I haven't come across a thread focused specifically on feeding a microRendu with a signal from HQPlayer, so thought I'd start one (please let me know if there is one already - did a search, couldn't find one). I've run into a problem that I'm hoping someone can help me with. As I've mentioned in another thread, I’ve been playing around with the following setup: Roon -> HQPlayer -> microRendu -> iFi Nano DSD Most of my early listening was without using HQP’s filters or modulators and sending out ‘raw’ 16/44.1, just to get everything working properly. I had absolutely no problems, and everything worked perfectly. I then started applying some PCM to DSD conversion: I started with poly-sinc-2s and ASDM7 outputting 11.2896 MHz. This worked perfectly. I then changed ASDM7 to DSD7 256+fs. This sounded a bit better to me. Again, everything worked perfectly. I then changed poly-sinc-2s to poly-sinc. It took about 30 secs for playback to begin (my music server just has a lowly i3 CPU), but when it did, the SQ was transformed. Now it was very, very good! And this is where things started to go wrong. At the end of the track, the playback simply stopped. And I've not been able to get anything to work since: I closed Roon and tried to play directly from HQP – nothing worked. I closed HQP and restarted. I got the 'Failed to open audio device' error message. I started Roon and selected RoonReady in the Audio App Switcher in microRendu. RoonReady worked fine. I uninstalled and reinstalled HQP, and reselected NAA in the Audio App Switcher in microRendu. I still get the 'Failed to open audio device' error message. I have a feeling that the audio device (in my case, the iFi) is being hogged somewhere, but have no idea where or by what. Any ideas or thoughts would be most welcome. Cheers, Mani.
Hi everyone For a while, I planned on building a single audio computer ala CAPS. Then I posted a thread and Jud commented on some of points that got me to rethink my whole strategy. He basically in a few sentences got me to understand the concept of the player / NAA. But it also raised many questions for me. I guess the player / NAA model I am most familar with is HQ Player. Let's start with my questions on that. Can the NAA and the main PC run on different OS? One being e.g. Windows, the other Linux. I plan to use a Hardkernel Odroid as the NAA. Otherwise it would need to be a more expensive x64 based solution If I understand correctly, the whole player / NAA concept is meant to separate the noisy decoding process away from feeding the DAC with a clean signal. The way I understand it, it would work because the connection runs over network, which would serve as block as no electrical signal gets transmitted unlike with USB. My thoughts therefore are that any tweaking (LPSU, minimize activity on the NAA, USB filters etc) should be concentrating around the NAA. The PC could be a plan standard box. Or am I wrong and things like AO optimizer, LPSU etc help as well when you apply them on the player? On the website, I can find the Player package, but where is the NAA package and what are the minimum requirements? That said, is there other software that has this NAA architecture? I believe JPLAY does allow for this too? But what else? Thanks for your time!
