I have noisey speaker (buzzing and crackling) also when on loudspeaker, however I dont get it through headset. The other problem is although headset attached I still get ringing through phone speaker (buzzing and crackling included) but at the same time though headset crystal clear.
I have put link wire to powerswitch as pad had gone BUT this problem was already evident before I did this. I'm assuming its feedback problem and not ic as sound is good through headset.
Any other suggestions besides whats already here?
