The EQ (bass and treble) settings can be adjusted up to plus 10 and down to minus 10 and the sub setting can be adjusted up to max at plus 15 and all the way down to minimum and it makes no difference at all to the sound which is horribly flat. Turn off sub. Turn on sub. Turn on loudness. Turn off loudness. Doesn’t matter the source either be it NAS drive local library or Spotify or 5.1 video sources. I don’t know if this is related to an app update as I haven’t used it for a couple of weeks but I strongly suspect it is.
I’ve restarted the phone, tried a different controlling device. Same. I unplugged the Amp, the sub and the surrounds for 10 mins but on startup still had the same problem. I’m not sure what else I can try. Any suggestions?
