Media Player Classic unable to play DTS

[Sivar]

Media Player Classic is silent when playing media with DTS or DTS-MA.
I've searched online, but every recent article instructs me to click "Audio Decoder" in Options --> Internal Filters.
I can't! The button is disabled!
I've tried changing my audio renderer in Playback --> Output, but doing so does not enabled the button in question no matter the setting.

How do I enabled DTS playback?

For an unknown reason your internal LAV audio decoder in not OK. It should been the same as LAV video & splitter. Yours is greyed out. THERE you can enable DTS decoding ,AFAIK is enabled by default. I've never experienced that issue. All the time i install MPC-HC DTS playback has no proplem.

He is using external LAV Filters. There should be a configuration shortcut for LAV Audio in your Windows Start menu.

A possible cause of your problem is that you enabled audio bitstreaming. LAV Audio decoder will fail in case the audio renderer does not support it for the format(s) for which you enabled it.

Thank both of you for your help. LAV settings were indeed the culprit. My audio decoder button is still disabled, but DTS now plays.

Future readers with the same problem: DTS audio plays correctly when you ironically uncheck the two DTS bitstreaming checkboxes in LAV Audio setup.

My copy of LAV is part of K-Lite Codec Pack.
If your setup is different, note that you can start the pictured configuration dialog with the following command in PowerShell or the command prompt:
C:\Windows\System32\rundll32.exe "C:\PATH\TO\lavaudio.ax",OpenConfiguration

Thats not very ironic, if your hardware doesn't support DTS bitstreaming, then it will just fail. They are disabled by default, so you must have checked them yourself.
Unless K-Lite ships with such broken default settings.

I may have done so back when I had an Emotiva UMC-1 connected to my PC.
You are right that disabling bitstreaming is not technically ironic. Non-technically, the user is unchecking boxes which mention the features in question, so if they don't stop to think of the meaning of the term "bitstreaming", at first glance I think it seems unexpected.
