On the Mac the audio output controls are in "Sound" in the System Preferences, and under "Output" I have selected "Digital Out" of type "Optical digital-out port" and below that it says "Settings for the selected device: The selected device has no output controls". I'm not aware of anywhere on my Mac I have my optical out port configured to support encoded audio, and I'm not exactly sure where I would I see that.

Can you see the Audio menu if you can disable encoded audio output? I fear that your audio output device claims to support encoded audio, which in fact it does not. AC3/DTS should be decoded by VLC and converted to an uncompressed stereo bitstream) and bitstreaming of compressed audio should be left to the end user to optionally enable. If for some reason the VLC team doesn't want to implement the equivalent feature, bitstreaming should definitely default to off on digital audio outs (i.e.

In particular, step 5 there shows how you can tell the PS3 what formats your playback device supports.

A good example of how to do this is what the Sony Playstation 3 does: I'm fine with VLC being able to bitstream audio over digital outputs, but it should not default to this unless there has been some setup done with the user to configure the digital output so VLC knows what formats it can handle. I've also found no way in VLC 3.0 to enable any sort of AC3 or DTS decoder either globally or on a per file basis while I've got my DAC hooked up to the optical digital output of my Mac Mini (which is the way I listen to everything - my DAC goes to a headphone amplifier and a speaker amplifier). In the case of video files with only AC3 or DTS tracks, I cannot use VLC 3.0 for playback and get usable audio, it will only send the raw bitstream out to my DAC which means I can only hear digital noise. VLC 3.0 defaults to playing the AC3 or DTS track, which in the case of my JDS Labs OL DAC means I get to listen to digital static until I manually change to the AAC track.

VLC 3.0 will do that with AAC audio, but interestingly 3.0 no longer defaults to AAC tracks in MP4 files on my Mini if that file has an AC3 or DTS track. In versions of VLC previous to 3.0, VLC will decode the AC3 or DTS bitstream into an uncompressed stereo audio stream and that would get sent to my DAC, and I can hear it properly no problem. This DAC does not have an AC3 or DTS decoder. In my case I have a JDS OL DAC hooked up to my Mac via optical digital output: What it looks like VLC 3.0 is doing is assuming that if you are on at least a Mac Mini and using digital out that whatever you are sending the digital audio to can handle undecoded AC3 (Dolby Digital) or DTS audio bitstreams. I went to submit a bug report for this problem, saw that the VLC site recommends I check the forums first for a similar problem, found your post and here I am. In addition trying to play these files via VLC 3.0 still has no audio. I've checked that movies played via Quicktime player have normal sound. The audio is going out via the digital optical out to a Sonos sound bar/sub/and play 3s for surround, video going to Sony TV via HDMI.
