Update my WDTV Live yesterday and Optical Audio has stopped working, was working fine before this upgrade.
I have the same problem - I connect my WDTV via HDMI to my TV and optical to my amp and I get no sound whatsoever now for any file format! How can I roll back the firmware? When can this be fixed???
Optical audio works for me.
Although I didn’t have to, try doing a reset.
