Audio Engine support?
Will Audio Engine from 12.1 ever make it into the Pi version? It seems to be the only option for DTS-MA and Dolby True-HD playback.
If it's too demanding to use for all audio, could it optionally (checkbox?) just be used for full audio pass-through? |

Re: Audio Engine support?
HD formats depends on RPi firmware and so fa this has no support and it has low priority to make it happened.
It is just needs more time ~~~~>>>Please always follow rules and read before you post<<<~~~~ |

RE: Audio Engine support?
I remember the (stalled) possibility of DTS downmixing in hardware, which would require a firmware update. Would using Audio Engine purely for pass-through still require firmware support?
If not, I might be tempted to have a hack myself. For personal use I could manage with just pass-through, but for general use it would be better to fall back to the existing sound system, if possible. If it's all a non-starter I'll wait until those who know the codebase better get to it |

DTS and DD is working, downmix or pass-through but the DTS-HD MA or True-HD is not available. This required a firmware update. To do this would required couple of weeks work of someone with access to Broadcom code

Thanks for confirming -- I was struggling to find any details elsewhere.

I have a feeling that dom is about to pull a rabbit out of his hat on this one.

Re: Audio Engine support?
unfortunately it is not just in his(Dom's) hands.
There are mire people behind and it is required a lot of time from thus guys which they simply do not have as there are more important things to do and they are pushed to do those.As usual, time and money,thats what is all behind. But the possibilities are there so lets hope they gonna make it one day. As us ~~~~>>>Please always follow rules and read before you post<<<~~~~ |

I'm not sure were you get that impression as there hasn't been any movement on it since it was first brought up.

I don't think money would be as much of an issue because it seems that there are plenty of people willing to donate/pay for this to be implemented. |

Yeah, but go to the next page and you'll see:

RE: Audio Engine support?
thats what I said, time and money. The RPiF do not go to invest money(pay the person who can implement the code into RPi Firmware). And the donation of few (even counted in 100's) is not going to change it
... BTW we have this all covered, and we keep an eye on this (i have red the thread few times since was opened ) ~~~~>>>Please always follow rules and read before you post<<<~~~~ |

And the donation of few (even counted in 100's) is not going to change it Wasn't sure which comment you were referring too Although, I think that a few (just 100's) that would donate is probably a low-ball number. However, it might be worth while for the RPiF to put this to a poll to see if this might be worth giving it a higher priority. Quote:(i have red the thread few times since was opened ) Yeah, but if your like me you've probably slept since then. |

RE: Audio Engine support?
DTS-HD bitstreaming on the Raspi's HDMI port appears to be a legal issue rather than a development one. The DTS licensing authority say it's covered by one of their patents, and Broadcom can not allow firmware that muxes DTS-HD streams into the HDMI out without a DTS Licence.
Unlike the MPEG-LA, the DTS-LA will not offer per-user licences for DTS. This means it's very unlikely to ever happen, because the foundation will not be able to afford a DTS licence covering every board manufactured. (The likes of Nvidia can just absorb the cost so they can allow DTS-HD bitstreaming on all their desktop graphic cards.) On a side note... Getting AudioEngine into a working state on the Raspi would be a huge benefit for people who want to use USB soundcards. |
