Different players have different init routines. pla24s is a "normal" player (with full options). It looks for me that the player you have ripped is a "fast" version (probably pla24b or pla24d).
My advice: stick with the "fast" version. Most people does not need all the options of full version. The advantage in speed is also important.

jaskier... but in the sources there is no explanation what the init parameters are...

ldx = hi-byte of music data
ldy = lo-byte
accu = ???

what are the A parameters??? how do i initialise the fast version? the standard version?

You mean this player by Fox? But music with this player sounds different, tahn with standard player, in my opinion - worse. Heaven: you should just try, if the music plays correct with the fast player...

Sorry, but I thought that the sources are "self explanatory" :D

Fox player doesn't have any init. It has to be assembled with music address.

Usage of fast player:
lda <music
ldx >music
jsr init

Usage of normal player is much more complicated, it requires 2 calls or even 3 if you use samples.
