Mainline - buzz on left channel

[hpleung]

Hi,

I completed the mainline and now doing hearing test. I am hearing 2 things:

1. A form of static sound that comes and goes - its not always there.
2. It feels the sound becomes more "open" and less "open". Hard to describe.

The right channel seems to be ok - I can't tell for sure.

Based on this - my best guess is that it is a wiring solder issue.

Are there any guidance on where to look?

Thanks.

I would reflow all of your solder joints.  Bad sound that's hard to pin down is often a cold joint making its presence known.
