different speed playing mp3

[ClaudioFoscan]

hi

i got a exp32-s3 setup with a max98357a playing mp3s from a sd-card. i updatet some of the librarys, inluding your audioI2S lib, recompiled and testet the player. i got some strange behavier:

mp3 with 32Bits, 48kHz Samplerate and 1Channel (Mono) and a mp3 with 32Bits, 48kHz Samplerate and 2Channel (Stereo)

the single Channel file plays double speed! was not the case with the old Librarys ...

is this a known issu?

thanks for digging in, i'm not that good in coding to figure it out where this comes from ...
