equalizer still not available after wp 8.1 update to 512mb devices!!!

still equalizer settings have not been provided to 512 mb devices . the most common of them lumia 520. will it be available during the ota update?????

its not due to 512Mb ram , Lumia 620/720 have 512 Mb ram and they do have equalizer , this will never come with Os update , its all dependent upon hardware and firmware update + audio update . Lumia 520 lacks equalizer hardware :sad:

It may not be available anytime soon. 512mb devices(Lumia 520 , 525) have some drawbacks which doesn't meet the requirements to run the equalizer. Sad 😞

just Update windows 8.1 preview, Audio Equalizer Available for 720 lumia Don't know about 520 Because.
I think There is no supporting hardware available in that device.
