Hi,
I recently discovered that when I use autopilot mode, it causes severe sound problems whenever I play video files (MP4 and MKV) that contain AC3 audio in VLC. More precisely, it'll play fine until I pause playback or skip to another position, whereupon it starts to crackle. I tried several builds of VLC (and changing options in BTS2015), but the problem persists.
Interestingly, it doesn't happen when I switch to film mode manually before starting VLC, so it must be related to autopilot mode itself!
Playing the same files in other players while autopilot mode is enabled works fine, too.
Specs:
Windows 7 64-bit Ultimate
Bitdefender Total Security 2015
VLC Media Player: 2.1.5 (latest)
