You can use one TDA2822M IC and connect it bridged to one speaker for an output of 1.1W.
Then you can use a multi-pole switch to change it to stereo for headphones.
It is easier to use a second TDA2822M and use one channel for one channel for headphones and an output coupling capacitor on the output of the bridged TDA2822M for the other channel for headphones.

If i have the circuit setup for the one Speaker which can only be mono with one speaker. correct!
Now...How do I use the multi-pole switch, and a Headphone switch jack to made the headphnoes in stereo. Please advise.
How do i setup set for two tda2822 chip as stated in the last paragraph. Don't understand.
I'm choosing on which way i want to use either the one chip or two. So i need help with both.
