Title: No audio if raw mode
Post by: ClaudioG on March 22, 2024, 10:04:55 AM

My Z9X is connected via HDMI to the Yamana RX-4A4 amp.
It worked perfectly until yesterday.
Today it only showed the video without sound.
I changed the HDMI cable but the problem persists.
I have agreed that if I change the audio output from RAW to LPCM 2 the audio will be heard.
I tried using the optical output with the same result as HDMI (RAW no audio, LPCM2 yes audio).
Do you think it's a Zidoo hardware problem?

Thanks for your attention.

Try resetting the amp. Either a factory reset if it can do that or unplug it and leave for a few minutes before turning it back on.

If the Zidoo can output video+PCM over HDMI then it's extremely unlikely that there is a hardware problem. Much more likely a connection/handshaking problem with the amp.

Thanks for your attention!

If I connect the Zidoo directly to the smart TV via HDMI the result is identical to that described above.

I still think it a config / handshake type problem between Z9X and the amp.

Try resetting the Z9X completely. IMPORTANT, MAKE SURE YOU HAVE A Z9X AND NOT A Z9X PRO BEFORE DOING THIS! Z9X PRO USES DIFFERENT FILES:

Done.

Turn off the amp for 5 minutes and... all OK  ;D

Thanks
