This is my first post in this form, I am sure I will get a good help on this. Please bear with my layman explanation.
I am using Marantz SR8012 for the past 6 Months. when I bought this system I did a Firmware update everything went cool. Last week I again got a firmware notification and went for it, After the update, I noticed that there is a problem with Dolby (Maybe Dolby upmix) , When I play an audio FLAC or WAV formate I usually play in stereo and sometimes I listen on Dolby mode, but now when trying to change on Dolby I don't get a clear music instead I get some noise mixed music that I can't hear.
I want to know 2 things,
1. Is there a way to fix this Dolby upmix, has anyone experienced this before.
2. Is there a way to revert firmware back to old version, if there is a way to do this will this fix my problem.
Thanks in advance..!!
