Electronic – Indentifying a JL chip in a Bluetooth


I'm new to electronics and my Bluetooth speaker broke and want to fix it. This is the chip I think I need to replace.

JL BT chip

Can anyone help me find this chip's datasheet? I just need to know what each pin does.
I have tried to find it but I couldn't find any info on it. Maybe because it's from a dirt cheap speaker.

The manufacturer is Zuhai Jie Li (珠海杰理) Many of their part numbers start with ACxxx


...but this particular part does not appear to have an publicly available datasheet.
