Hi, guys, I've been using Z10 with computer monitor for almost 6 months without any major problem. Now I bought a 4K TV set (Sony BRAVIA KD-55XF9005) and I encountered strange problem. When playing audio with SPDIF electric coax out (to Cambridge CXA80) while the TV's ON, everything is fine, when turning the TV OFF ( well, it's not completely OFF, kind of standby) every cca 30s the front display shows jump from 4K to 1080p and back with audio dropout. I tried to ignore EDID, selected fixed resolution, disabled Bravia sync, nothing helps. Seems like Z10 is regularly handshaking HDMI with Bravia, which causes the digital audio dropping out. Now I always unplug HDMI cable from output to keep audio uninterrupted, but this practice is annoying... Would you see any option I haven't tried? Thanks for any insight. Richard, Czech Rep.
