OS: Win10
PsychoPy version: 2023.2.3
Standard Standalone Installation? yes
Do you want it to also run online? no
What are you trying to achieve?:
- I’m attempting to reduce the volume of a movie component but it is unresponsive to the Volume field. Even when Volume is set to 0, it plays at full volume.
Context/Settings:
- The audio library is set to pbt
- Audio latency priority set to 1
- Force stereo is on
- Video is an mp4
- Experiment is being run locally
- Volume controls are working fine in sound components of my experiment in other routines.
What did you try to make it work?:
- I have adjusted the volume via the component settings in Builder.
- I made an experiment with nothing other than a single movie component to see if it was a product of how it interacts with other routines
- I have adjusted the audio latency priority settings.
- I separated the audio file from the video and uploaded a movie with no audio along with a sound component containing the audio. The volume setting on the audio did not work, even when disabled.
Link to the most relevant existing thread you have found: I couldn’t find anything about a similar issue.
What specifically went wrong when you tried that?:
There are no error messages to report, these attempts have not altered the volume in any way.
UPDATE: I couldn’t figure out how to fix this problem in psychopy so I edited the volume of the movie itself (reduced to 2%) using MovieChamp. This was an effective work-around.
