do you have gapless checked in bubble?  How about transcoding options?

Yes, it is checked in OpenHome configuration page for HQPlayer renderer in Bubbleupnpserver.

I’m using transcoding in Minimserver/MinimStreamer to transcode flac and alac files to wav, same bit depth and sample rate as original

If anyone is willing I'd still appreciate info on how to change the HQPlayer Desktop 3 Windows key conversion *txt. file to *hml. Because this isn't working for me. https://www.signalyst.com/convert-key.html

 

Key conversion form was online for couple of years. And it was eventually taken offline when support for HQPlayer v3 ended in June 2020.

 

Generally I don't answer personal license support requests on forums. These should be handled over email. Most of the time I don't know who is behind a forum nick name.

Thanks for your response.

Cannot get past the awful UI of mconnect to even attempt gapless playback.

I'm with you 100%!

 

I can't wait until @Marcin_gpsreleases his JPLAY for iOS app. It's fantastic.

… still in development? I thought the project was dead. One year, more or less, is gone since you talked about it …

He is on the last hurdle before it's released.

Just fired it up with the latest HQP OS and working great at 384k LNS15. Gonna push it now. 5% CPU util.

 

I have it running with ASMD7 at DSD256 right now. I wasn't able to get any of the *EC filters to work--it starts hiccuping. I am good with it. Great for having such a tiny Pi-sized box that can do what it does for now.

I never have figured out how play playlists in HQPe, although I have no problem doing that with the desktop version.

 

I keep m3u8 playlists in a separate subfolder in my drive mount.  When I scan the library, it appears they are imported. My client, HQPDControl, lists the playlists under the “playlists” tab even though their subfolder doesn’t show in the Dirs list like the other mount subfolders where I keep music files.
 

When I tap on any of the playlists’ “add playlist and play” menu item, HQPDControl says the playlist is queued, but nothing happens.  No track shows as playing and no queue displays.  (With HQP desktop, the playlist loads and plays when selected this way.). See the screenshot, which shows that a playlist has loaded into the queue.

 

I have tried loading playlists manually in the HQPe interface library tab by typing “/smb” or “/smb/HQPlayer playlists” into the “load/save/delete “ dialogue area and then clicking on “load.”  That usually either produces a “fail” error message or causes nothing at all to happen.

 

 I am sure there must be a simple solution to this problem.  What can I do to enable playlist playback?

Paths to the files on the playlist likely point to a different folder root structure than what is seen by your HQPlayer Embedded machine. This means HQPlayer cannot find the files at specified directory path.

This is a screenshot of the file structure of the mounted drive.  How can I get HQPe to recognize the circled directory, which is where the m3u8 files are located?

Playlist file contains list of file references to the tracks. Open your m3u8 playlist file in Notepad and consider the file references listed there from HQPlayer Embedded's perspective. Do those match with the file system view the HQPlayer Embedded machine has?

 

Easiest way is to create your playlists straight in HQPlayer Embedded, instead of importing those from somewhere else.

I assume this is done by using the client?

Yes, that's correct.

 

I'm not sure if HQPDcontrol supports similar functionality at the moment.

Ive been using hqplayer for a while now and I’ve just installed a new cpu.
 

Together with this I’ve performed a clean install of ubuntu 22.04 and hqplayer embedded (hqplayerd_4.32.5-143avx2_amd64). At the moment just using the generic kernel (5.15.0-52-generic). 
 

I think I’ve got all my settings ok…. hqplayerd service is active, but when I try to play music from roon I’m getting a message I haven’t seen before “Discovery request did not have a valid MX header” (see attached image) and no music plays.

 

I’ve checked the hqplayer log and there are no errors or anything weird that I can see… 

 

I’ve also attached a pic of my settings in case I’ve missed something….

 

Any help is appreciated…

@MJ1409can you play using HQPlayer embedded alone?

@stefano_mbp thanks for the suggestion…. Just tried it, unfortunately it doesn’t work.

 

I’ve also tried using jussi’s custom kernel (5.15.71-jl+)….this also did now work

Try for first to simplify your configuration , connect the dac directly to the pc with usb, if it works try using the NAA

HQPlayer 4 Embedded 4.33.0 released!
Control API improvements. Support any picture as cover if specific one is not found. Support for favorites in library. Number of bug fixes. Performance optimizations and new tuning option. FLAC update to support higher sample rates and up to 32-bit word length. CUDA update to support new GPU generation. HQPlayer OS update and optional dynamic hostname service.

 

@Miska That's a lot, thank you very much for the new features. 👍

 

Where can read the tuning options? Can now edit the favorites of Qobus in the HQPClient?

readme.txt has you covered.  But the new parameter is "nblocks" in the "engine" element. Current dynamic value should be fine though, so you shouldn't need to adjust much. If you set any value there, it will override the default dynamic one. Good starting point range is 4..8. Primary driver for the value is amount of CPU cache. If you use GPU offload, you may also want to keep it fairly high.

You will need to wait for new version of Client. But HQPlayer Embedded now supports favorites for the local library with upcoming Client version.

@stefano_mbp thanks for your help….. in The end not sure what it was…. I reinstalled os for both NAA & server with latest hqp versions. All seems well now…. Though I still get that weird message.

I'm very much enjoying the new 4.33.0 release (HQP OS avx2 version on a Ryzen 7 5800X without GPU). 

 

Evidently because of the "performance optimizations" and "HQP OS update", I'm able to use some filters that were just out of reach before. I've done quite a bit of experimentation, so it's hard to know if this release inherently sounds better or if it's due to the new (to me) filter and modulator combos I'm using. But either way, the new release has improved my sound yet again when I was already very happy with it.

 

Thanks Jussi.

@Miska after updating to Embedded 4.33, the DSD rate looks strange. The endpoint is DoP but previously the DSD rate was showing 11.2MHz for DSD256 but this time it shows 705600/1/12. Is that intended? NAA is 4.24 for macOS.

I wanted try embedded on a rpi4 in order to have a low powered, low noise solution. I am thinking about power costs here in the UK where I am. I have a rpi4 with 4gb in a Argon M.2 case which has active cooling. I am only thinking of PCM and not DSD.

 

I think these are still the instructions https://www.signalyst.com/embedded-install.html?. I see Ubuntu has been updated since, so can I use Ubuntu Server 22.04.1 LTS (64-bit)?

 

Are there any instructions to install from the command line?

 

Thanks for any help.

Why not use HQPlayerOS? … just burn it on the sd card and you’re done
