Right, and I'm looking for a way to do this on the HQPe machine.

 

It would take some more work but you can setup a service per room with an different OS user for each, then put the corresponding config file in the user's home directory. This way, based on which service you start you'll get the config you want.

Hi,

finally a Linux driver is available for Merging Hapi. Will it be integral part in the HQPlayer of future releases?

my question as newbie with respect to Linux. What should I try? Linux embedded or Linux desktop? Do I have to install Ubuntu or another Linux OS first?

best regards.

Because it is device specific it is hard to say. But with "arecord -l" you can see available input devices and their names. You can compare this with the current config for USBStreamer and then modify accordingly for some other device. Depending on how the device represents things you may need to change other things either in configuration file, or through ALSA mixer.

 

 

Hi Jussi

 

I have a Bluesound Node 2i for 30 days. Testing AirPlay and Spotify Connect but still have pops with the USBStreamer. So it definitely isn't the source side that's the issue.

 

I have another TOSLink to USB interface that I'm trying to test in place of the USBStreamer and setup as an input with HQPe.

 

I enter "arecord -l" and get this error:

 

root@debiani7:/home/user# arecord -l

bash: arecord: command not found

Ok I used "cat /proc/asound/cards" instead and got this:

 

root@debiani7:/home/user# cat /proc/asound/cards

 0 [USBStreamer    ]: USB-Audio - USBStreamer

                      miniDSP USBStreamer at usb-0000:00:14.0-7, high speed

I got "arecord -l" working too:

So I added this to nano /etc/hqplayer/hqplayerd.xml "engine" section:

 

 <input channels="2" device="hw:CARD=Device,DEV=1" name="USB Sound Device @44.1k" nperiods="4" period_time="100" samplerate="44100"/>

But it won't select in the HQPE input page:

No changes, DoP is enabled for 176.4 and 192 input rates as before.

 

 

 

Hi Jussi,

 

Input of DoP64 failing for recently has been driving me insane (like you listening to sine waves - so we're even! ) because I saw with my own eyes it was working in previous versions- so I just rolled back to 4.7.1

 

And now with 4.7.1 again DoP64 is working fine again - so I haven't gone mad and it's not my source/chain.

 

There is definitely a problem for me with 4.8.0 with DoP64 not working when USBStreamer @ 176 is selected...

Don't ask me what the problem is though lol.

 

 

1854164277_ScreenShot2019-02-05at3_10_18pm.thumb.png.fda90a9af4697a2fe9dada4298bf9cc9.png

 

 

Btw, I just noticed ALSAMIXER looks different for the USBStreamer between HQPe 4.7.1 and 4.8.0. With 4.8 there were two "Mic" inputs showing for USBStreamer. Not there with 4.7.1

 

1905045554_ScreenShot2019-02-05at3_24_21pm.thumb.png.f3b6a069ce2879ebaa6ebc4446cb36c0.png

 

And which clock is supposed to be used - internal or TOSlink? This was also different for me between HQPe 4.7.1 and 4.8.0

 

I noticed "nperiods" is missing in 4.7.1 for USBStream @ 44.1 and others? Anything else different? The additional of Mutec inputs hasn't caused issue?

 

I have to retest all the pops I've been hearing , now with 4.7.1 and Node 2i as source.

 

This discovery makes me feel I'm getting closer to solving the pops issue... maybe not though, so let's see.

I can confirm the Linux driver. Merging is preparing the official notice.

How curious are you?

Mysterious... I have not seen that clock source selection switch before! For inputs it should certainly be set to Toslink clock source. Setting it that way could possibly fix the pops you are hearing, if it was set to internal clock. With inputs the receiving device is clock slave. When you are only sending something out you need to be clock master (internal clock).

 

But these alsamixer differences have nothing to do with HQPlayer Embedded though. Is this from Ubuntu/Debian?

Ok I selected I "IEC958 In" as the capture source...

 

Now there is sound coming through but it's not pleasant. Even if the 16/44.1 music (Airplay) is stopped, there is sound coming through  - like intermittent static...

There's no choice for S/PDIF in? IEC958 is raw mode used for DolbyDigital/DTS.

...because there's no sub-element #1, only #0... DEV=1 is asking for #1.

Ok just spent a good couple of hours, repeating everything to triple check...

 

Sticking with USBstreamer for now - I will worry about the other interface after I solve the USBStreamer riddle.

 

No cables needed to be touched/unplugged for these tests... all done via ssh and Mac control:

 

v4.7.1 - TOSlink clock source:

- DoP64 works 100% fine 

- 44.1 is 100% pop free for the first time

 

v4.7.1 - Internal clock source :

- DoP64 does NOT work

- 44.1 has the 2-3 pops every track like I initially reported

 

v4.8.0 (updated via ssh - no cables in the above touched) - TOSLink clock source:

- DoP64 does NOT work

- 44.1 has the 2-3 pops every track like I initially reported

 

v4.8.0 (updated via ssh - no cables in the above touched) - Internal clock source:

- DoP64 does NOT work

- 44.1 has the 2-3 pops every track like I initially reported

 

Something funky with v4.8.0 for sure...

Does it start working with 4.8.0 if you take off the nperiods parameter from the config? IOW then you'd have the same config and code for both...

 

 

I just deleted nperiods from the v4.8.0 config file

 

DoP64 still doesn't work with TOSlink clock source for v4.8.0

 

Went back to v4.7.1 again with TOSlink clock source and boom, DoP64 works fine again. So easily repeatable. Must be the 6th time (within a couple of hours) i've switch between 4.7.1 and 4.8.0 and reproduced the same issue.

 

Some funky interaction between 4.9.151-jl+_12_amd64.deb kernel update and v4.8.0 HQpe?

No, if 4.7.1 works then it is certainly not due to the kernel.

 

 

Ok. So it's the v4.8.0 update then? 

 

One interesting thing is when I unplug and replug USBStreamer, the clock defaults to "Internal source clock"... even after I was previously on "TOSlink source clock"

 

No wonder I've had pops since December if this is the default...

 

Only today I realised you can switch to "TOSlink clock" via Alsamixer...

You can have HQPlayer reset the value when input is selected, I'll add it to the config file for next release. Add following item to each USBStreamer <input> element:

  

script="amixer -D hw:CARD=USBStreamer sset 'miniDSP Clock Selector Clock Source' 'miniDSP TOSLINK Clock'"

Thanks. We're getting closer to making USBStreamer input bulletproof!
