Frequently Asked Questions
Why does IPTV audio cut out on my soundbar with Nvidia Shield?
Variable bitrate EAC3 streams cause your soundbar's digital processor to repeatedly lose HDMI clock synchronization.
How do I disable Dolby Digital Plus on Shield TV?
Go to Settings > Display & Sound > Advanced sound settings > Available formats > Manual > turn OFF E-AC3.
Does turning off Audio Passthrough reduce quality?
No, the Shield's internal PCM mixer decodes the exact same digital audio without clock drops.
