(This function is part of SDL_mixer, a separate library from SDL.)


Play an audio chunk on a specific channel.

Header File

Defined in <SDL3_mixer/SDL_mixer.h>


int Mix_PlayChannel(int channel, Mix_Chunk *chunk, int loops);

Function Parameters

int channel the channel on which to play the new chunk.
Mix_Chunk * chunk the new chunk to play.
int loops the number of times the chunk should loop, -1 to loop (not actually) infinitely.

Return Value

(int) Returns which channel was used to play the sound, or -1 if sound could not be played.


If the specified channel is -1, play on the first free channel (and return -1 without playing anything new if no free channel was available).

If a specific channel was requested, and there is a chunk already playing there, that chunk will be halted and the new chunk will take its place.

If loops is greater than zero, loop the sound that many times. If loops is -1, loop "infinitely" (~65000 times).

Note that before SDL_mixer 3.0.0, this function was a macro that called Mix_PlayChannelTimed() with a fourth parameter ("ticks") of -1. This function still does the same thing, but promotes it to a proper API function. Older binaries linked against a newer SDL_mixer will still call Mix_PlayChannelTimed directly, as they are using the macro, which was available since the dawn of time.


This function is available since SDL_mixer 3.0.0
