Hey v0j4,
Thank you for reporting this issue. I have a few questions you could answer to help me troubleshoot.
- When you say no sound device, what are you referring to? i.e. Headphones, Speakers, or actual Sound Card?
- Have you tried testing this issue in 4.10.2 to see if it still occurs there?
- Can you confirm it is directly related to not having a sound device? i.e. Do the movies play properly when there is a sound device?
Thank you,
