Drivetrain noise driving me bananas!
So, here's the story.
I bought my 2010 Surly Steamroller new in April. About a month ago, I noticed some resistance and it was getting harder and harder to pedal. I took it to the LBS and they said the rear wheel bearings needed repacking. Ok, fine. It was seemingly fixed then. Recently, I switched to a smaller toothed cog. Sometime after this happened, I started being able to hear the chain as it spun around. This was weird to me since before it had been dead silent. I took it back to the LBS and they said I need a new chain. Ok, I had only put about 2,000 miles on, but whatever, I need a new chain. I bought the SRAM PC 870. The new chain did not fix the noise. It did not fix the slight vibration I can feel through the pedals either.
The chain sounds like this without the pinging. The bike in the video is not mine:

I've taken the bike to four different shops and they all tell me nothing is wrong with the bike. I can feel it though! I feel like it's slowing me down!
One shop said the chainline is not completely straight. It's just so very slightly off. Should I get a new chainring?
I've tried having the chain both really tight and really loose and the noise is still there.
The chain and chainring are both 3/32" I think. Do you think the cog is 1/8"? Would that cause the problem? I don't have the tools to remove it or else I'd look.
I feel like the bike shouldn't have these problems after half a year of use!

If the cog was 1/8", the chain would not go around it without a lot of effort, and (hopefully) the shops would have noticed that immediately.

Maybe the cog is bad...I don't like the shop that installed it anyway. They didn't give me my old cog back and I left the store forgetting about it. I had to go back the next day to get it. They weren't gonna give it back.
What would be more likely to be bad, the cog or the chainring?
