Upload lossless m4a to Sony walkman without conversion using Windows 10?

Question

Windows 10 Pro, Sony Walkman NWZ-W273S, 4GB, v. 1.0

Uploading (256kbit)m4a 109mb without conversion and it doesn't play, on the other hand if I convert it, along with the upload, the size gets reduced with 20mbs.

Is there a way to upload the file without any conversion and still make it work?

Answer 1

According to Sony, that machine can only use AAC-LC DRM-Free format.

As you haven't given us the full encoding information of the file you are trying to play, the only assumption we can make is that is isn't that format & must be converted in order that the machine can play it.

Which only leaves me with…
You'll have to ask Sony why it can't play that, as all indications are that it ought to be able to
