sigmatcpserver & dsptoolkit - Beocreate ( low volume / no audio ) [ OSMC & Kodi ]

Hi,

Following my previous post : https://support.hifiberry.com/hc/en-us/community/posts/115003632385/comments/16025647315101, I ended up buying a Beocreate board.

Now I'm trying to make it work.

Working Solution :

https://support.hifiberry.com/hc/en-us/community/posts/16086607877149/comments/16112662593821

Outdated :

I downloaded and install the latest HifiBerry OS, at first the volume was very low, following this topic, I ended up reboot the system and the volume was Ok : https://support.hifiberry.com/hc/en-us/community/posts/360016133998-beocreate-very-quiet-volume

I went to advanced setting to store the profile to board.

As my main usage for the Rpi + Beocreate is to watch videos, I wanted to use the Beocreate with Kodi. Usually and with the AMP2, I'm using LibreElec, but since the system is closed (cannot install packages with apt), I switched to OSMC to install dsptoolkit.

Btw, there is a little missing step during the installation : https://github.com/hifiberry/hifiberry-dsp/issues/58

I set the config-user.txt correctly :

osmc@osmc-Wilbur:~$ cat /boot/config-user.txt
# beocreate
dtoverlay=hifiberry

dtparam=spi=on

Unfortunalty, the sigmatcp service keeped on crahsing :

Jan 14 15:20:46 osmc-Wilbur sigmatcpserver[1115]: ERROR:root:can't create ALSA mixer control DSPVolume (Mixer DSPVolume not found (cards: ['sndrpihifiberry', 'vc4hdmi0', 'vc4hdmi1']))

So I launched it manually :

sudo /usr/local/bin/sigmatcpserver

And send the profile (from https://github.com/hifiberry/create/tree/development/Beocreate2/beo-dsp-programs ) :

osmc@osmc-Wilbur:~/install$ dsptoolkit install-profile beocreate-universal-11.xml
DSP profile beocreate-universal-11.xml installed
osmc@osmc-Wilbur:~/install$ dsptoolkit get-limit
Limit: 1.0000 / 100% / 0db
osmc@osmc-Wilbur:~/install$ dsptoolkit get-volume
Volume: 0.0079 / 30% / -42db
osmc@osmc-Wilbur:~/install$ dsptoolkit get-limit
Limit: 1.0000 / 100% / 0db

So it seems that everything was ok, but I still got no sound.

Even when I change the volume with CLI or with keyboard from kodi.

I also tried with another profile, but the result is the same : https://github.com/hifiberry/hifiberry-dsp/blob/master/sample_files/xml/beocreate-default.xml

Some troubleshoot cmd I found :

If you store settings to the DSP you cannot install the DSP profile again, because this will overwrite the settings you had just stored to the DSP.

Hi,

For now, I just want to make it work as a normal amplifier, no special settings.

With these changes ( https://github.com/hifiberry/hifiberry-dsp/pull/62 ) , I managed to make the dsptoolkit & sigmatcpserver work on OSMC, load beocreate-universal-11.xml, but there is no sound ouput.

Just run HiFiBerryOS and store the setting to the DSP. When the settings are stored on the DSP you don't need dsptoolkit at all to "just run is as a normal amplifier".

However, I'm not sure why you have choosen the Beocreate if you just want to do what the Amp2 already did.

I already did that, but it doesn't work either.

I'm trying to make it work step by step, first as an amplifier then amplifier with digital input ( I didn't had the right digital cable ).

I bought a Beocreate following this advise to have a digital input : https://support.hifiberry.com/hc/en-us/community/posts/115003632385/comments/16025647315101

I made it works with OSMC.

Install the tools
```
bash <(curl https://raw.githubusercontent.com/hifiberry/hifiberry-dsp/master/install-dsptoolkit)
```
sudo nano /boot/config-user.txt
```
dtoverlay=hifiberry-dac
dtparam=spi=on
```
Install the profile from https://github.com/hifiberry/create/tree/development/Beocreate2/beo-dsp-programs
```
dsptoolkit install-profile beocreate-universal-11.xml
```
Set the volume higher :
```
dsptoolkit set-volume 0.3
```
Save the changes :
```
dsptoolkit store
```
Restart if it's not working.

Now waiting for my spdif cable to check the digital input. :-)

Hi (again),

No time to receive the cable, there is another issue happening.

Yesterday, everything was ok, but today as I start the system, there is not sound again.

I check there is no program installed on the board :

So I tried to upload a new one, but there is also an issue :

Any idea ?

This shows that there is a problem with the SPI communication to your board. This is a log from HiFiBerryOS? Try unplugging/replugging the board. You can also try another Pi.

Yes, it is from the HiFiBerryOS. I tried several time to power off / on.

I tried on a Rpi 2 with raspberryos, the result is the same :

vincs@raspberrypi:~/Downloads $ dsptoolkit install-profile beocreate-universal-11.xml
DSP profile beocreate-universal-11.xml installed

In the service log :

Jan 16 15:10:49 raspberrypi sigmatcpserver[1467]: ERROR:root:checksums do not match, aborting

EDIT: After a few, install-profile, reset, save, reboot, ... It's finally working again. Hope it will last.

EDIT-Bis: I just got the cable, and it worked on the first try. :-) Finger crossed that is stay the same.

Hi !

Everything is running fine for a few days, and I'm building a case for the Beocreate.

I'm trying to use the RPI GPIO12 to control a PWM Fan using this script : https://github.com/tedsluis/raspberry-pi-pwm-fan-control/blob/9c2b5ab1ce9ec5b51ec83b8b77345fec82d2d48f/fan_hardware_pwm.py

The config.txt needs to be changed with : dtoverlay=pwm-2chan,pin=12,func=4

But, when I apply this configuration, the sigmatcp services doesn't want to run, here is the log :

The issue is that it seems that the RPI GPIO12 is the only pin left with PWM capabilities.

Any ideas on this one ?

Thanks. :-)

On the Pi (and on other embedded systems), multiple function blocks share resources. I'm not sure, but I remember that that's the case with I2S and PWM. In this case, you can't use the hardware PWM. You need to implement some software PWM that doesn't require the hardware PWM block.
Alternatively you can try the new Pi5 as this uses a completely new IO chip. I'm note sure if they have decoupled I2S and PWM on this one.

Note that we never tested it here, so it's just and idea to help you debugging/fixing it.

Hi,

I'm trying to build an app for remote control of the Beocreate volume, the one included with HifiBerry Os is fine but as I'm using Kodi, I cannot make use of it.

For now, I'm relying on ssh command but it's not very responsive. So I'm wondering :
- Is it possible to pilote sigmatcp server with tcp/http calls ?
- I've seen that the HifiBerry App send and receive command trough websocket, is it something I could install/use on another system ?
- Or even the whole remote application ?
Thanks for your help.

sigmatcpserver is a daemon that receives command on a TCP socket. Check out the source of the dsptoolkit application which is just a client to uses this server. It has a command "set volume" that you can use for this.
