I'm plaanning on going the same route: Hifiberry Digi2 (Pro) + DSP Add-on foor room correction. But your post confuses me a bit if it's working fine with Squeezeplayer or not. Especially since you mention "Also, their (experimental) room correction feature didn't work for me." But you end with "This is just a heads-up that it does all work rather well". Would like to get more details. More in particular if the combo Pi4 + Hifiberry Digi2 (Pro) and DSP add-on is working for (simple) digital room correction. ------------------------------------------------------------------------ vco1's Profile: http://forums.slimdevices.com/member.php?userid=68036 View this thread: http://forums.slimdevices.com/showthread.php?t=114806 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
