6ch PC Audio to FireWire (DVD-Audio)

[mitchwolos]

This is actually for my car.
It’s an Alpine F1 DVD-Audio headunit and DSP.
It has 16 channels of output for a 6 channel 3 way front/2 way center/2 way rears/2 way rear center.
It’s the only car audio DSP that will do active multichannel.
It uses a FireWire connection between the two pieces.
The FireWire is the only digital input into the DSP.
I’d like to use a PC as a supplementary source.
I’m looking for a way to send 6.1 channels from a PC into the DSP. Does anyone know of a PC driver that will emulate MLP/DVD Audio over IEEE 1394?

Essentially I want to use the PC as a player with a .vst upmixer (Penteo Perfect Surrround) and send those 7 channels into the DSP.

Is it this channel?

The 6 audio channels can be decrypted and then re-encrypted into an HDMI or IEEE-1394 (FireWire) signal and sent to the amplifier, which will then decrypt the digital signal and then extract the 6 channels of audio. HDMI and IEEE-1394 encryption are different from the DVD-A encryption and were designed as a general standard for a high-quality digital interface. The amplifier has to be equipped with a valid decryption key or it won't play the disk.

That is the format yes.

IIUC the stream must be encrypted. I very much doubt you will find a PC software for that. IMO DVD-audio product manufacturers had to purchase some license to be be able to use the technology. DVD-Audio is long time dead.
