Hello—I got NAA configured in HQ Player and on the iFi Zen Stream. That all worked very smoothly. When I went to play my first track, there was terrible static for a few seconds (mostly in the left channel) and then the music came in, overlaid with distortion/static.
I restarted HQ Player, iFi, and Roon. After this, there was no sound output whatsoever.
I am attaching a few screenshots. Thanks in advance!
I was lately using Roon / HQPlayer on a Mac Mini M1 directly connected to a Holo Audio Spring 3 KTE DAC and I had no issues changing from HQPlayer to Roon back and forth playing the same tracks.
Now enabling a second setup at my bedside with Ifi Zen Stream connected to either some Topping DX5 or Hifiman EF400 DAC by USB I am finding out that HQPlayer is locking my Ifi Zen Stream NAA so I am not able to change back to Roon without disconnecting from HQPlayer for example by shutting down the entire HQPlayer app.
Any idea how I can either
a.) seamlessly do what I described without the locking issue
b) remotely unlock my Zen Stream from HQPLAYER and lock it back? HQPDControl app on IOS for example doesn’t offer that option to change or disable the HQPLAYER NAA source
Answer is easy.
For the same reason as trying different filters, I.e for the sake of different flavors.
Straight Roon is NOS and HQPlayer is OS, very simple and it’s working like a charm once both services are running on the same server and DAC is connected.
Maybe I am a bit spoiled in that regards now
Yep, actually there’s no reason for using straight Roon if having a set of favorite filters in HQPlayer.
I was just used to that freedom but I understand that there are limits due to the nature of allocating exclusive USB devices.
Seems though that this allocation is handled differently if DAC is connected directly to the HQPlayer-/Roon-Server than in the case of Zen Stream to a remote NAA/Roon Endpoint.
Yep, seems current Mac OS and Roon / HQPlayer with some Holo Audio Titanis USB module connected are more flexible here.
The requirement of switching between NOS and OS with one button is though very common and can be found on most R2R DACs like also my currently demoed EF400.
Of course I prefer to use HQPLAYER for performing the OS though and as Roon Remote app is my primary remote frontend in my bedroom the zone switching function is like the simple software pendant to such a DAC physical hardware switch
In worst case, on macOS you just end up with CoreAudio doing rate conversion and mixing. But on macOS (and Windows), most important thing is to check that your DAC is not set as default audio output device for the OS.
In typical case on local DAC connection on macOS you would be doing DSD output through DoP. If that is working, you can be pretty sure CoreAudio is not doing anything.
