    I just moved and put together my surround sound system. I'm running 7.1 through a Sony STR-DH770 (1000 watt 4K 7.2 receiver). Everything works beautifully and sounds great except my subwoofer.

    I have an Hsu Research STF-2 (10 inch 200 watt) that doesn't want to work unless I'm running a subwoofer test. For instance. If I watch a movie I get nothing, if I listen to music via bluetooth off of my phone, nothing, cable gets nothing. However if I go to YouTube and play any random subwoofer test, it works. Some things to note. The sub as an Off/Auto-On/On switch doesn't change whether it works though. It has a Crossover Out/In, doesn't change anything. Crossover Frequency doesn't change anything as far as it working and neither does the phase being at 0 or 180.

    One other thing to note, it seems to work when I run the auto calibration, but it is very weak. Not sure if that helps, but that has been one other thing that I've noticed. This is also a powered sub so it's not an issue with not having enough power going to it. Any help would be greatly appreciated!

    Check the receiver speaker setup settings. Be sure you have ALL speakers set to small/using a crossover no lower than 80hz.

    Also, be sure you aren't using a listening mode that bypasses the above bass management settings and is, effectively, a "pure" 2.0 style..:)
