Failed to active audio client

I'm well aware that there's a list of solutions to this problem, but none of them have worked. I've done fresh installs, I've tried different headphones, I've tried the IAudioClient workaround. Nothing. The IAudioClient gives me the WASAPI error instead of the audio client error, which I think may have something to do with the fact that installation replaced 5 files, not 3 like the instructions said.

Update: after a little investigating, I cannot find the FNA folder. I assume that's something I should be able to navigate to.

If you 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 your with 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.

WSPI can not initialize audio client. Solved here: https://stackoverflow.com/questions/46835811/ffplay-wasapi-cant-initialize-audio-client-ffmpeg-3-4-binaries

FFplay: WASAPI can't initialize audio client (FFmpeg 3.4 binaries)

I am trying to playback a stream that is multicasted over RTP using ffplay on Windows 7 64 bits.
The computer that serves the audio over RTP runs:

ffmpeg -re -f dshow -audio_buffer_size 15 -ac 1 -i

UPDATE: FIXED!!

I'll be as detailed as I can (without being super repetitive) for anyone with the same issue desperately looking for an answer like I've been doing for the past week:

Download IAudioClient and follow those instructions, even if they look a little different (I had to replace more files than was indicated in the instructions but it still worked)
If that doesn't work on its own and it gives you the "WASAPI can't initialize audio client" error, follow those instructions in the link above. Both options (winmm / directsound) allow the game to run, but for me, winmm left the audio sounding awful while directsound makes it sound normal again. Make sure you restart your computer after implementing this change!

I also disabled a lot of my audio drivers (just the Nahimic ones) and did several fresh installs of both Terraria and tModLoader, but I don't think either of those steps are necessary.
