Some issue with wireless headphones can sometimes cause Lost Ark to output no audio even after restarting the game. This is supposedly caused by the game not using the correct output device. The issue was solved after rebooting my PC.
When using “Spatial sound” with headphones (I was using DTS:X) or another 7.1 surround sound system, the game only outputs to the rear channels which results in the game sounding very thin.
I ran into these issues after setting up a new wireless headset (HyperX Cloud Alpha Wireless) , and enabling “Spatial Sound - DTS:X” while the game was running (this option is available on Windows 10 when right-clicking the volume icon). It caused the game to immediately go silent even though my PC output was set to the headphones. Restarting the game multiple times did not fix the issue. After I restarted my PC I was able to hear the game. If the game had an audio output setting it might alleviate this rare issue and possibly solve some other sound issues.
This then revealed the other issue of the surround sound implementation. It sounds like everything is behind you. I think surround sound for an ARPG is not really necessary but it would be cool if it worked as intended or at least was output to the front/rear channels more evenly so I don’t have to enable/disable Spatial Sound when I go to play Lost Ark.
As a final note although surround sound might seem unnecessary for an ARPG it would be cool for finding guardians or as another way to orient yourself in a raid (I play Sharpshooter so I’m always 10 miles away from the boss).
These bugs have apparently been in the game since launch. They have been discussed before in these threads:
