jabbr Posted June 19, 2018 Share Posted June 19, 2018 The RPi 3 B+ over 802.11ac does DSD256 (at least) with USB2 out to DAC and sounds great. Custom room treatments for headphone users. Link to comment

Yes, but I'm really busy on other things right now. They should test and inspect it on their side. They can ask me if they have something in mind concerning networkaudiod binary.

asdf1000 Posted June 20, 2018 Share Posted June 20, 2018 Hi Jussi, it seems that the NAA 'next track' issue on USBridge is fixed after going in a big circle. I was asked to change a file via SSH in May but after now being asked to change back to the original, the NAA and 'next track' issue is fixed. I see NAA on USBridge is loading CPU at ~30% with DSD512. Is that normal or higher than normal? Link to comment

Of course depends on the CPU in question. But sounds fairly normal for a small ARM CPU. If that's a quad-core (looks like it), in usual top-figures it means 1/3rd of one core, all cores fully loaded would be 400%. Load split 23/13 seems reasonable too, the other two cores are mostly idling. For fun, you can check how interrupt affinity looks like with "cat /proc/interrupts" where it shows how interrupts are distributed among the cores. You may have a challenge if all interrupts go to single core. asdf1000 1 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment
nicoff Posted June 25, 2018 Share Posted June 25, 2018 I am trying out HQPlayer. My intention is to be able to upconvert my files to DSD512. I am looking for ideas as to what NAA I can use to make this happen. My current set up: iMac (running Roon Core) NAA (raspberry Pi3 with Digi+ Hat) Oppo 205 (Roon Ready) I understand that the Rpi3-Digi Pro combo has limited output. Someone suggested that I consider another NAA like the microRendu, Allo USBridge, etc. I realize that I might have to purchase a different DAC (like the T+A DAC8 DSD) since the Oppo 205 might not be able to do DSD512). I read elsewhere in CA that folks are building their our servers that can run Roon Core and HQPlayer and can do all the upconversions. I would appreciate your comments. Thanks! Link to comment
firedog Posted June 25, 2018 Share Posted June 25, 2018 The mRendu or Allo would both be good solutions. As far as a DAC, there are lots of solutions, some of which are quite good, that can do DSD 512 - and some of them are less expensive than the DAC8. The DAC 8 so far doesn’t have the USB drivers to work with a Linux source like the mRendu or Allo or Roon Core if you use Roon OS,. You can also build your own server or have a prebuilt one delivered. You need to decide if you want to go with the direct to DAC route or via a device like the mRendu or Allo.

Miska Posted June 25, 2018 Share Posted June 25, 2018 Note that T+A DAC8 DSD is a really great DAC, but at the moment DSD512 with it works only on Windows. So those Linux-based NAAs are not suitable for it. So if you want to use DAC8 DSD, I'd recommend to just connect it directly to the computer where HQPlayer is running and that's it (this is what I do).

But apparently a lot of Linux-based streamers/renderers do not have a properly working Udev and with those people have not been able to hot-plug our ISO REGEN. Recognition of the hub (the ISO REGEN) only occurs if it is attached and powered on before the Linux device boots up. Once the hub is seen people can plug/unplug the DAC on the downstream side all they want and the DAC will be seen. I'm just reporting based on the support we provide to hundreds of users...

Miska Posted June 27, 2018 Share Posted June 27, 2018 lsusb shouldn't affect it, it is just walking sysfs... kernel deals with it, and depending on device udev reacts to it. You can nicely see the kernel activity by running "dmesg | tail -n 15", then unplug and replug and then run it again and you should see kernel messages appearing about the event.

nicoff Posted June 29, 2018 Share Posted June 29, 2018 While waiting for my desktop windows computer to arrive, I downloaded HQPlayer for iMac just to try it out with Roon. While I was able to get it to connect to Roon and play music, I have not been able to connect HQPlayer to my Rpi-Digi Pro combo. I learned that I was missing the NAA file for my dietpi. But even after installing the file, HQPlayer does not find the NAA. At the moment, HQPlayer while it is still being recognized by Roon endpoint, it will not play. I believe that the trial version of HQPlayer got corrupted somehow. But if I try to delete from the iMac and download a new trial version, the download will not open. Any suggestions? Note: I will be buying a windows version of HQPlayer once my new computer arrives. But meanwhile I would like to play a little with HQPlayer and get familiar with it. Link to comment
