It worked fine on my iPad 2. Apple killed it, and then withheld the feature from me until I brought a new iPad.
It would be like if they reached into your computer and locked the sound output to a certain volume, and told you to fix it by buying a new macbook.

As the lower layers get commodified, every OS vendor does that. Examples of features that, at one time, used to be third-party:
- graphics libraries
- font technologies
- audio synthesis
- MP3 encoding
- video playback
- text-to-speech
- speech-to-text
- TCP/IP support
- printer drivers
- antivirus
