My premiere Pro has no sound playback. I changed the settings in "audio hardware" in the preference setting and uninstall and re-download premiere but I still have no success. I made sure the sound isn't on mute. I tried using the bar and tones sample file but still have no audio. I've been using Premiere for years and never had this problem before.
Have you recently installed the Newtek software or NDI driver? If you have, please check that “Preference>Playback>Audio Device…” dropdown is set to “Adobe Desktop Audio” and not to “NDI Output”.
If you still have an issue with audio playback after checking and changing that setting, please post a screenshot of the Preference>Playback section.
