The speaker hum/static sound came back today
and this time I tried the diagnostics. I unplugged
the speakers and tried each one in the diagnostics
port for low and high frequencies and both played
although they sounded the same to me. So according
to the test the speakers are working normally.
Afterwards the humming stopped.

Humming PC speakers are usually caused by a bad connection on the
plug. I use corrosion block on them.
