My K3 behaves just as you describe.

With spkr+ph set to yes, and spkrs to 1, sound comes out of the 
left headphone only.

I would plug your computer speakers into LIN OUT, not speaker 
out, and leave spkr+ph set to NO. The K3's speaker amp is 
fragile, and can be blown with a loud signal, especially with AGC 
OFF.
