exit();
}
sound s;
s.stream_pcm(d.read(1024 * 256), d.sample_rate, d.channels);
wait(1000);
}
Now returns a -10, I'm sure it worked some time ago but I can't remember when. What could cause this now?
Thanks,

It seams to work with wav files, but not ogg and opus. I'm sure it worked with ogg some time ago.

Hi,

Pretty sure the comment in sound.cpp line 779 explains the root of this one:

// Note: We used to pass on_tell_datastream here until miniaudio update Jan 8 2026, if something breaks with raw decoders and end checking, look here.

Basically for certain decoders, we need to be able to pass on_tell so that the decoder can determine the size of the file. Luckily, miniaudio already fixed this in the next upcoming release! Once that's out, we can easily resolve this issue. If it becomes a serious problem, I can create a miniaudio VCPKG overlay port in a bit that patches the passage of on_tell into miniaudio until such time as the update on miniaudio's end is released.

Thanks for the report!

Hi Sam,
It's not urgent, I just tried the tests and came across it.
It's a cool feature though, but I don't think you need to work on this right now.
