When I have different Epson projectors connected in my wireless network, I can wirelessly send audio with video to my PowerLite 915W, but not to my PowerLite 826W or PowerLite 826W+. What should I do?

• The PowerLite 826W/826W+ and other earlier Epson projectors do not support audio via a wired or wireless network connection. These earlier Epson projector models cannot be updated to support audio over wired or wireless networks.
