Title: Feature request: Audio input from stream with interface to select audio device
Post by: lucretius on April 27, 2019, 03:55:09 pm

I'd like to be able to route sound to Media Center from other players via a virtual cable.  I realize there exists the "J River Media Center 25" ASIO driver but this has limited utility for me. Also, Media Center would need an interface to select the input device. Thanks.

Could you describe the problem you're trying to solve?

Let's say, for example, that I use Roon software but would like to route that audio through Media Center so I can stream it to a DNLA/UPnP renderer.

We support input to Media Center through various means, through a WDM driver, through an ASIO driver, or through WASAPI Loopback. But what is not supported is streaming Live input to DLNA, Sorry.

As far as supporting input to Media Center, through the various drivers:

I have tried the "J River Media Center 25" ASIO -- Is that the ASIO driver you are referring to?   The one program I tried with it had a problem changing sample rates.  If possible, I'd rather use ASIO4ALL.

As for the WASAPI and the WDM drivers -- where do I find and install those (especially the WASAPI one)? Also, would it be possible to use "Virtual Audio Cable", which is a WASAPI driver.

Thanks.

It's always good to try a search.

ASIO4All is not recommended.  It's just Kernel Streaming.

Thanks.  I tried the WDM driver.  It worked a little better than the ASIO driver but still there was a significant lag when changing sample rates (and sometimes noise).  OTH, the ASIO driver would often hang on sample rate changes. Any suggestions? 

Why not build in the facility to use third party input device drivers? Then I could route the input line from my DAC through Media Center. Also, I could use a virtual audio cable such as https://vac.muzychenko.net/en/ or https://www.vb-audio.com/Cable/.  Both of these work wonderfully with a host of programs.

I use ASIO4ALL with Sound Forge and it works really well.

Except it's not true ASIO, it's a wrapper for kernel streaming which is a legacy Windows component that was succeeded with WASAPI. Kernel streaming likely won't remain in Windows forever, and it's likely Microsoft will remove it at some point in the future.

I see. Thanks for explaining.
