Hi Daniel,
Since an update of Raspbian, I do not have audio output anymore on my card DAC+DSP.
A worrying error message is displayed when i make 'dsptoolkit apply-rew-filters filters.txt':
'14 filters given, but filter bank has only 0.0 slots'
Before the update, I had 16 available slots!
Is the DSP damaged, or is it possible to reinitialize the card?
I need your help.
Best regards,
Christian
The update might have damaged the file system or deleted the DSP profile on the file system. Just re-install the profile to the DSP.
However, an OS update should not delete this. Therefore there is a risk that the file system itself had been corrupted during the upgrade.

Daniel
Thank you for your quick answer
I have re-installed the profile with the command:
dsptoolkit install-profile https://raw.githubusercontent.com/hifiberry/hifiberry-dsp/master/sample_files/xml/dacdsp-default.xml
--> DSP profile https://raw.githubusercontent.com/hifiberry/hifiberry-dsp/master/sample_files/xml/dacdsp-default.xml installed
But I always have the same message:
'14 filters given, but filter bank has only 0.0 slots'
What should i do?
Best regards,
Christian
My guess is that the updated corrupted some files or the whole file system. You can try re-installing dsptoolkit, but you might need to re-install the whole system.
Best regards,
Daniel
Re-installing dsptoolkit.

Thanks for your help!

For a short test, HiFiBerryOS might be faster as the image it quite small:

Hi Daniel,
I have re-installed the whole system (archlinux arm) on rpi3.
All is OK!
Thanks!
