Original non-mod S3 Audio out via Fiber optic It happened just couple days ago after i switched back from dvd player, hdmi only used for video for my pre-pro via a hdmi-switcher. I lost the audio completely, my pre-pro is reporting no audio signal. Reboot s3 fixed it. Then come yesterday, same thing happened on recorded shows only (all of them ). The audio was on for like 1-2 seconds then lost audio signal(indicated by pre-pro), the different is the Live channels all have audio. The on-off audio sequence can be repeated on every record show when i play it. Again, reboot s3 fixed it. I tried reboot everything prior to s3 and it all point to s3.
