I have WD TV Live with firmware Release 1.06.15 (8/9/2011) and ONKYO home theatre 7.1
After WD has been updated the back speakers stop work. I have read manual and realized that in Video/audio settings - Digital - (S/PDIF, HDMI) - Select this option if you are using a S/PDIF (optical) or HDMI connection to output 5.1 surround sound.
What I shell to do if I have 7.1 audio system? Is it possible to downgrade firmware or programmers from WD will fix it in the next firmware?
