Premiere not playing back any sequences

[klmarlow]

This has shut me down for the whole day, so any help would be greatly appreciated. I'm hoping it is something simple that I've missed, since it was all working fine just yesterday. I hadn't installed anything new or updated anything before encountering this problem.

Symptoms:

⦁ Can't play any timeline/sequence. The play button changes but the CTI doesn't move and no playback ocurrs.

⦁ When I try to save, the  program locks up.

⦁ When I exit, Task Manager shows the program is still running. I have to manually terminate the program.

Steps to resolve:

⦁ Restarted machine. No change

⦁ Opened other projects. No change

⦁ Uninstalled all versions of Premiere (2017 & 2018). Restarted then reinstalled 2018 12.1.1 only. No change.

⦁ Ran Malwarebytes and restarted. No change

⦁ Installed back to CC 2018 12.0. No change

⦁ Uninstalled 2018 again, restarted, ran Windows update, restarted and reinstalled 2017. No change

⦁ Updated Nvidia driver to 397.93 (enterprise stable). Restarted. No change

⦁ Changed Nvidia 3D global preset to "3D App - Visual Simulation". No change

I would have a look at your audio hardware setup.

That worked! Thank you very much.

As to why, makes no sense to me. I have no Idea what could have changed to make it not work all of a sudden.

What a pain.

I often find that windows and graphic card updates changes all my audio settings. I have an nvidea card driving HDMI monitors and after updates I find the audio has switched to one of them instead of my ASIO Blackmagic card.
