INFO: OpenAudioDevice failed: WASAPI can't activate audio endpoint:

After launching the game I get a display saying "No audio found. Disabling all audio" I have tried all of the other fixes in the forum, and nothing seems to work in my natives log I get this message:
INFO: OpenAudioDevice failed: WASAPI can't activate audio endpoint:

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!" or Assertion failed: !FAILED(hr) && "Failed to activate audio client!"Assertion failed: !FAILED(hr) && "Failed to activate audio client!" in your Natives.logNatives.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.

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

After doing that I do have audio, but it seems to laggy, see video sounds like there is still a connection issue

how? i have the same issue. tried the IAudioClient fix and the directsound/winmm fix but nothing worked. i also have laggy sound.

worthy-azureOP•5/15/25, 6:14 PM

did you restart your computer each time after adding the environmental variables?

worthy-azureOP•5/15/25, 6:14 PM

this is what worked for me

worthy-azureOP•5/15/25, 6:15 PM

intialilly when i tried with winm it didnt work but after i restarted my pc it did work, I would try them both again and see if either work on your system, one of the options made the sound worst while the other fixed it
