| Summary | HDMI audio won't pass ac3 through another device |
| Product | DRI |
| Version | unspecified |
| Hardware | x86-64 (AMD64) |
| OS | Linux (All) |
| Status | NEW |
| Severity | normal |

| Component | DRM/Radeon |

I have an AMD E-350 system (Radeon HD6310). When I connect it directly to my receiver and play a file with AC3 audio, the receiver properly switches over to Dolby Digital decoding. However, when I connect the HDMI to another device's pass-through (Vizio TV, Xbox One), the receiver stays in stereo mode and I get garbage audio. Other devices can send Dolby Digital through (e.g. I tried a TiVo Roamio through the Vizio TV), so I know it can be done. I'm guessing there's some bit of HDMI handshake not happening when the Radeon tries to switch modes and is connected to another device, but I don't know how to debug that. Please let me know what I can do to figure this out. I'm testing this with a trailer downloaded from hdtrailers.net, playing with either XBMC or VLC.
