I'm afraid something might be gone wrong with my buzz fix. Had a look at
it yesterday evening and noticed one of the soldering points is really
weak. Maybe that could be a reason? Too little of a connection from the
capacitor to the resistor?

Tried it. Still so soft that you have to yell really loud at the phone
and only hardly can hear anything on the other end. I'm usually testing
with my stereo, turning it on and putting the phone on the speaker. But
I have to turn my stereo to levels it's getting uncomfortably loud just
to hear a faint noise over the phone.

Fresh out of ideas
