"Peux-tu jouer quelque chose d'autre ?"
Translation:Can you play something else ?
It should. Did you try it?
If you did and it was not accepted try reporting it. Sometimes they listen :)
quelque chose is an indefinite pronoun. If it is followed by an adjective (in this case autre ), de or d' is inserted. The adjective takes the male form (neutral).
to Summerstor5. In this link you will find examples to see how "d'autre" translates to "else"
Would this be appropriate for referring to both playing music as well as one's ability to play sports?
