Output Pairs empty - Master/Cue "No enabled stereo output"

Hello, I have the same license and AUTO/PILOT 0.1.846 on two Windows 11 machines, and audio output behaves differently on each. On Desktop: Output Pairs are listed, Master/Cue can be assigned, and playback works. On Laptop: Output Pairs is always empty, Master/Cue show "No enabled stereo output", and decks are silent. Only the Test button produces sound. Same result on every output device (headphones, speakers, HDMI monitor) and with DirectSound, Windows Audio (Exclusive), and ASIO (FlexASIO). The same headphones work fine on the desktop version. Windows Audio (shared) fails with "Couldn't open the output device!". After a restart, the app falls automatically back to Windows Audio / "NO OUTPUT DEVICE", while the theme and other settings persist. Already tried: Set Defaults, other sample rates and buffer sizes, 2-channel 48 kHz format in Windows, disabling apps like Nahimic and NVIDIA Broadcast, updating drivers, reboot. Thanks!
