I cannot see the small tick box to mute the audio on my layer in my project.

The little box in the layers panel to mute the audio is not there, this is only happening in this project. Please help!

Without any info about your system, your footage files and the audio contained in them, your audio preferences and so on we can't realyl tell you much. If the tick box doesn't show up, AE simply cannot access the audio and things there isn't any and there's no way to enforce any of that. You realyl need to fix the respective settings and/ or your files.

Should I give my specs for my PC? 🙂
