If you are getting an error such as

Assertion failed: !FAILED(hr) && "Failed to find supported audio format!"

Assertion failed: !FAILED(hr) && "Failed to find supported audio format!"

Assertion failed: !FAILED(hr) && "Failed to activate audio client!"

Assertion failed: !FAILED(hr) && "Failed to activate audio client!"

in your

Natives.log

Natives.log

, there is an issue with your audio device (your speakers/headphones/etc.).
Things to try:

Terraria and tModLoader really don't like it if you have no audio output. If you don't have one connected, try connecting one.
If you have an audio output but you are getting the error, try switching to a different audio device (different speakers, headphones, etc.)
Make sure your audio output rate is less than or equal to 48000 Hz.
If you are using Voicemeeter, you need to configure your A1-A5 devices.
If you have Sony INZONE headphones, try setting the output device as "Chat" instead of "Game".
Try the IAudioClient workaround in the tModLoader FAQ.
