Hi
I have a problem with my beocreate amplifier.
In order to make it work I need to reprogram the DSP when I boot the system using the CX50 profile. If not the volume is very low!
Is there a way to save the profile to the board?
Regards
Phillip

HiFiBerry team Hi Phillip,
the profile is automatically stored on the DSP. However, it seems, we have a problem that the default volume isn't set correctly after a reboot. We'll look into this.

Phillip Müggler Hi Daniel,
How can I set the default volume without reprogramming the DSP?

HiFiBerry team I don't know the internals of the Beocreate software in details, our programmer from B&O will look into this.

Tuomas Hello Phillip!
There's two possible issues at play here.
- #1: It could be that the volume level that is set through the setup tool is not recalled at startup. However, this should not result in a quiet sound as the speaker by default is at full volume, and the system will only lower it if it's set to be lower than maximum.
- #2: It may be that the sound profile is not correctly flashed to the DSP so it gets erased every time you disconnect power, and as such you will get a previously stored, possibly factory-installed program that is much quieter. I have experienced this myself.
There's not much you can do about the first, because it's something we have to fix in our end if we determine it's an actual issue (and not just a theory).
To check if #2 is the issue, here's what I'd like you to try. It requires you to physically access the amplifier, so you need to open up the loudspeaker if it's installed inside.
- Power up the system normally.
- Once it has booted up, look at the amplifier board and find a jumper called selfboot. It is currently in place, but you need to temporarily remove it. Just set it aside.
- Go to the setup tool and now install the sound profile you want. Wait until the process completes.
- Power down the system.
- Reinstall the selfboot jumper, so that it connects both pins together.
- Power up the system normally and then test if volume is still low.
Let me know how this goes and we can figure out the next steps.
All the best,
Tuomas from Bang & Olufsen

Phillip Müggler Hi Tuomas
Somehow this solved all my problems. It even plays the start up sound now. I'm guessing option #1 is a theory unless you have a better explanation.
Thanks for the help - hoping it was the last time opening the case :-)

HiFiBerry team Hi Phillip,
do you use a Beta-board or the "normal" production version?
Best regards,
Daniel -
Phillip Müggler I had issues with the first board I received so you reshipped another to me. So I really don't know.
-
HiFiBerry team Ok, then it's clearly the production version.
Best regards,
Daniel -
g.nigro are there differences from Beta-board or the "normal" production version?
-
HiFiBerry team There are minor changes, but they should not impact anything. I jut asked because we have seen some inconsistencies in the EEPROM programming behaviour and I wanted to check that the board release isn't the root cause.

Robert Holstrom I am getting along on the Beocreate 4 channel amplifier. I can change the levels via SigmaStudio in real time but need more volume. I will be using it eventually as a bi-amp. It seems that writing to the eeprom at https://www.hifiberry.com/beocreate/beocreate-doc/beocreate-use-sigmastudio/ is not writing properly to the board. The sound always comes back at the lower volume not the volume programmed in via SigmaStudio. I do a verify and it says it is 00 and expecting AA. I have a beta board. Is there a solution to writing the code to the epprom?

HiFiBerry team Remove the selfboot jumper before programming via SigmaStudio.
Best regards,
Daniel -
Robert Holstrom OK got it! I needed to take off the jumper before power up, program the DSP, power down, connect jumper. power up. I figured I could just remove the jumper after initial boot.

Duncan Hi guys,
How do you know if you have a beta board?
I do the verify thing in Sigma and get the OO/AA error regardless of how I program the dsp. Also returns a kernel panic in memory DMO Bank 3...Any thoughts?
-
HiFiBerry team Hi,
you can ignore these errors. There is still a bug in the TCPServer that return wrong result on reads
Best regards,
Daniel -
Duncan Thanks Daniel,
Any news on a release date for your eagerly awaited updates? -
HiFiBerry team We have a test version running, but it will need more tuning. I hope we can release this within the next week.
Best regards,
Daniel -
HiFiBerry team If you want to test by yourself, just install it with this install script:
https://github.com/hifiberry/hifiberry-dsp/blob/master/install-dsptoolkitYou need to stop and disable the "old" SigmaTCPServer as this is a completely new implementation.
Best regards,
Daniel
