Hello, I have a question for you. I have a SoundBlaster Audigy RX 5 sound card with SPDIF output and now I am wondering if I can somehow force a Dolby Digital signal from my computer. My amplifier uses Dolby Pro Logic every time I work with 5.1 in Adobe Audition 2023 even thought I am trying to mix Dolby Digital and I am sending all the channels it needs.
My current channel mapping in Audition:
Dolby Digital is working fine when I play music that I mastered and exported as AC3 from Audition the thing is I don't get Dolby Digital straight from Audition when I am trying to master 5.1 it only works in Dolby Pro Logic so when I am listening to center channel in Audition, I cannot hear anything from my speaker also when I start playing music from channel left and right it suddenly starts playing on center channel because of Dolby Pro Logic. I don't know how to explain it. Maybe Audition is just too basic to always output 5.1 sound in DD. If I am trying to master 5.1 it's really hard when the software that I use is not outputting Dolby Digital signal.
This is my current audio card configuration:

I exported the WAV file with all 6 channels encoded (i think) then I used an open source converter that converts WAV to AC3 file format and the Dolby Digital actually works I am getting proper DD signal, It even works on my good old Technics SA-DX940 all channels are present and working
Audition has never had a Dolby 5.1 encoder built into it, and that's primarily why you can't output 5.1 raw wav files directly. If it did have one, you wouldn't be able to afford to hire the software - and that's primarily why it hasn't got the facility.

I'm sorry, and I know I am gravedigging an old thread, but this is forgetfully false at best, and revisionism at worst.
Adobe Audition 2015.2 could export to both Dolby Digital AC-3 and Dolby Digital Plus E-AC-3 in a variety of bitrates - 384-1024 for E-AC-3/DD+ 7.1 (32 kbps per channel minimum for all other layouts); AC-3/DD 640kbps total max (56 kbps min/ch). Including nearly all of the flagging, metadata, and options you'd expect from a proper Dolby encoder.
It can even indicate if an HDCD/Pacific Microsonics ADC was used? I've never actually tested to see what this does, I just tried with 44/16 WAV from an HDCD with Peak Extend using both the "Standard" and "HDCD" ADC options, and the output seems to be identical. Oh well.
Just about the only thing it cannot do is export the kind of hybrid DD/DD+ stream you'd find on a Blu-ray disc - 5.1 DD with an additional 2 channels encoded as DD+.
Audition 2015.2 didn't cost any more than Audition does today. The only reason Audition can't do this anymore is Adobe presumably not wanting to pay for this license any longer. Luckily for me, it will continue to work as long as I don't uninstall it.
Granted Audition does not support creating a 7.1 Multitrack session and maxes out at 5.1, you can open a 7.1 WAV (or FLAC, or WavPack with a plug-in) and export to 7.1 channel Dolby Digital Plus - provided you remember to swap the SL/SR and RL/RR channels, either when making the WAV (less hassle IMO) or within Audition itself. For whatever reason, they get mapped in reverse vs. what you'd expect from the typical WAV channel mask when Audition encodes E-AC-3, so you have to swap them yourself first to correct for it.
It works very well and also activates enhanced coupling for DD+ bitrates below 48 kbps/ch.
