I have a Sony HT-CT380 Sound bar that came it's own wireless subwoofer.  Sadly the subwoofer has now packed in.  Can I use another subwoofer with this sound bar ?  If so how would I connect it as I can only see HDMI and an optical connection on the sound bar.  There is an analogue in port as well but not sure how I could connect that to another subwoofer.
Thanks.
