Greetings.
Chinese chip. Cannot find Marked JL as manufacturer logo probably Jin Lin; part AB24BP24857 or AB24BP24 Handles Fm radio reception/scan, a microphone, bluetooth link, 1 channel output audio amplifier. Surface mount. If you have some search magic; I would appreciate a link that helps with its configuration.
Lives in a wireless speaker gadget that features a microphone with no instructions to enable the microphone. Vendor knows less, evading and misleading to answer.

The nearest I got is ---> https://www.eevblog.com/forum/projects/jl-bluetooth-ic-id/

JL may be https://www.zh-jieli.com
Likely the marking is not the IC HW number, but the embedded FW, so dead end.
Share an image of the IC, package & pinout may give a hint which IC is behind this.
