What amp is this?

[NickB]

I bought a pair of Insignia Bluetooth powered speakers (NSHBTSS116) for my kid's room and they don't sound half bad given the drivers used. Curious if any of you know what amp is being used in these.

Higher res pics of the boards are at this link:

Thanks in advance.

Pics are blurry when zoomed in but I think I may have found it:

AS5731 Datasheet, AS5731 PDF - Alldatasheet

Any thoughts on this one?

its 4channel class d amp that has builtin DSP, it can be configured as 4ch, 2ch btl, or 2.1, at your board its 2channel btl.
