Nobody is using a part like that for any speaker output in a cell phone, let alone a laptop. Modern speaker drivers are closer to 8-12W (even in cell phones) so the wimpy 400mW of that device is worthless. It’s also in a package completely unsuitable for a cell phone, and doesn’t have any of the integrated jack detection that is needed in modern 3.5mm audio codecs.
Also, there can be many reasons for removing the headphone jack. I personally think the theory that the primary motivator was to drive additional sales for headphones is silly. It’s purely a cost play and the manufacturers decision to say that Bluetooth headphones are finally good enough.
