Drive belts and power steering pump

I have a 2001 Outback sedan (4cyl, auto) with 103K on it. I just had the drive and timing belts replaced according to Subaru's recommendation. Now my power steering pump makes a fair amount of noise when I'm driving, which I have never experienced before. In fact others noticed it right away too. I've had a pump go out in another car and the noise sounds the same.

Could this somehow be a result of having the belts replaced? It seems too coincidental to me.

note: with the timing belt I did have the tensioners, water pump, and thermostat replaced as well
