What definition does 入る take in this sentence?


Consider this sentence:

> さっきなぜかマイクが **入らなかった** 。

This is translated as:

"For some reason the microphone didn't work earlier."

When I looked up the [definition](http://jisho.org/search/%E5%85%A5%E3%82%8B)
of 入る

  1. to enter; to go into
  2. to break into
  3. to join; to enrol
  4. to contain; to accomodate
  5. to have (an income of)
  6. to get; to receive; to score

Non of the definitions listed indicates "not working". Perhaps the closest one
would be 2. but it seems to indicate breaking into a place.

Can someone explain how 入る works in this sentence?

Shouldn't 壊れる be used to indicate it's not working and how would it be
different from 入る?




「入{はい}る」 means " _ **to be turned on**_ " when talking about electric devices.

Likewise, 「入{い}れる」 means " _ **to turn on**_ ".

> "The microphone didn't get turned on for some reason a while ago." or
>
> "I couldn't turn on the microphone for some reason a while ago."

As far as pure grammar, the original sentence means the first of the two
translations above. 「マイク」is the subject of the original sentence.
