Gallery can't play slow motion video sound

[Adi0]

OK so I've tested this, slow motion videos recorded with camera then played in gallery don't play a sound but if I send it it has a sound. It also has the sound in Samsung video player and in Google photos etc...

Are you actually pressing the Play slow motion video at the bottom? Cause i can hear my sound fine.

[Adi0]

Yup I am. It doesn't have that speaker icon like other auto play videos.

Try go into Recovery Mode

Wipe Cache Partition x 3

Then Repair Apps

I've just done it. Still the same 😞 does it work in your gallery? 

[Mobz]

Yeah works fine in my gallery 🤔

Have you tried going into gallery.

Tap menu button, then choose About Gallery and see if perhaps there's an update that may resolve this situation?
