After the update, the Talent 2 on the Rapid Transit route has lost almost all of its sound. I checked the Talent 2 on Köln-Aachen and it's not my sound system. The "improved" sound on RT is almost non-existent. There's dead silence in there, only the switches can be heard. No running noise, no wind, no fan sound (which is probably the most dominant sound on Köln-Aachen), nothing. The exterior sound is fine, but since the windows can't be opened on the Talent 2 almost nothing can be heard inside. Just compare it to the Talent 2 on Köln-Aachen to hear the difference. I hope it's just a bug you can fix and not a deliberate sound mix.
