With the input at 1.4V peak and a gain of 8 times then the output will have a peak of 1.4V x 8= 11.2V that needs a supply of more than 11.2V x 2= 22.4V, not 12V.

Increase the value of R1 to reduce the gain (or reduce the input signal level) and reduce the value of R6 (for symmetrical clipping) until the clipping does not happen.
I have R1 at 4.7k and R6 at 5.2K.
