Duncan Perry Posted March 13, 2022 Share Posted March 13, 2022 Hi all, Im running 2022.02 on windows 10. Cakewalk seems to have developed an issue recently where it won't playback properly, and it seems to do this on both complex projects with lots of audio and vsts running as well as simple projects with just a simple loop or suchlike - way i'm getting at is the content of the project seems to bear no influence on the problem. The issue is, sometimes I will load a project and press play, the transport bar will not move and it'll play the first second or so and then the audio will stop suddenly. Sometimes shutting down cakewalk and starting again will fix it, other times it won't. I have also tried running Cakewalk as admin, but that doesn't seem to help the issue. Anyone else seen this issue? Link to comment Share on other sites More sharing options...
Will. Posted March 13, 2022 Share Posted March 13, 2022 (edited) Nope. That's just CPU overload. Everytime you load an effect in a project it consumes system resources. Do you have an interface perhaps? If so, you can increase the buffer size to 512, but this will introduce a slight delay when doing composing work (not playback.) To locate this: Go into Preferences>Driver Settings. You will see a blue slider. You can also change it in the Asio Panel button.

bitflipper Posted March 14, 2022 Share Posted March 14, 2022 Will is correct. However, increasing the buffer size doesn't always solve the problem. Sometimes the root cause of CPU overload can be obscure. Often, it's a background process or interrupt service routine (ISR) that's hogging the CPU. Troubleshooting this kind of issue begins with a free diagnostic tool called LatencyMon. Interpreting the results can be challenging, but there are some instructions on the Resplendence website that may help. What this utility does is measure DPC latency, the time it takes for your computer to process hardware interrupts. Interrupts take priority over pretty much everything else, so if they're taking too long it can keep your system from handling audio properly. Sometimes it's a sloppily-written driver, sometimes it's a broken interface card. The most frequent offenders are network adapters, in particular wireless wi-fi. But run the tool and report back what it tells you. Link to comment Share on other sites More sharing options...
Duncan Perry Posted March 15, 2022 Author Share Posted March 15, 2022 Here is the report - I have changed the preferences->driver settings->mixing latency to the following Buffers in PLayback = 2 (can't alter this) Buffer size - 5.3ms, 513 samples and Asio reported Latencies are input 4.6ms, 440 samples output 6.6ms, 536 samples Yet, i am still having problems with it ____________________________________________________________________________________________________ CONCLUSION _________________________________________________________________________________________________________ Your system appears to be suitable for handling real-time audio and other tasks without dropouts.

Will. Posted March 15, 2022 Share Posted March 15, 2022 (edited) You might want to add at least another 8GB of Ram to it. Do a test and report again. DISABLE 4 Effects to confirm what we are saying - any of the following manufacturers. iZotope, Waves Abby Road Reverb, Lurssen Mastering Console and maybe Fabfilter EQ3. Cakewalk LP, MB and Adaptive Limiter First try this with all the effects on your Mastering Channel. Edited March 15, 2022 by Will. Link to comment Share on other sites More sharing options...
Duncan Perry Posted March 15, 2022 Author Share Posted March 15, 2022 Unfortunately, the RAM is not upgradable. Dumb question i am sure - do i have to run the cakewalk project and the LatencyMon at the same time? Regarding the VST/effects you've listed, as per the OP I am having the issue with complex projects aswell as very simple ones. Link to comment Share on other sites More sharing options...
Will. Posted March 15, 2022 Share Posted March 15, 2022 8GB ram is a little on the shy side for just even some basic 12/16 track, 8bus project with effects like those mentioned above including some VSTi such as Kontakt etc. That's not to say you can't use them. Regarding the test. If it will help you identify things for future mixes - Yes, you can run the LatencyMon when you disable these effects - only those on the Master Bus (don't delete them.) Have you tried to reinstall the drivers of your interface again? Link to comment Share on other sites More sharing options...

Maybe not the reason for your issue but worth to check. Link to comment Share on other sites More sharing options...
