Hardware News   Hardware News : Troika NG Sound system
   posted by Troika on 8-Sep-2006 22:24:09 (8938 reads)
Troika NG would like to announce that we have chosen a fine industry standard AC97 codec, the AD1888 manufactured by Analog Devices, marketed under the Soundmax® brand. The sound codec is used in our Project “Prometheus"/ Amy’05.

This fine device brings many features (including AD’s special filters) used in Asus motherboards and Creative products etc.to the Amiga community.

Read more for details...





In our design we use 6 audio connectors to provide a full surround sound system: Front, Left side, Right side, Center, Surround Sound via audio jacks and an SPDIF output through a standard RCA connector. We also include an internal Intel™ HD-Audio standard header for case connections and so much more!

Some technical details: “The AD1888 is a 6 channel (supporting 5.1 surround sound) AC'97 2.3 compatible codec. It features SPDIF output, variable sample rates, 20-bit DACs, and multiple stereo analog inputs along with many cost saving features including: integrated headphone amplifiers, selectable microphone inputs with built-in preamplifiers, jack sensing (with auto-topology switching), hardware channel spreading and downmixing, as well as crystal-free operational modes.”

For more information visit
SoundMAX
PDF’s are available on the Analog Devices web site, however we have made available the PDFon our website.

@Troika

You should know by now we are all visually inclined and therefore always hunger for pictures even if they are still work-in-progress

Seems the perfect good quality component for the design (like the thundra chip)

Very good Troika

Could a moderator please fix the SoundMax link? It currently says "http:// http://www.soundmax.com/" (complete with embedded space).


Fixed!

Maybe Rogue, or Dave AE can answer from a software point of view?


Good point. Are there DRIVERS for this chipset yet? Is DaveAE working on them?

@DaveAE

Hi Dave,

I sure hope they give you a new board (and chip docs) so you can do the drivers.
Soon..

@Samwel:

SoundMAX is an AC'97 compatible chip, so the drivers should be similar to those for built-in sound on AmigaOnes. I don't know enough about the standard to know if you can just use the same drivers (with maybe some loss of functionality), but I believe that Dave should be able to reuse most of the code in the existing drivers.

No, only some code. You have the audio controller and the codec. Usually they are separate chips, except for very few, like the cmi8738.
You can't use the via686b (which acts as an audio controller) driver on the Troika board since it most likely doesn't have one.

The ac'97 is present on for example the Terratec 512i, SoundBlaster cards with emu10kx and lots of onboard solutions. They all require different drivers.

Hi,

The Prometheus developer documentation still needs some updates, but if you want any advance info, contact me via email or if at the show next week, ask me.

The AC97 codec interfaces via the new southbridge we added, full details to follow in the press release.

Ian

@stedy

I really wish you guys had picked a different codename. I read your post and thought "what does the Prometheus PCI expansion board have to do with the Amy '05?" - then I realized that Prometheus is also the Amy'05...

Yes, if there is one thing they could do, then it is
not to use that name, it is to confusing, see link:
