Can anyone see any reason i why i can't control the +ve for the speaker with a pnp transistor attached to either pin 34 or pin 16 (most likely to use pin 16 i'd reckon).

Switched low keeps speaker turned off til the drive/motor is in use and as a result stops any rouge signals that aren't meant for that drive.

It works in testing, so just want to make sure i've not missed anything obvious that'll cause issues.
