Check Existing Issues

  • I have searched the existing issues and discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

v0.6.15

Ollama Version (if applicable)

No response

Operating System

Ubuntu

Browser (if applicable)

No response

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

Voice settings after updating to version 0.6.15, Supported MIME Types
When audio/mpeg is set, an error message appears: Oops! It seems like the file format you're trying to upload is not supported. Please upload a file with a supported format and try again.

Actual Behavior

Supported MIME Types

Even though audio/mpeg is set, the system still defaults to audio/wav for voice mode, and this setting seems to have no effect. Additionally, when no parameters are set by default, an error message appears: Oops! It seems like the file format you're trying to upload is not supported. Please upload a file with a supported format and try again.

Just switch and pull the dev branch. I'm using a Proxmox LXC version and just logged into the console, went to the root dir - in my case /opt/open-webui. GIT switched to dev branch and repulled.

Copying those file formats doesn't work for me unfortunately. For context, I have it set to use distil-large-v3 for local faster-whisper, but I'm getting that same "Oops" file fomat not supported error.

goto setings menu /admin/settings/audio
paste this into your audio settings windows and it will fix the error until its fixed in later release:

audio/mpeg,audio/wav,audio/ogg,audio/x-m4a,audio/webm,audio/webm;codecs=opus

fixed it for me!

This did not fix it for me, unfortunately. I still get the unsupported file format issue. Using distil-large-v3, I wish the people for whom it worked would add which model/method they're using that this worked for.

It's not working for me either. I'm running it on a Debian 12 server inside a Docker container. I pulled the :dev branch and copied the setup, but I’m still getting this error:
