SuperPlayer - The DSP_Engine (CamillaDSP) samplerate switching & ESP32 remote control

[lykkedk]

Hello,

Have you done this right:
IMPORTANT! usr/local/lib/python3.6/site-packages -must be included in /opt/.filetool.lst (indicate when executing the script)

Sincerely

Hey... in post #216 we see that this is okay...

Please provide more info and clearance if you have some Vendeeglobe!

Jesper.

Fra8123 !

The camilladsp & squeezelite are not started before the start script is executed.

Snip from my instructions ::

When edited to your'e setup try to restart the samplerate control setup like this ::

c@TestRig:~$ camilladsp-config.sh -n example

- Setting CamillaDSP configuration to: example

- Creates or updates symbolic links in folder: /home/tc/camilladsp
44100.yml -> example/44100.yml
48000.yml -> example/48000.yml
88200.yml -> example/88200.yml
96000.yml -> example/96000.yml

Sending signal to CamillaDSP to apply configuration: example

Can you perhaps try to execute the script?
First (You must be in /home/tc/camilladsp folder) ::

camilladsp-config.sh example

And paste taht output here...

After that paste output of the start script ::

sudo /usr/local/bin/squeezelite-cdsp.sh start

Jesper.

Squeezelite is already started by pCP.


Once again, I did all the steps in the guide, with the same order. If something is missing in the guide I missed it.


Thank you,
Francesco

 

[lykkedk]

Hey hey hey

I forgot to mention in my guide, that ::

Both squeezelite and CamillaDSP must be started by my script: /opt/camilladsp/cdsp-squeezelite.sh
And: pCP must be configured NOT to start squeezelite on boot.

It's only said in pi r's explanation on the setup... Sry...

Please when you reboot the PI, execute

2 times kill to be sure ::

sudo killall squeezelite
sudo killall squeezelite

Then start the starter-script

sudo /usr/local/bin/squeezelite-cdsp.sh start

If it's working, find in pCP webinterface a place where you disable squeezelite at boot.

Also please look here ::

Jesper.

 

[Fra8123]

Hi Jesper,


Here you are:


tc@piCorePlayer:~$ sudo killall squeezelite
killall: squeezelite: no process killed
tc@piCorePlayer:~$ sudo killall squeezelite
killall: squeezelite: no process killed
tc@piCorePlayer:~$


It does not look to be the right solution


I do not have any skill of software programming. So I can just follow the instruction, but if the instruction skips the step, as a dummy I will skip the step.


I will keep monitoring the guide, hopefully you will have the time to amend the procedure. Hopefully in the near future CamillaDSP can be introduced in pCP as simple plugin. In Moode Player it will be introduced soon .



Thank you so much in any case. Your help is a lot appreciated.

 

[lykkedk]

We try one more...

Never give up

I think this could be the case ::
Try to execute ::

sudo rm /var/run/squeezelite.pid

It look's like the script thinks squeezelite is running, when it's not! Maybe it's the thing...
I think you can start the script after removing this .pid file (if it's exist, i think it does )

Disable the squeezelite at boot... Then reboot the PI. (See attached picture)

sudo filetool.sh -b && reboot

Then goto /home/tc/camilladsp
Execute ::

camilladsp-config.sh example

And ::

sudo /usr/local/bin/squeezelite-cdsp.sh start

Jesper.

 

[Greg Erskine]

To check for pCP squeezelite status:

$ sudo /usr/local/etc/init.d/squeezelite status

To stop pCP squeezelite:

$ sudo /usr/local/etc/init.d/squeezelite stop

In development situations where the squeezelite process and the PID file get out of sync use:

$ sudo /usr/local/etc/init.d/squeezelite force

This should kill the squeezelite process and tidy up the PID files.

Usually you don't need these but sometimes when testing things they are necessary.

Disabling squeezelite and rebooting through the pCP GUI will avoid this situation.

To do a backup and reboot, this is easier:

$ pcp br

 

[lykkedk]

Thank's Greg...

Let's see if Fra8123 figure it out.

Do you btw, working on some kind of camilladsp integration into pCP Greg?

Jesper.

Jesper.

I am keeping an eye on your threads, reading your GitHub instructions, but I think this quote really applies to me:

"Remember it's kind of complicated stuff, and somethings are hard to explain & understand."

I can read as much as I like, but my brain doesn't understand things until I do it hands on. I have been playing with sox to do resampling and apply various filters in the last few weeks, so I think I am making progress. Hopefully the light will switch on and I'll start understand the concept DSP.

Okay... here we go again guy's

Can you look at the example files ?
E.G::

cat /home/tc/camilladsp/44100.yml

At the top look for ::

capture:
type: File
channels: 2
filename: /dev/stdin
format: S32LE
playback:
type: Alsa
channels: 2
device: "hw:0,0"
format: S32LE

We have to make sure your'e dac support S32LE, or S16LE or whatever you use here!
It looks like camilladsp is not started now.
Is it possible that the fault is there?

Jesper.

You say

I can read as much as I like, but my brain doesn't understand things until I do it hands on. I have been playing with sox to do resampling and apply various filters in the last few weeks, so I think I am making progress. Hopefully the light will switch on and I'll start understand the concept DSP.

I see we are much alike... my switch is sometimes slow to engage

Jesper.

 

[lykkedk]

Another thing...

This is much fun to make this Bluetooth LE remote...
It's in real world test phase now

It can do the following now ::

* Play/Pause toggle (Commands send directly to LMS)
* Volume (Either LMS or Camilladsp)
* Display volume on 4 x 7 segment display
* Display "SLEP" -- I now i now SLEP = Sleep on display when ESP32 is in "deep sleep mode"

I dropped using the RPI as Bluetooth reciever, as it's not working very good when placed inside a metal/alu' chassis like in mine DAC... The range goes very low, say less than 2 meters like that... NoGo!... So i used another ESP32 as reciever insted; this reciever sends through usb/serial to the RPI, and is catched by a python script, which also handles the display on the 7 segments led's...

The display is on the reciever part... It's possible to have this on the remote too, but duo to batteriuse we have to make some switch or like to cut off when not used... I find it much better on reciever end, always on and supplied from my PI in my DAC.

Jesper..

Hi Jesper,


I have a khadas tone board, as far as I know it can handle 32 bits. However it was working with the SP ver.1.



If you think it can be helpful for the test, I can try to reinstall pCP one more time, but just if you can amend the guide with the all steps in the correct order, as I did three times so far without any success.


Not sure if it is important, I have a RPI 4 with 2 GB of RAM.


Thank you so much.

Hi...

I will eventually rewrite my "howto", but let's try to start camilladsp on youre setup without anything else ::

sudo squeezelite-cdsp.sh stop

Gives me the output ::

  CamillaDSP is stopped.
  Squeezelite is stopped.
  samplerate-daemon.py is stopped.

Then execute ::

/usr/local/bin/camilladsp /home/tc/camilladsp/44100.yml -vv -p 1234

Gives me the output ::
