Exposing app as an audio device

[johnfoxii]

Sorry if this is redundant.
I was thinking to allow the app to be selected as an audio output device in windows.
Maybe this would be in the Windows UWP.

Nice idea! It will create new possibilities. I'm thinking on configuring (in the 'App volume and device preferences' widget) which application streams to DAS. What were you thinking on?

I don't know what's the best way to do it. You probably have to write a driver. Do you know how to do it?

I could not write it but I could take on the research and get the right parts collected. I have VS2017 and a google dev account. Lets see if and what I can put together.
Question, do you think there is something to be done with the buffering delay. If you need to have someone run the code feeing it different settings to find the right combo. I would be happy to try.
Thanks

Nice! Let me know.

See this issue for all the things we tried with latency (if that's what you mean). For me it's < 2.5 seconds with wav 24 bit as stream format. How is the delay for you?

Working - it's possible to send sound from a local application (foobar2000) to a Chromecast Audio device.
However (besides the delay)

1. the sound is quite muffled, undistinct (no exaggeration);
2. at times, it's not possible to select the device: it's necessary to restart.

For me the audio quality is a lot better when I plug in headphones (and stream with the headphones as the recording source). The application doesn't change the audio before streaming.

2. at times, it's not possible to select the device: it's necessary to restart.

Doesn't the device show up, or doesn't it start streaming?

Is it Sam? No matter what the setting is set in the app I have a delay of about 17 seconds starting or stopping. using the casting built into youtube music or spotify I sometimes notice a 1 or 2 second delay. Tracing the cast in YouTubeMusic I see it using Windows Media Foundation I cloned your code. a quick look i didn't see these libraries used but i only had a minute more soon

< 2.5 seconds is the delay between the audio on the desktop and the audio on the speakers.
17 seconds is way too much. Can you post the log, then I can have a look.

Great app, but I'm having a delay of 10-12 seconds. Seems long?

... never mind. Changed to WAV, it dropped down to about 1-1.5 seconds.

Hi! I understand that redirecting shouldn't affect the sound, but it does - don't imagine why. It's not related to the use of either speakers or phones. Devices always show up; at times they just don't turn green even after a while.

[SamDel]

I have no clue why the sound quality is so poor.

When you post the log I can have a look why the device doesn't turn green!
