[Elecraft] [K2] No int. spkr audio

[Petr Ourednik]

Hello

Sorry for bothering with maybe stupid task...

My daddy called me this morning that he has no audio on his K2 from
internal speaker. When he plug in the phones it works. (Yda evening int.
spkr worked too) 

Is it the problem of switching contact inside of the Phones socket on
the front panel or it can be issue somewhere else please?

I have no K2 on the table and I did not found so much in the manual...:(

Thank You for hints.
