Amiga 600 and Workbench 3.2.1, No HDMI Sound.

Hi,
I have flashed my ROM with kickstart 3.2.1 and running Workbench 3.2.1 with RTG working.
I do not have DIGITAL-VIDEO sound through the AHI audio.
I changed my startup-sequence to play audio through the DIGITAL-VIDEO upon boot using the command line

Run >NIL: Play16 S:BootSounds/BootSample05.iff OUTPUT=AHI MODE=16842782

I used a small utility called Gaip16 from EXTERNAL LINK to get the correct AHI HWID.

Am I missing something or should I reflash the ROM back to the current Gold 2.15 version?

Thankyou,
Alexander.

The V2 accelerators do not output sound through DIGITAL-VIDEO. Only the V4 range can do this. Nevertheless AHI will work with Paula audio out through the RCA audio jacks.

I understand that the a device has been created to allow for sound to be redirected through the DIGITAL-VIDEO, called the PARASITE?

Is this device available?
If so, are there distributors for this piece of hardware?

Thank you...

According to team member Gunnar von Boehn stated in the post about the Amiga Vampire 2 on 29 Nov 2015 18:00...

Extra features:
  Not all might be enabled / will be enabled via update later
  * Digital Video Out
    Supporting up to 24bit truecolor and FULLHD 1920x1080 resolution
  * 16bit Audio
  * SD-Card is Hard drive

Does this mean that DIGITAL-VIDEO audio is available but not implemented? If so, isn't just a case of creating an audio driver?

Audio out through DIGITAL-VIDEO on V2 accelerators is not available and never will be. There is simply no more room left on the Cyclone 3 FPGA to add this feature.

Yes this was a list of ideas of which might develop.
As we also wrote, maybe not all might be enabled.
 
16bit digital audio is a feature which we did develop.
But it does not fit in the FPGA of V2 cards.
The newer V4 cards have a bigger FPGA and they have this feature.
The new V4 cards can also promote the Amiga display to DIGITAL-VIDEO.
