“The USB interface should be both input and output just like on Pro.”

 

So I misunderstood this part. I thought it could somehow be input output at the same time LOL. 

 

Yes, I meant that USB input is bidirectional in both cases. In CC Multichannel mode both optical and coaxial digital inputs are mapped to USB input channels. With Pro additionally the analog input and AES input are also mapped to USB input channels. Likewise DAC and the digital outputs are mapped to USB output channels.

 

The whole show runs always at one single rate. ADI-2 has flexible clocking, so it can be correctly slaved to digital input clocks when those are used.

Nice. Since the ADI-2 DAC and Pro are such great value (great performance at great price), pairing a DAC + Pro isn't as ludicrous as it probably looks... but specifically because I want to run different sources and different sample rates through HQPe, with auto rate switching.

 

It looks a little crazy but I'm actually thinking about it.... the decision is helped a lot by the very good prices of each.. and I do use non-Roon and non-UPnP sources a lot for music listening.

 

I can feed an AES3 source and digital coax source and TOSlink source into ADI-2 Pro... feed that into HQPe... send over the network to NAA... into ADI-2 DAC.

 

Is that how it would work?

 

Which input do you select in HQPE 'input' page to have auto rate switching working?

Yes, with or without NAA.

There's an example config file included with HQPE for RME devices with analog and digital inputs preconfigured. But you need to manually edit it to correct the device id's (simple search-and-replace). This is because RME devices include serial number as hexadecimal in the device name. This behavior is really handy though, when you have multiple such devices connected simultaneously. Otherwise it would be hard to distinguish between the devices and possibly inconsistent across reboots.

I'm traveling with limited internet connectivity and just a laptop. So the amount of testing I can do on the move is quite limited.

Hi there - quick question from a computer novice (who loves hqplayer and Roon) - I have been searching the forum and gotten a bunch great answers but was hoping someone might help we with a simple (probably stupid) question:

 

If I get a intel nuc such NUC8i7BEH with a m.2 ssd and 8-16 go ram, can I just plug an Ethernet cable and a  usb stick containing the hqplayer OS (i.e. 4.11.1) and it’ll boot into hqplayer embedded - then I configure using a web bowser and connect it to my Roon core?

 

in other words - do I need to do anything else to the NUC to get it working with hqplayer?

 

thanks in advance!

 

cheers

I'm pretty sure I know the answer I'll get but I'll ask anyway.

 

Has anyone ever installed HQPlayer embedded on a Synology NAS?

I am having an issue after installing the latest version of embedded. I am using custom image and header. When I issue the 'hqplayerd' command to set username and password, I get this, which just hangs:

Fixed my issue with installing embedded with CUDA support. Apparently order of install operations matters. This time I completely installed embedded and made sure it was running (CUDA offload was not working). I then installed the latest Nvidia driver files and CUDA offloading came alive. Everything is working great now. Here is CUDA working:

In many cases, that's all you need. However, using HQPlayer Client to figure out IP address of HQPlayer Embedded may be useful (depending on your network infra). If you keep booting up from USB memory stick, you don't need SSD at all. And 8 GB of RAM should be more than enough.

Exactly what I wanted to know!

 

Many thanks for an excellent product . .

I bought HQPlayer embedded for my SonicTransporter from SGC. After some testing I found it always stoped after a while. So I gave it up more or less. 

 

As some new releases for desktop (version 4) just came out, I checked my embedded version. 

 

I then noticed I still was on trail.

Somehow along the way during August 2018 and now, the license has been wiped out. 

 

Luckily I found the license file and was able to load it again. 

 

So hopefully HQPlayer Embedded will work for me again. 

(Not tested yet)

 

I’m writing this, so if anyone else had a problem with SonicTransporter and the HQPlayer Embedded, it’s good to check if your license is still properly installed 😀

 

 

Dear R1200CL,

I have had exactly the same problems, with an HQPe version that either reverted to "Trial" or was always that way but I never noticed.  Questions: 1) what was the name of the license key file that you found that worked and 2) can I use a license key file that came with the Sonictransporter when I bought it about a year ago if I've already updated HQPe to Version 4.11.1 (my current "Trial" version) using "Software Update" within the Sonicorbiter?  I am assuming (perhaps incorrectly) that you didn't have to pay to upgrade to HQPe Ver.4 since this is an Embedded version.

Any step-by-step help in getting everything back to normal here would be hugely appreciated!

Thanks

Geoff

I'm sorry I should have asked first, HQPE is running on HQP OS correct? (Miska's image), not Ubuntu, AL or other distro.  so is the NAA correct?

Yes Miska's image.NAA on intel nuc windows 10.Works fine with desktop.

I can't imagine what would cause the screen to... continuously move??

 

Have you tried connecting the Embedded server directly to the DAC first?

[craighartley]

I'm only just beginning to experiment with Embedded, although I've used Desktop for a long time. Can someone explain why CUDA offload is not available with the bootable image version? Thanks.

Actually, it's possible to use Cuda (and change the Multicore setting) with Embedded, even though the options are not available in the web interface. You have to go under the hood and edit the (plain text, xml) config file.

Thank you. So how do I go about doing that? Is there somewhere I can look up how to do it?

I don't know how comfortable you are with Linux and the command line, but I just happened to be having this conversation last night. It goes on for a few posts.

 

 

[k6davis]

Oh!! And Embedded + Cuda only works with Ubuntu Server. It won't work with HQP OS or the other Linux variants.
