Recently I bought the following models. It works just after the first installation, but no sound after rebooting.
- DAC2 Pro
- Pi 4 2GB
- Raspberry Pi OS 2021-01-11-raspios-buster-armhf-lite
- DSP Profile: https://raw.githubusercontent.com/hifiberry/hifiberry-os/master/buildroot/package/dspprofiles/dsp-addon-96-13.xml
After rebooting, I could not install the DSP profile because following error was returned:
Failed to install DSP profile dsp-addon-96-13.xml
Disabling shairport-sync, sigmatcpserver, start sigmatcpserver manually, then install dsp profile yields following error log.
sudo /usr/local/bin/sigmatcpserver -v

Executing "dsptoolkit reset" makes it possible to output sound from DAC, but still no DSP profile uploading is possible.
