But, then I started to notice the sub problem. If I'm being honest, I didn't realize this whole time that the bass of the subwoofer was cutting in and out. I'm not sure exactly when I started to notice it, but once I did, I couldn't stop hearing it. It happens so frequently and intermittently that it's hard to tell at first I guess. But that's the biggest issue and once you notice it, it becomes extremely annoying. Over the last year or so I've half-heartedly attempted to look up the problem. It's taken this long for me to actually do something about it because I often use headphones instead. Looking it up, there's a few discussions specifically about the Signa S2 and subwoofer cutting in and out. I'll save you the trouble of having to look too far. They usually say it has something to do with wireless interference. I can tell you as of today that's definitely not the case for me. Admittedly, I have multiple network devices (Modem/Router combo AND a secondary Router). Both devices have wireless with both 2.4Ghz and 5Ghz bands. But I have the wireless disabled on both of those devices. My PC has onboard wireless with again the same bands. Everyone says it's the 5Ghz band and that by disabling it, it fixes the problem.
First, no one should have to do that. I have my sub RIGHT next to the soundbar. There's nothing between them. But regardless of all that, today I disabled everything. There was no wireless signal from any device in or around my PC (including Bluetooth). The subwoofer was still cutting in and out.
I tried multiple times using the sync button and forcibly reconnecting the subwoofer to the soundbar using their pairing method over the years. Nothing fixes this subtle cutting in and out.
So I'm done. As of today, I'm moving on. I'm in the middle of narrowing down on a couple of integrated bass soundbars to avoid any possibility of other wireless devices somehow interfering with my audio device. To be perfectly honest, in this day and age, that just shouldn't be happening anymore. It's a reminder of the old days of 2.4Ghz wireless house phones interfering with wireless routers causing disconnects on your gaming sessions. It's just makes me wonder what were they thinking? Hopefully this helps anyone else thinking about trying the same thing to avoid the same mistake I made.
