Hello, Guys
People , that owns the RX A8A or the A6A, you might need to check your Main ( Front L/R Speakers ) on this newest 1.59 Firmware Update, because i needed to do ( Initialization ) on the System Setup ( to do a Restores the Default settings for the unit ) on my A8A , I didn't notices until i was trying to listen to Spotify on 2 Stereo mode, and i couldn't even use the tone test sound ,, i might had some interference during the firmware update installment through Wifi , but yeah, again i tired the Stereo mode, my Main Front wasn't working , i was shocked , and trying to find solutions to fix this issue, so i went to the Option screen menu , system , initialization - Now, problem solved !!
