  1. Hi, looking for a R2R DAC as my next upgrade. I currently have an Auralic Vega which I really love, but getting the upgrade itch. Has anyone had any experience with the Soekris 1541? From reading th description on their website, it sounds like a similar ttechnology to the holo spring. Any feedback would be greatly appreciate! http://www.soekris.dk/dac1541.html

    PCM works in Ropieee and Dietpi. In Dietpi, I can connect either using RoonBridge or NAA. The only software where DSD also works is moode. In Dietpi, the DAC is connect via HDMI and I think DSD only works via i2s. Ropieee connects via i2s, and DSD64 shows up in Roon in yellow which means while the format is supported, additional configuration is needed before it will work. Hope this is helpful - would be great for both PCM and DSD to work in the NAA pi image. Thanks you!

    I also found some postings about this DAC on diyaudio and it looks like the rpi-dac (i2s) driver should be used and dtoverlay=simple-bclk-64fs should be added to /boot/config.txt not sure if this is helpful...

    I think this is the manufacturer website... http://www.suptronics.com/miniPCkits/x4000-software.html I can help to look...if you tell me what to look for...

    Hi, here is the amazon link. I set it up and can confirm DSD works (via i2s) and so it seems like good value. But to my ears, it’s much better to have HQPlayer in the chain and so if a Pi NAA can play to it directly (I tried and it does not) that would be awesome! Thanks. https://www.amazon.com/WINGONEER-WX4000-Multifunction-Expansion-Raspberry/dp/B06XCDGS1B/ref=sr_1_16?ie=UTF8&qid=1513216305&sr=8-16&keywords=Pi+dac

    Hi, just tried it with DietPi and NAA and it works! Although for some reason, I am limited to PCM even though the ess9018 supports DSD...

    Hi, saw an interesting/inexpensive Raspberry Pi DAC on Amazon: the Wingoneer WX4000. Does anyone know if I can use this as an NAA endpoint / DAC and connect directly to my pre-amp? I guess since Pi3 can be used as NAA, I’m really wondering if the Pi3 NAA image has the drivers for the DAC. It looks like it is connected to the Pi3 via HDMI. Thanks!

    That’s actually one of the reasons why I moved HQPlayer to the server. I started using a NUC NAA device (thanks for the x86-64 image) and so it became having 2 pc’s running all day (NAA and dedicated HQPlayer machine) when I only listen perhaps an hour a day. I tried a pi2 to save some power, but that was not powerful enough for DSD256.

    I wrote a very simple PS script to switch to High Performance when HQPlayer uses more than 3% of CPU. It’s not the most elegant thing, but it does the job although it does use up resources by continuous checking of HQPlayer CPU usage. I wonder if HQPlayer can simply change the power profile on its own when it is playing, and then switch back when it is idle. #Power Scheme GUID: 1ca6081e-7f76-46f8-b8e5-92a6bd9800cd (Maximum Battery #Power Scheme GUID: 2ae0e187-676e-4db0-a121-3b7ddeb3c420 (Power Source Opt #Power Scheme GUID: 37aa8291-02f6-4f6c-a377-6047bba97761 (Timers off (Pres #Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e (Balanced) #Power Scheme GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c (High performance #Power Scheme GUID: a1841308-3541-4fab-bc81-f71556f20b4a (Power saver) #Power Scheme GUID: a666c91e-9613-4d84-a48e-2e4b7a016431 (Maximum Performa #Power Scheme GUID: de7ef2ae-119c-458b-a5a3-997c2221e76e (Energy Star) #Power Scheme GUID: e11a5899-9d8e-4ded-8740-628976fc3e63 (Video Playback) $p = '8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c'# To match the CPU usage to for example Process Explorer you need to divide by the number of cores$cpu_cores = (Get-WMIObject Win32_ComputerSystem).NumberOfLogicalProcessorsdo { $currScheme = POWERCFG -GETACTIVESCHEME $c = $currScheme.split() do { # To get the PID of the process (this will give you the first occurrance if multiple matches) $proc_pid = (get-process "*HQPlayer*").Id[0] # This is to find the exact counter path, as you might have multiple processes with the same name $proc_path = ((Get-Counter "\Process(*)\ID Process").CounterSamples | ? {$_.RawValue -eq $proc_pid}).Path # We now get the CPU percentage $prod_percentage_cpu = [Math]::Round(((Get-Counter ($proc_path -replace "\\id process$","\% Processor Time")).CounterSamples.CookedValue) / $cpu_cores) If ($prod_percentage_cpu -gt 3) { PowerCfg -SetActive $p } else { PowerCfg -SetActive $c[3] } start-sleep -s 10 } while ($prod_percentage_cpu -gt 3) }while ($true)

    I was trying to be more green since the server already runs 24/7 and in the past, I also kept the dedicated HQPlayer machine up 24/7. I was doing some googling and it appears with powershell, I can monitor processes and perhaps I can figure how to switch to the performance profile on the fly if the HQPlayer process consumes more than x% of CPU time. i have an Auralic Vega.

    Thanks. Is there another way to solve the issue besides permanently setting it to high performance? I notice when I change to the high performance profile that, at idle, my CPU voltage goes from 0.84V to 1.45V and core speed goes from 2ghz to 3.6ghz. Yes, that’s what high performance means and so the setting is doing what it’s supposed to do, but given I don’t listen to music 24/7, I would like to be energy efficient. Is there a way to change to the high performance profile automatically when HQPlayer is under load? Eg., In my ideal word, I would always leave HQPlayer running (since I control using Roon) and then when I start to play music, it changes to the high performance profile. When I was running HQPlayer in a Windows 10system, I didn’t have the pausing issue even though my profile was not high performance. Is this specific to Server 2016? Thanks, Hammer

    HQPlayer and priority in Windows. Hi, I recall reading on this thread sometime ago that one should not set the priority level for HQPlayer in Windows because the only impact that would have is on the GUI and not the signal processing give HQPlayer manages that internally. I am running HQPlayer on a Server 2016 system with a GTX 1080 for CUDA offload. What I find is that the music will pause every so often, but as soon as I RDP into the system to see what is happening, the music starts up again. Therefore it appears Windows is suspending HQPlayer. The system has 64 GB of RAM, a 16 Core Threadripper, the GTX 1080 and not running anything in the background and so I think it is not a resource issue. Has anyone experience this and if setting priority does not help, are there any workarounds to get HQPlayer “running” all the time? Thanks, Hammer

    That did the trick! Have HQPlayer running on a 16 Core threadripper system and upsampling to DSD256. Noticing that even with 16 physical cores available, only 6 is being used by HQPlayer. Is there a cap on how many it will use?

    Thanks...I'll investigate some more. Looking at task manager, it appears HQPlayer listens to port TCP 4321. I'll check if opening that solves the problem and report back.

    Thanks. Was hoping I won't need to do that for security reasons. This is not a dedicated machine just for audio.
