Bass module 700 pop sound when turned off
So I have a soundbar 700 and the bass module 700 linked together wirelessly. It sounded great till I had some popping sounds during movies due to wireless interference. I got a 3.5mm Jack and wired the soundbar and bass module together and It got rid of the popping sound.
Now i have another issue. When my system goes on standby, my bass module makes a popping sound after 2 seconds. I understand it has something to do with the wiring cause having this setup wirelessly never had this issue.
Is this normal? Is this consider as safe for the subwoofer to make that popping sound everytime I turn it off? I see the speaker move when making this sound.
