WASAPI and Windows sounds
RoderickGI:
Yeah, I assumed that you had. But sometimes it takes a second or third read to understand all the implications of what is written.
It still doesn't explain why you have no YouTube sound. But an understanding of the audio chain, and correction of settings, will get you well down that path.
BTW, the Audio Path tool may help in diagnosing the problem. If you are playing a YouTube video with MC in Standard View in the background, you should be able to switch to MC and see what is happening in the Audio Path.
If playing a video within MC, you can right click on the video, then select Player > Audio Path for the same display.
Compare the non-working YouTube and the working MC video Audio Path displays. You may see something amiss.

Ah, thanks. I had been wondering about Audio Path; will give it a try (maybe tomorrow).

Just did that; ran it four ways...
1: Realtek HD Audio [WASAPI]... Exclusive Access OFF (no YouTube videos).
2: Realtek HD Audio [WASAPI]... Exclusive Access ON (no YouTube videos).
3: Realtek HD Audio [WASAPI]... Exclusive Access OFF (playing a YouTube video).
4: Realtek HD Audio [WASAPI]... Exclusive Access ON (playing a YouTube video).
I did a screen capture for all four test and compared them to each other.
Only three things changed for all tests...
1: Adjust volume by... +xx DB for small speaker mode.
2: Output... 48kHz, 32bit, 8 channel using WASAPI, (not a direct connection).
3: Output... 48kHz, 32bit, 8 channel using WASAPI, (direct connection)

Hi guys...
Guess what?
I GOT IT WORKING!!! Happy Days.
Jim (on another thread suggested that...

So I was staying away from another install of MC, but after almost giving up I decided what the heck "Let's go for it" & do an install of MC. IT WORKED!!! As soon as I booted up everything was working including JRiver WDM.
Now as soon as I stop MC from playing all my Windows sounds, including YouTube, plays correctly & that is with WASAPI Exclusive Access turned on.
Boy-oh-boy that is really neat. Now those annoying unwanted C-Net videos that keep blasting away whenever I click on an e-mail link are muted as long as MC is playing. THAT is one wonderful benefit of WASAPI Exclusive Access.

This is also now working correctly...

That isn't perfect, as shown by many threads on the topic. The WDM driver has a little bit of lag that prevents very short Windows sounds from playing properly, at least on my system, because by the time MC and my receiver have responded to the sound, it is over. I rarely hear Windows dings on my HTPC, and only if there are no other sounds playing. Direct sounds allows Windows to mix sound sources in real time, but also mucks around with your sound all it likes. If you noticed an improvement in sound quality with WASAPI, you may want to try to stay with it, and use the WDM driver.
You will get sound from YouTube, C-NET and other videos, etc., all processed through MC, so you will have all the control available in MC, when you use the WDM Audio Driver.

Roderick mentions the lag time in WDM; I did see a sizable lag in YouTube videos in synchronization of peoples voice & their lip movement. MC TV however did not have that problem most likely due to the fact the TV is part of MC & hence is before WDM so is synchronized.
Either way it is nice to know everything is working correctly.
I want to give a BIG thanks to all who helped me resolve this sticky problem; I could not have done it without you.
