Does anyone have a problem with AC3 on LiveTV? No DD5.1 in LiveTV but movies from the NAS no problem.
When I switch to OMXPlayer DD5.1 is fine in LiveTV

Build #0321

Edit: 
I am using passtrough via AV Receiver

There is no passthrough anymore for live streams since v17 IIRC. Reason is, that for live streams there is not enough buffer to handle passthrough well. You have to enable AC3 transcoding if you insist on an AC3 stream being sent to your TV or if you use SPDIF connection. But if you don't need SPIDF, there is no technical reason to require AC3 passthrough for liveTV since sound quality of 5.1 PCM will just be as good/bad. 

First, thanks for the answer.

I use neither PCM cable nor SPDIF but HDMI and I believe that it had worked in earlier versions of v18.
I will test an older version.
