Sneaky DS - analogue output very low after move

Hi all,
I have just moved to a new home, meaning the system is now hooked up to new network. Now the analogue output is VERY low. If I turn up the volume on my pre-amp to 100% I can barely hear the music the Sneaky provides. The Ethernet LED is flashing, indicating it receives a constant flow of data.

I ran Konfig and it claims everything's alright.

I fear that something inside the Sneaky broke while transportation. Nevertheless I wanted to explore the probability of a different issue I might be able to fix myself.

Any ideas?
