I have a Sonos 5.1 audio setup (PlayBar, Sub, and two Play:1's). Dolby Digital Plus is not compatible with Sonos, so I get no audio for anything being delivered in DD+.

I was hoping to avoid the need for a receiver, but as Netflix, VUDU, and other streaming services migrate towards DD+, it's looking like I might need one.

I have three devices connected to my Sony TV (KDL-55W802A) via HDMI, and an optical cable going from the TV to the Sonos PlayBar.

Can a receiver take Dolby Digital Plus and DTS audio sources and output it in DD 5.1 via HDMI to the TV? My TV will pass a DD 5.1 signal to the Sonos via optical.

Can anyone recommend a decent, but affordable, slim/small receiver that will do this?

Cant you just set your devices to dolby digital?

Unfortunately, not all my devices (most notably the Roku 3) have an option to specify Dolby Digital.

Do any of your other sources have Netflix, vudu etc. that does not support DD+ but uses DD. A video processor might be able to do this. The DVDO edge is probably the least expensive that might have this capability. You'd have to call them to ask.

I think I'm good now. The Xbox One just added Dolby Digital 5.1 support, which has all the apps that I was using the Roku for. Thanks for your help.
