When you inject audio in C63 with PTT pressed, does it transmit ?

My uBitx V6 has the problem from day 1.
After initial BFO calibration, it receives well.
Transmits only career and no voice when I press PTT button.
CW mode does go well.
Changed the PTT mic and issue remains same.
6.9 Volts bias measured across mic.
Injecting voice from external signal at C63 plays in speaker well.
Q6 biasing voltage looks to be normal. But I have suspect on this.
Any one solved such problems in the past and can offer help please ?
