HQPlayer Linux Desktop and HQplayer embedded

[Miska]

If you are not familiar working with Linux command line, for dealing with NAS connection and such it is better to use the HQPlayer OS image which provides web interface for doing it.

 

You scan content to the library on /library page. You can browse and search the library and control playback, discover address of the HQPlayer Embedded, etc using HQPlayer Client (bundled with HQPlayer Desktop and can be installed separately).

Why does Sinc-L work with Roon, but it doesn’t work with USB input (where hqplayer acts as a DAC)? I’m doing PCM 384/32 to PCM 192/24 from USB input.

 

Sinc-M works with the USB input still

[tieuphi2006]

Help me again please!

Hqpe os how to change ip 127.0.0.1 255.0.0.0

Hqpe on Ubuntu it's not sound and I'm not add library.

I'm try google but I can't make its playing.

Thanks miska again!

@Miska do you know why this doesn't work?

Is anyone using Embedded OS image with a recent (T2 chip) Mac ?

 

Nowadays I just boot my MBP from a USB stick et voilà and would like to keep it that way with a new machine. would it work, (provided of course I authorise boot from whatever OS) ?

I think there is not enough buffer to run it smoothly. If such happens, you may need to choose another filter. I've tested poly-sinc-ext2 for example to work fine.

 

[Bayan]

It doesn't seem it's about running smoothly, it doesn't even show as playing or show the bitrates on the general screen in that mode (i've never seen this before). I have 64GB of ram and over 50GB free. I've used other settings where it's too slow to run smoothly and the bitrates still show.

I checked and both CPU and RAM usage are low. There is some kind of bug it seems in Sinc-L when downsampling from USB. Sinc-M and Sinc-S work fine

Is there anyone to help me test HQPDcontrol v4 for Android and iOS?
Someone who uses HQPlayer version 4.

 

Please, write me a private message.
Thanks.

Trying a Fiio K5 Pro and have some dsd issues

1. DSD works from my cubox using NAA image but doesn't work from my HP Prodesk, PCM 768k work fine.  The HP shows Format: SPECIAL but is missing DSD_U32_BE.  I am running Archlinux with the latest kernel.  Anything else I need to load or is it a hardware limitation from the usb ports?

2. Maybe a bug, hqp-control2 localhost --set-invert 1 doesn't seem to work with Embedded version 4.18.0.  Also is dsd wavpack support still on your todo list?

3. I am trying to maximize efficiency since I have a slow i5 cpu and the Fiio K5 Pro doesn't seem to do 48k dsd, it appears to work but plays static. I understand this is common, but I will email the company about a firmware update.  On the plus side it seems to mute between sample rate changes, etc.

4. I don't believe the Fiio runs in dsd bypass mode so would PCM 768 or SDM 256 be the best choice for the AKM 4493 not running in bypass mode?  I think someone said the SDM 256 measures better than 512 for the AK4493.

@Miska Hi Miska, I have experimental sets of convolution in Matrix and Delete does not work (4.18.01) : even after a restart they are still listed

[tieuphi2006]

Embedded license key is hardware locked, while Desktop one is not..

I have been the same problems and hqpe off after 30 minutes. Why I'm adding key.

5. Another addition to my above post, @miska, if hqplayer embedded are paused and I try to ff or rewind both versions become non responsive.  To pause, I tried hqp-control2 with embedd and the mouse with desktop.

Someone by here has experience with this Linux version for audiophiles?

On HQPlayer OS, there's an option in HQPlayer web interface to add a network share that will automatically get mounted on each reboot.

Which Linux version are you using? This sounds like the kernel you are using doesn't support FiiO.

It should work, how did you verify it?

Yes, it is very common, but luckily most poly-sinc filters can convert between rate families, so you can easily stick to 44.1k DSD without massive increase in CPU load.

If it is not in bypass mode, it is better to run it at 705.6/768k PCM. And that will save you also a lot of CPU time.

It likely stops with an error, you could check the log file if there are some errors. Amount of RAM doesn't matter here, HQPlayer Embedded doesn't use a lot of memory.

Fixed now for next release. Seems like I have broken it. Note that the the uploaded filters are not deleted/cleaned up, since that's a bit complicated thing and I don't want to accidentally delete something that shouldn't be deleted. I need to think about how to manage existing filter files, maybe some new page where you can explicitly delete items you don't want and upload custom named ones.

I'm on 5.7.7-arch1-1

 

I think it was status or get-status that shows a 1 in Desktop when inverted but always 0 in Embedded.

 

I think it sounds better in sdm mode, wish there was a way to know if it was working in bypass mode.

 

Also, when sending sdm to sdm the volume is approx 6db louder than pcm to sdm and sdm to pcm.  I have dsd_6db="0" is this normal with sdm to sdm upsampling?

If there's a setting to set the DSD filter corner frequency, it is in bypass mode.

 

But it could be that they are using the DAC chips volume control and that's why it is not in bypass mode.

It should be same as pcm to sdm. And same as if you set dsd_6db="1" for sdm to pcm case. In bypass mode, AKM chips have DSD volume -3.5 dB lower than PCM volume when PCM volume is turned to 0 dBFS. Thus in such case, setting PCM volume to -3.5 dB produces same output level for both.

 

sdm to sdm volume follows your HQPlayer volume setting just like the other cases too.

No dsd options  https://fiio.com/k5pro

They are using a NJW1195 chip for volume after the dac, seems like they are converting sdm to pcm in the xmos chip since sdm output is louder than pcm output for a sdm file.

 

Thanks for the details on sdm vs pcm volume, sdm mode has about a 6db gain vs pcm instead of -3.5db in sdm mode, which was confusing me. 

 

I tried your NAA image on my HP ProDesk, DSD_U32_BE shows up.  Something missing with the Archlinux kernel so not a hardware issue.

 

I am now trying to decide between TPDF at 32 bits or LNS15 at 19 bits at 768k. 

Thanks Miska

That would be really strange with a DAC chip that supports DSD... From the hardware architecture perspective I don't see a reason why they wouldn't run the chip in DSD Direct mode.

Why not LNS15 at 32 bits?
