Beocreate checking sound profile

Hello,

some 2 years ago i have upgraded  a CX50 speaker set with Beocreate. I installed the CX50 DSP profile, and used the system with Volumio since then. Initially there was a lot of discussion on 'pops', but that seemed to be resolved.

However: recently Volumio introduced a version 3. Since then the 'pops' were back.

So, being annoyed on Volumio, I installed HifiBerryOS and initalized with the CX50 settings. All worked well.

But this is where it starts to get confusing.

I did an eeprom check ('dsptoolkit check-eeprom'). The result is: "EEPROM content matches running profile, checksum 40FB6C92F57ABB70177CE053C73F54DC".

I think this is not the correct checksum, 2 years ago there was a different checksum.

So something has changed, but i do not know what. Is this the result of installing HiFiberrOS? Or am i doing something wrong?

Regards, Eric

  2 Years ago, you might have used an older version of the DSP profile. This checksum is correct, it's the current DSP profile:

  Thank you for the good support.

  That is good news. So actually switching over also caused an update of my speakers. Nice!

  Nevertheless 2 more questions, if you don't mind, for my proper understanding:

  • is there no longer a dedicated profile for the CX50 speakers?
  • is the new profile now stored in the eeprom? In other words: if i use the speakers in an other application the new profile is still active.

  Best regards,

  eric

  The DSP profile only defined the general program that runs on the DSP. The different models are just implemented by different filter settings. If you want to use it without HiFiBerryOS, you need to store these settings in the EEPROM. This can be done in the DSP settings.

  OK, but then I need a little help from you:

  In HiFiberryOS storage of settings is done by navigating to >SOUND>DSP Programs 

  And then simply click on "STORE SOUND ADJUSTMENTS...

  Ïf I want to use the profile with a third party application I must uncheck the option "Mute Unknown Programs"

  Correct?

  Yes

  No, this only impacts HiFiBerryOS, you can simply ignore this.
