I have just finished my portable and whenever I plug in headphones using the switching headphone jack, they heat up. Within a minute they are irritably warm, so I have to take them out of my ears.

I tried researching this problem and it seems to be “high dc offset”. I measured 2.46v from the left and right channels to ground which is exceedingly high. Any recommendations of what I should do?:\

I am using the PAM8403 audio amp.

The PAM8403 is not intended for use as a headphone amp, it's a small speaker amp. A capacitor in series with the audio line can eliminate DC bais. AC passes through capacitors, but DC doesn't.

Thank you so much. What type of capacitor, electrolytic? What rating should I get also?
