Audirvana-PC HDMI Out-Audio Cuts Off on Audir..not on Foobar?

Hi Demian,

Here I am again.
I have purchased Audirvana, however this example is using the Trial on a PC-Windows 10.
PC is connected to Elite Pioneer Receiver SC-97 with HDMI cable out from NVIDIA 1070 card.
Samsung TV connected to Receiver HDMI Main Out.
Debug follows below.
When I play a file on Foobar2000 and then turn the TV the audio momentarily cuts off and then resumes, no problem.
If I play a file on Audirvana [Audio Setting-WASAPI-DAC SC-97] and then turn the TV off, the audio cuts off and it does not return???

The only difference is the software playing the file.<<<<<<

HDMI Inputs do not change in the receiver, as they do for example if I select in Audirvana Audio Settings, Network SC-97. In that case the receiver automatically changes the Input to DMR. The video from PC goes Off and instead the TV shows an SC-97 image of whats playing, etc.

Sorry for typos!
Meant to say when “I TURN OFF” the TV. TV acting as monitor is ON to begin.

The same occurs whether Auto Detect MQA Device is ON or OFF

What would you want to connect your PC to the Pioneer using HDMI in this scenario? It doesn’t make sense. You’re better off using UPnP.

Do not understand your answer. UPNP still needs a physical connection. HDMI connection permits more sample and allows Gapless playback. There is no choice for using Audirvana as different types of music streamer, Using a ethernet cable network connection to receiver defaults the Receiver to DMR mode and Gapless play is no longer possible, etc. etc…The receiver can act as Media Server, which means it is pulling audio from Network but that would require a different player and a elegant and reliable front end to control playback as using the tiny receiver LCD screen is a total pain.

You can use WiFi with the receiver. If your receiver supports WiFi there is no need for physical connection.

The gapless capability depends on the implementation in the Pioneer. If that doesn’t work, that would be the only limitation.

Using a gamer class GPU, even if older generation one, doesn’t make sense if the only purpose is to provide HDMI interface.

Thanks.
I have my reasons for doing it this way, if it works correctly. Yes I know I can go wireless and many other options. You may have your opinions about what is worth it based on the limited info I have provided, that’s ok.
The PC also streams Netflix and Disney through receiver to TV. In case of Audirvana the TV acts as computer monitor. It would be nice to be able to turn it off while maintaining audio and while controlling Audirvana with the iPad remote app…

You are correct to point out that Gapless depends on Receiver implementation, but this receiver supports it depending on what Mode the receiver is in. And what physical connection is used. So quick simple generalizations do not really enrich the discussion.
The fact that Foobar2000 works over HDMI when TV is off and yet Audirvana does not shows that actually the receiver acts differently depending on the software and not its own implementation in this case. Gapless is possible over HDMI while not over ethernet, no matter the software, but that is not the issues under discussion here. Gapless is possible over Toslink, even if using ethernet expanders, but again that’s not the issue in discussion here. Gapless is also possible with Airplay, but again…
