Title: Video with DTS Audio
Post by: karmat63 on January 28, 2014, 06:33:16 pm

Hi,
after upgrading to 19.0.108 build, the MC can't play film with DTS (DTS-HD) audio through ASIO. No problem with Wasapi or direct audio.
The audio card is an Asus essence ST, linked to an old (but good) Onkio Integra multich. amp via S/PDIF. In audio options I've set only S/PDIF bitstream and nothing else.
No problem with Asio in stereo configuration with some DSP filter (analog output to a tube preamplifier)...

Any idea?

Maybe you'll find something here:

Thanks for your answer, but DSD works (bitstreaming over S/PDIF at 176400).
There's just a problem with DTS if I set ASIO (everything is fine with Wasapi),
It's only a curiosity, more than else, as Wasapi output is perfectly adequate...

I'm not sure ASIO actually supports bitstreaming of DTS. Did this work before?

I'm pretty sure it did...
But, before downloading the new MC build, I swapped the Unisonar drivers for the Essence ST with the original drivers provided by Asus on their site (the Unisonar drivers were somewhat problematic when I changed settings in JRiver switching beetween different "zone", e.g. MCH and stereo settings).
I'm wondering if the Asus drivers stopped DTS from working in ASIO... Don't know, Just a possibility...

Regarding the drivers, it's possible. DTS is probably the least widely supported digital format. I can't find a single video player on my android phone that supports DTS audio. Some used to support it, but they all removed DTS support in the last 6 months or so. I suspect that licensing issues are at play.
