OSC 440 Play Sound
Play a sound file, mintty's extension.
OSC 440 ; Pt ST

- §8.3.89 OSC – Operating System Command, p. 51
- Specification
- mintty's control sequences: audio support
OSC 440 ; Pt ST is mintty’s: it plays a sound. Pt is the name of a .wav file in the sounds directory of mintty’s configuration, or the path of one, optionally followed by options separated by :. With async the sound plays while the terminal goes on with its input; nostop skips it if an asynchronous sound is already playing; and loop plays it over and over, asynchronously. An empty Pt stops a sound playing asynchronously. mintty added it in 3.5.2 and marks it experimental (control sequences, termout.c). It is not the bell: nothing rings.
A default xterm has no OSC 440 and ignores it (the OSC numbers it knows). The cases follow xterm.
libghostty-vt does not recognize OSC 440 either: its OSC parser in osc.zig has no state for the number, so the string is dropped, and the cases pass.
