I made steps according to this HifiBerry document: hifiberry-dsp/rew-basics.md at master · hifiberry/hifiberry-dsp · GitHub
I created and exported filter definition from REW as text file. I imported this file to DSP by command
dsptoolkit apply-rew-filters filters.txt
Filters were imported OK a were functional (tested by measurement microphone).
But after that (according to provided document) I stored filters to DSP by command
It resulted to reseting (deleting) imported filters. Result was the same as using command
It is bug. In this situation is mandatory to reimport filters every HifiBerryOS restart. Can you provide some solution of this problem?
Thanks in advance.
