The “Play” button in the sound block buttons does not play sound. I am also unable to scrub audio while grabbing moving the the frame slider as specified in these tutorials:
FFmpeg is selected. Multiplex audio, the little speaker, Sync and scrub is Enabled. (please see attached screen shots)
I am working in Ubuntu Linux with Gnome. If I export a mpg test file please audio works fine. i am just unable to scrub/preview it to sync it to animation.
Any suggestions or links would be greatly appreciated!
Hello
Linux, Blender and sound it’s a bit special?!
Have you tried sound in the Game engine? Probably it’s working?
Anyway start Blender from the console like this and tr again:
blender -g noaudio
Bye
I tried “blender -g noaudio” No audio played but there were no error messages showed in the terminal window.
edit:Wait! terminal showed this when i quit blender
user@LinuxLappy:~$ blender -g noaudio
guessing ‘blender-bin’ == ‘/usr/bin/blender-bin’
Compiled with Python version 2.5.1.
Checking for installed Python… got it!
Couldn’t open audio: No available audio device
Saving: /tmp/0001_0030.wav totlen 211724

How do I test sound in the Game engine?
What is the proper setting for Audio mixing buffer under “System and OpenGL”?
After i preview the animation i select the the scene button and the the sound button and enable scrub, sync and mixdown.
then in i click the render button, and on the format tab i select “ffmpeg”, on the video tab i select “mpeg-2”, and in the Audio tab i enable “Multiple Audio”, “mp2” and Bitrate 128.
Then in the Anim tab i click “Do sequence”, “Do composite” and then the big Anim button.
i got it from a Ubuntu bug report, it sets some blender variable to use the ubuntu alsa drivers and then starts blender in no game audio mode. the “&&” separates the two commands like a hitting the enter key.
