I'm having a problem in the timeline regarding the next frame keyboard shortcut. I'm trying to lip sync an animation with audio, but the audio won't play while moving frame by frame - only while dragging through the timeline with the mouse. Also my audio is set to stream. I just switched computers, and my old computer allowed me to hear audio on single frames while moving frame by frame with the keyboard, and this one does not. I feel like there's a setting I'm missing, but I can't seem to find it. Any help would be great!
I'm having this problem too. I can only hear the file play when I hit play or enter, not even by dragging/scrubbing through the timeline. I'm at AS 3 and set to Streaming. I read another thread [https://community.adobe.com/t5/Animate/Adobe-Animate-CC-Cannot-Import-Certain-MP3-Files/td-p/9287497] which may help you as it references Windows settings on the app itself as well as changing the sample type to 48000 Hz in a program like Audition (maybe the free Audacity if you don't have), and the bit rate also being an issue if not a multiple of 11 (this is not my specialty, I'm just repeated possible solutions here for you). I'm waiting myself to hear different options, as I tried changing those settings, and even exporting to WAV file format, but when in Animate, I can't even show the WAV file to import, and the file I changed the sample type to 48KHz in, and kept as an MP3, Animate refuses to import to even test out whether this is my 'hearing' problem.
Flash / Animate have never had such function to play audio when moving back and forth with the keyboard.
They have always played Stream Audio when scrubbing the play head.
To avoid any sync surprises, audio has to be prepared in 44100 Hz, 16-bit, WAV PCM format before import.
(Not 48kHz as another posrer in this thread incorrectly points out).
If you still hear nothing, the problem may be somewhrere with you audio settings at OS level.
Hope this helps!
If you use the scripts in that thread, be sure to use the revised versions, not the initial versions.
