Well in instr 1 you´re multiplying two enveloped oscillators of maximum
ampliture = 10000 each, so you´ll get a peak amplitude of 1000000, far
beyond the limit of about 32000 for a 16 bit output. You´ll only hear a
click at the beginning and at the end of the note because all the signal is
clipped.
In instr 2 you perform an addition, so the output amplitude can go up to
20000 which is ok for 16bit files.
If you want to hear how ring modulation sounds (instr 1) I suggest you to
use normalized amplitudes (p4 = 1 in the score) and multiply the result by
10000 or whatever you want.
outs 10000*asig1*asig3, 10000*(asig2*asig3)
With normalized amplitudes you won´t have to be bothered by overflow.

Hope this helps,
