The specs at the sony site list capability to play these disc formats:

Ultra HD Blu-ray, BD-ROM, Stereoscopic 3D (profile 5), SA-CD (SA-CD/CD) Playback, DVD-Video, DVD-Audio, DVD-R, DVD-RW, DVD-R Dual Layer, DVD+R, DVD+RW, DVD+R Double Layer, CD (CD-DA), CD-R/-RW
Technically, a home burned DVD-A would have to fall into one of the DVD- or DVD+ categories listed. So unless the unit specifically restricts burned DVD Audio, my guess is it will play your burned disks.
Did the older model play burned DVD disks but just not burned DVD Audio disks specifically?
