No sound with 2-way-eq.dspproj

I've just connected my BeoCreate board to a single speaker for the first time, and I am not getting sound out of the system, but I think I should.

A speaker is connected to Ch1. The speaker is known to be working and emits a very faint hiss, so I think the connection is ok.

The hifiberry-dac overlay is loaded:

dtoverlay=hifiberry-dac

Alsa shows the expected device:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

The DSP gateway is running:

$ ps xa | grep beocreate
  547 ?        Ssl    0:00 /usr/local/bin/beocreate-tcp

SigmaStudio is running 2-way-eq.dspproj and shows "Active: Downloaded"

I've removed the Mute jumper:

I can't think of anything else - what should I try next?

  Hi Lars,

  starting with your own project as the first step isn't really recommended. A lot can go wrong with SigmaStudio. A single incorrect setting of a register can break the DSP flow. Did you test before to upload a program using the Beocreate software?

  Best regards,

  I was afraid you'd say that.

  So I installed the BeoCreate software and went through all the steps and set up a basic fullrange speaker.

  Still no sound out of the amplifier. I can play through HDMI, if I want (aplay -D "plughw:CARD=ALSA,DEV=1" etc.).

  I've ordered a new Raspberry Pi - the current one has a broken wifi module. Better to check that first. If it then still doesn't work, I'll come back here.

  The new Raspberry Pi came in and I tried it with that. Still no sound.

  I'm using a 24V power supply.

  What should I try next? Or should I send the board in for a replacement?

  I tried a 12V power supply - no sound either.

  Also, I just saw you have conflicting information regarding power supply voltages:

  • most pages seem to say 12-24V, like this one: https://www.hifiberry.com/shop/beocreate/beocreate-4-channel-amplifier/
  • this says 12-20V: https://www.hifiberry.com/beocreate/beocreate-doc/beocreate-hardware-documentation/

  Also, I think it would be helpful if the documentation contained information about the polarity of the power supply (something like: + is on the inner side of the barrel connector - or even a picture)

  Hi,

   

  while the board works up to 24V, we recommend up to 20V as with higher operating voltages only heat will increase. There might be a hardware problem in you case. I'll open a ticket for this and we'll discuss the next steps by mail.

  Best regards,
  Daniel
