Support Reqest - Automatic Suspend

Ubuntu 20.04.1 LTS, suspends automatically and then there’s no sound from the device. The sound output switches to Dummy output and can’t be reversed. Need to restart to switch back sound.
Help me with automatic suspend and the other problem mentioned.
If I suspend it manually, then the sound problem doesn’t occur. It is there only when it suspends on its own.

This looks like a technical support request.
