Audio recording hangs and causes drop out

i a project that was created in C11 and then opened in C12 i can’t record properly. when i start recording or go into punch in, the audio drops out briefly before going into record and recording a flat line. when i then stop recording playback stops but when i press play (not record) it continues recording. the only way to stop this is to switch off the rec enable on the track which leads to an error message:
when i load the same project into C11 everything is fine and no problem recording.
i tried all configurations of disabling 3rd party plugins, disable program preferences, deleting program preferences and permutations of these without being able to get rid of the behavior.

workaround for now is to work with this project in C11 only.

any insights?


If there is a DMP file in the given folder (Documents/Steinberg/Crash Dumps/), attach it, please.

If not, follow these instructions, please…

Generate a DMP file and share it via Dropbox or similar service, please.

Use Microsoft ProcDump utility to generate a DMP file, please.

  1. Please download ProcDump64 from Microsoft (~650kB) and extract the archive to a local folder on your harddisk.

  2. Run Command Prompt (cmd) as administrator (right click and select “run as administrator”)

  3. Navigate (in the Command Prompt) to the folder with the extracted procdump file.
    For example:
    cd C:\ Users \ \ Downloads \ Procdump
    Note: the dmp file will be written into that folder.

  4. Launch Cubase/Nuendo. You can work as usual. At any time, change to the command prompt and start procdump, to monitor Cubase/Nuendo for unexpected behavior (see next step).

  5. Launch procdump64 via Command Prompt:
    Cubase 12:
    procdump64 -e -h -t Cubase12

Nuendo 11:
procdump64 -e -h -t Nuendo11

The -h option will write a dmp file in case of an application hang. This might kick in too early sometimes, in case some action takes a little longer. Feel free to skip the “-h” option, if you are only up for fetching crashes.
The option -e will catch exeptions and the option -t terminations of the application.

  1. Prodump is now monitoring the Cubase/Nuendo process and will write a crash log, in case Cubase/Nuendo crashes or hangs. Perform the action that causes Cubase/Nuendo to crash and send us the generated crash dmp.

ZIP and share the DMP file via Dropbox or similar service, please.
