### What Red version are you using?

3.5.22

### Cog name

Audio

### Command name

play

### What did you expect to happen?

I expected the bot to play the audio of the video in the channel them and I was in.

### What actually happened?

The bot did not played any audio and produced an error message in the discord channel where I issued the command. The error message is:

```
Nothing found.
This video cannot be loaded.
```

### How can we reproduce this error?

1. (Install, configure and start red: `python -m pip install -U Red-DiscordBot`, `redbot-setup`, `redbot `)
2. Enable the Audio cog: `[p]load audio`
3. Wait for Lavalink to be installed and connected
4. Join an audio channel in the server and have the bot play some music: `[p]sing` (or `[p]play https://www.youtube.com/watch?v=f9O2Rjn1azc`)

The bot does not play any music and errors with "Nothing found. This video cannot be loaded."

Note: Environment (fresh install):
```
$ lsb_release -cd
Description: Ubuntu 24.04.3 LTS
Codename: noble
```

### Anything else?

_No response_

Start by reproducing the failure with the Audio cog, Lavalink, and the reported YouTube URL, then inspect the Lavalink error in the bot logs. Trace the `play` command's handling of the failed lookup; done means the reported video can be loaded and played without the "Nothing found" error.
