One Cubase project went silent, while the others still played fine.
Spoke to a client in the US who was having a problem with no sound being heard in a Cubase project that had previously been working fine.
My process to diagnose and solve this problem:
- Checked through his Cubase Studio Setup and Audio Connection panels and couldn’t find any problems.
- Asked the client to check his hardware connections. The USB and cables to the speakers were plugged in correctly.
- Checked that audio played in Windows without Cubase running. Played back fine.
- Checked the sound was working in his other Cubase projects.
- Opened the offending project and created a new instrument track. This also played fine.
- Checked the Mixconsole and found that the Stereo Out connection for all the other projects in the track were missing.
- Reassigned the output connections and sound was restored.
I discussed with the client the likely cause and worked out that it may have happened when the client unplugged the audio interface while Cubase was running and then tried to troubleshoot the problem himself.
I used the remaining part of the hour to help my client take screenshots and notes of the correct audio settings in Cubase, so he could solve the problem for himself if it happened again.
Common questions
Why is there no sound in Cubase?
First check whether it’s every project or just one. Here only one was silent: its tracks had lost their Stereo Out connection, and reassigning the outputs brought the sound back. If every project is silent, start with this guide to fixing Cubase audio output.
Why is one Cubase project silent?
The Stereo Out connections had gone, possibly after the interface was unplugged while Cubase was running.
