Harman Kardon AVR335 mute question help

Hi, I have Harman Kardon AVR335 with faulty logic board and I want to use the output stage only. I don't need any mute functionality so I will remove the mute input transistor marked with red dot on the attached schematic. But not sure what to do with the P_mute marked with green. To connect to ground or to feed with any voltage or what? Any help is welcome. Thank you very much!
