Hi All,
Firstly wow! I haven’t looked at Volumio for a few years, its so good, very slick. Devs have been doing a great job, thank you.
Have downloaded latest image and configured Volumio on my PI4 and Topping E30 DAC, all working perfectly. No arrors installing CamillaDSP.
However, when I enable the CamillaDSP Plugin and reboot I get;
Camilladsp failed to start. Check your config
The Plugin shows HW-Detected-S32LE Or HW-Detected-Special As detected outputs and selected demo filters. No sound
