I just got an arc and a sub and upgraded my system to S2. The Arc works great, but I don’t get any sound from the Sub. I have tried to disconnect it and connect it again (even did a factory reset) but no change. The sub is visible on my network and everything looks correct in the software, it is just that the Sub does not give any sound. The Arc however changes a lot when the sub is connected, it is like it opens up a lot more sound on the upper frequencies, but without the Sub too much of the lower spectrum is missing.
Any idea? Did I get a broken Sub?
