I signed up for the free first month trial of Qobuz Studio since the price of $14.99 a month reeled me in. This is my first use of a streaming service. I like it and I think I will keep it. But I'm having some issues with finding the optimal audio output to set in Qobuz. I am only going to use this for listening from my desktop PC to home stereo, no plans to try to take advantage of streaming on my Android phone since I am on a very limited data plan to save money. I have an Astell&Kern player for listening on the go. Technical info: Windows 10 desktop PC, Qobuz app, and my primary DAC is a Rega DAC-R which is connected via USB. This is the DAC I use with all PCM files on my hard drive when playing them with JRiver Media Center 24, sending exclusive ASIO to the Rega. I also have an OPPO UDP-205 which I use for playing DSD files since the Rega won't support that format. JRiver is configured with automatic zone switching so it all works very well. The Rega plays up to 192kHz audio and shows the number on the front panel when it switches between 44, 96 and 192, playing all files at their native resolution. I have been told that Wasapi exclusive is the preferred setting in Qobuz and I understand why, that I don't want the stream being modified thru Windows. So that's what I set it to, and Qobuz worked fine with 44 and 96kHz streaming audio on my Rega. When I tried to play 192kHz audio on Qobuz though, it got all slowed down and garbled. I tried a bunch of different output settings. Sending to the Rega with ASIO instead of Wasapi exclusive seems to work but what happens is it sometimes creates a conflict with JRiver even when that app is closed. What happens is JRiver will launch and then Qobuz closes. Once it stabilizes I am able to play 192kHz files thru the Rega. But tell me, is ASIO exclusive?? I want to be sure that the stream is not getting passed thru Windows. Tried playing a YouTube video and it did not interrupt the Qobuz stream. I am not sure if using the ASIO output will be stable though, given the conflict that happens when I open the Qobuz even when JRiver is closed. I am confused by this all. Last night I was listening to 44 and 96kHz on Qobuz thru Wasapi exclusive and sounding great, it only failed when I tried to play 192 audio. Another option I have is to send Qobuz to the OPPO instead of the Rega, but I only have the option of ASIO output to the OPPO. No Wasapi exclusive. And I think my Rega is a better DAC than the OPPO. And lastly, I do have my preferences in the Qobuz app set to max so it should be able to play up to 192kHz audio. Changing buffering settings had no effect. Sorry if my attempts to explain these issues is long and convoluted, I don't have a great grasp of all this tech stuff (have no idea what the difference between ASIO and Wasapi is for example). Any advice and suggestions will be appreciated. I already filed a support request with Qobuz but I figure someone here will be able to help me sort this out. In sum I'd like to be able to select Wasapi exclusive output to Rega if I can get the 192 audio to play right. Otherwise, I can go with ASIO to Rega but it tends to be unstable and prone to conflict with JRiver in that case. Other option is to send it ASIO to the OPPO which will play 192 audio without issues. But tell me, is ASIO an exclusive audio output, so it won't get contaminated by Windows?
