Don't know particularly, but they do have this page https://www.oppodigital.com/Support.aspx
so I'd at least contact them to see what options you have in that regard.
My 203 hasn't had any issues so haven't had a reason to contact them myself, tho. We'll see what they're providing if/when that day comes but at my age the Oppo may outlast me
. I also use several Sony bluray players for my SACDs. I don't need analog output, tho.
