    After Effects error: could not allocate sound memory

    frankbuckster68 Community Member

      I get an error in an timeline in After Effects CS5.5: "After Effects error: could not allocate sound memory ( 26 :: 392 )" It locks my timeline totally, and keep popping up every time I say "Ok".

       

      Any solutions for this one?

          What footages are you using? Any specific audio equipment? Did you check your AE prefs and QT audio settings?

            Footage is mainly ProRes422, DV-PAL and Uncompressed 4:2:2. Tried to convert all odd formats (MP4, AVI, WMV) to ProRes422 with no luck.

            Working with different cache settings in AE right now...so far no luck on that.

            Audio is mainly 48kHz, 16 bit and 24 bit, stereo. Audio only is AIF or WAV, some video files may contain other formats. Is that a common issue?

              It's not common, that's why I'm asking... Did you by any chance install a QT component used by anotehr app? I remember at some point such an issue existing with some speech recognition software....

                Good answer! No, I did not install anything during this project, simply just worked on it for 1+ week and suddenly yesterday the error message popped up.

                My comp is growing bigger and bigger, It's around 120 layers / precomps in one timeline. This moment I rendered all audio out, to AIFF 48kHz to make sure it isn't a sample rate / audio format issue - but still the same Some guy suggested enabling Disk Cache, it was off (isn't that on by default?) but switching it on didn't help either.

                 

                I have started rebuilding my whole comp again, with a lot of pre-renders instead....time-consuming but hopefully it helps

                 

                Still, I would like to know what causes this problem!

                  Mmh, could it be that your media cache is simply full or your project exceeding its limits? that would be the last thing to investigate. Perhaps flushing the media cache from ther prefs will do miracles...

                    I have already flushed my cache, and having AE to conform all media again - no change I have increase the Disk Cache size to way above the project's previous size - no change.

                     

                    Strange, huh?

                      Hi,

                      Has Frankbuckster68 worked out his problem?

                      I am interested in because I think I have the same one.

                      Actually I'm using AE for the first time and I can't hear any sound track (MP3 or .AVI)

                      Here is the workspace I'm working on.

                      Thanks for help,

                        Hi,

                        I've got it by now. I have understood that we mustn't use the space bar but the point key on the numeric keypad...!

                        Very sorry.

                        Jean-Paul

                          I'm having this issue and I can't get the stupid window to stop popping up. I'm completely unable to do anything in my timeline. I CAN click on one of the menu items at the top if I'm fast enough and I've tried purging "all" as well as cache and video memory (I've tried them all basically) and it makes no difference. The window just pops up again immediately. I've made my cache larger (way larger than should be needed) and nothing comes of that either. Why does AE have an error that prevents you from doing anything to fix it? I've closed the project, quit AE and restarted, to no avail. Am I going to have to trash my entire project and start over? Frustrating!

                            Well, I solved it by using the menu command "Lift Work Area". I had never used it before but it removed the layer that was causing issues. Luckily it was one that I could just place right back into my timeline with very little work to redo. I have no idea if this was the proper way to do it or not, but it's pretty frustrating that it had to be done at all, and just as frustrating to discover that I couldn't find a solution ANYWHERE.

                             

                            So basically I'm posting this for anyone else who winds up in my situation and can't find any real help.

                             

                            Adobe: you've got to fix problems like this. Seriously. I love After Effects and have been using it for several years now. Admittedly I've never encounted this before, but you can't have a window pop up indefinitely, preventing you from doing anything about it. It's amazing that I was able to do anything at all. You've got about a fourth of a second to click on the menu bar before the next error window pops up, and a fourth of a second might be a generous estimate.
