Equaliser settings not changeable when using radio..... fine with other music though

Has anyone had this problem? Playing an MP3/Vorbis/Wav (etc…) file and I can switch the e.q. settings. Playing radio I cannot switch e.q. settings. What the??

Your .mp3’s, etc. are digital and so is the EQ. The FM radio is analog; the equalizer won’t work on it.

Oh I didn’t realise… thanks for the heads up
