How can I use setStartSec() ?

[vintagecardriver]

Hello,
when I'm trying to start a song at a predefined moment for example 50 seconds after the beginning of the song with "setStartSec(50);", I'm getting the fault code: 'setStartSec()' was not declared in this scope.
How can I use "setStartSec()" in the right way?

Just send the PCM output to a TimedStream

I'm sorry, but I'm not an experienced programmer.
Would you be so kind, please and just give a short example, how to use TimedStream in a sketch, when song with index 33 (33. File on the SD Card) should start 50 seconds after beginning of the song?
I've tried

'TimedStream(AudioOutput &o, 50, -1);
player.setIndex(33);'

but hat no success. The fault message is: expected primary-expression before '(' token

I've also tried:

TimedStream timed (source.index(), 50, -1)

and the error message is no matching function for call to 'audio_tools::TimedStream::TimedStream(int, int, int)'

Perhaps you could add the TimedStream call please in your sd-i2C-example for understanding how the TimedStream will work. Where and how could I add the TimedStream call in that code?

You would make me very happy with a little help!

// setup output
auto cfg = i2s.defaultConfig(TX_MODE);
i2s.begin(cfg);

// setup player
player.begin();
}

void loop() {
player.copy();
}
