Sony released an update for PS5 accessories without prior announcements. The company did not publish a changelog, and soon after installation, users began reporting widespread failures.
Pulse Elite unexpectedly disconnects from the console, sound disappears in games, and it's impossible to re-establish a stable connection. The cause was a synchronization failure between the headphones and the PS Link adapter connected via USB.
The community has found a temporary solution to the problem. You need to connect Pulse Elite to the console with a USB-C cable, open accessory settings, go to the general section, and select PlayStation Link device support. After that, you need to manually start the adapter firmware update – this resolves the conflict and restores the connection.
