Native DSD bitstreaming

(1/4) > >>

mlknez:
I see that DSD bitstreaming has been added to MC31, but it is only implemented as DoP via WASAPI.  Is there any reason that it cannot be implemented as a native bitstream over WASAPI?  My pre/pro DAC only accepts native dsd over HDMI.  I am sure that it true for many others.  Native DSD bitstream over ASIO works just fine on my external DAC.

Dr.Ames:
Most DACs I know come with their own installable ASIO driver for Windows 10/11, which can be used to configure native bitstreaming directly without any problems - see https://wiki.jriver.com/index.php/DSD.

dtc:
WASAPI does not support the format needed for native DSD. That is why ASIO drivers are supplied by the manufacturers for native DSD support.

HDMI drivers on PCs do not support native DSD. The companies that develop HDMI for PCs are interested in video, not audio. So, audio devices often support native DSD over HDMI but PCs do not. To get native DSD from a PC you need to use usb.

By the way, DSD bitstreaming has been available for a long time on MC. It was one of the early adopters of DSD.

Thanks.  I meant to say DSD bitstreaming over HDMI.  I have been using it over usb via asio for awhile.   I guess i will continue to use my external DAC for all DSD then.

dtc:
I believe that the new bitstreaming option in .10 only applies to audio from video formats, like mka files.  Those are audio only (e.g. Dolby Atmos) with no video, so the new feature is to allow those audio only files to go through the video system and therefore be allowed to bitstream. I do not think it applies to DSD files.

It would be nice for the graphics hardware developers to support DSD over HDMI, but they understandably have no interest in customizing for audio only files.
