Hello, I received my DSP board.

After assembling DSP board on Raspberry Pi4 with DAC2 HD and fully reinstalling latest HiFiBerry OS from the site there are no DSP menu available in hifiberry os web panel.

DAC2 HD with DSP board plugged sounds normally but no DSP menu and no sound effects are available.

After second reinstalling OS and reassembling DSP board (unplug from DAC and plug again) sounds only a squeaks. DAC2 HD without DSP board sounds normally.

Please clarify how I can resolve this issue.

  It might not be plugged correctly. Can you post a picture?

  Even through it probably won't change anything, try upgrading to the latest experimental release using
  
  /opt/hifiberry/bin/upgrade --experimental

  Thanks, correct command is /opt/hifiberry/bin/update --experimental
  Upgraded, but no effect
  
  

  
  
  
  When DSP board plugged in I hear only noise (squeaks), please listen

  Ok, I had expected this as nothing had been changed. But sometimes there are miracles ;-)
  
  Let's try to find out why the DSP detection doesn't work. Please run
  
  dsptoolkit read-reg 0xf000
  
  and post the output

  
  BTW: Don't share any recordings, they don't help us debugging this.

  Ok, looks like the DSP detection is still buggy :(
  
  You can try the following workaround:
  
  touch /etc/hifiberry/dsp.feature
  /opt/hifiberry/bin/reconfigure-players
  
  Then check what DSP profiles are listed

  Now DSP settings available. But I am still getting noise instead sound
  
  
  
  Also, sometimes noise sounding already at once when I plugging in ac power
  But sometimes noise sounding only when I am trying to play music

  Problem is that the DSP isn't detected correctly and therefore, the DSP display isn't shown. We have to implement a bug fix for this. We'll look into this next week.

  @HifiBerryTeam: addon information 

  i can confirm the 'no-detection-problem' in the setups
  Rapsi4 - DAC2HD + DSP Addon -> Board not detected 
  Rapsi3 - Amp100 + DSP Addon -> Board not detected 

  both setups freshly installed with latest software version yesterday 29.05.

  Ok, we need a bit of help here as the DSP seems to behave a bit differently in different setups :(

  Can you please both post the output of the following commands:
  
  dsptoolkit read-reg 0xf000
  dsptoolkit read-reg 0xc000

  I think I found and fixed a bug. Try the latest release
  
  /opt/hifiberry/bin/update --experimental

  Did you update the DSP profile? What profile did you install?

  Maybe it's DSP board or DAC2 HD hardware issue

  Yes, DSP profile was not installed. Now it's playing as expected.
  Thank you!

  Hi HifiBerry team!

  on sunday i freshly installed hifiberry os version 2021 04 08   (via https://github.com/hifiberry/hifiberry-os/releases)
  with this both setups are detecting the DSP addon board correctly and played (with DSP Version 11)
  only thing: max volume is ... half of what it should be

  Rapsi4 - DAC2HD + DSP Addon 
  Rapsi3 - Amp100 + DSP Addon 

  i further updated the DSP Profile to version 13 - again playing well - but still the volume is limited

  next step - i will try to update to latest experimental version

  Thomas Fessl May 31, 2021 17:22

  upgraded hifiberry os to 

  latest experimental version 2021 05 31 + DSP V13

  and now playing totally well now! max volume now as expected! (more than twice the volume compared to before)
  
  

  THANK YOU!

  additional info:
  the (not) max volume problem only existed on Raspi3 + Amp100 + DSPAddon

  Raspi 4 + DAC2HD + DSP Addon -> now also on 2021 05 31 experimental + DSP V13 plays fine
  (but no change in max vol - in other words: max vol was good before upgrade to experimental; namely hifiberry os 2021 04 08)

  kind regards thomas

  I have bought Digi 2 Pro plus DSP-Module. Wanted to try at first on hifiberryos but could not get it to run. It took

  me several hours till i found this link: Updated DAC + DSP profile available 

  After updating, hifiberryos finally showed up. I chose at first a radio station, but from speakers came only noise.

  Under "Sound --> DSP Programs" i could see "DAC+DSP universal" was installed but "DSP add-on" was available.

  After i installed the newest version, Version 11 and Version 13 were available, i got it finally.

  Subsribed to Blog Post after that.

  After rebooting hifiberryos is no longer reachable. Over SSH i can talk to it. Dont know which profile i have to

  install, dont know how to think about it. 10 hours of fighting, i have enough.

  There's a bug in the latest version, see here for a workaround:

  We're working on this, but this will still need some time.

  Followed instructions:

  1. /bin/dsptoolkit install-profile /opt/beocreate/beo-dsp-programs/dacdsp-13.xml

  2. nano /opt/beocreate/beo-dsp-programs/dsp-addon-96-13.xml

  3. edited "samplerate" to "sampleRate"

  4. installed profile within hifiberry web-gui the profile "DSP add-on version 13"

  5. reboot

  6. Success
