thanks,
Adam
