As mentioned in the question, although I know this is a bug in the VU Broadcom chip 7444, at least switching back and forth to other channels on Openpli 8.3 and then switching back to the current AC3+audio channel can restore sound. However, no sound is heard on Openpli 9.0 no matter how it is set

Are you speaking of Vu+DUO4KSE? Or Vu+Duo2?

I have 4K and have no issues in playing AC3+ on TV...But there are issues with passthrough.

So what is your issue exactly?

Vu+DUO4KSE  But there are issues with passthrough.    However, on other ATV EGAMI PLI8.3 systems, it is possible to switch to another channel first and then switch back to solve this problem. After refreshing, PLI9.0 has failed

To me, the AC-3+ passthrough audio is really a big issue... I currently have a Qviart Lunix 4K connected (HDMI CEC) with a Denon AMP and TV, using PLI 9.

Everything works fine if I leave audio in the downmix mode but, of course, no Dolby audio would be available.

Most channels are broadcasted with either MPEG, AAC or AC-3 audio, and there are no problems in passing-through the corresponding audio to the AMP or the TV.

Conversely, one provider broadcasts AC-3+ (Dolby plus) audio only, and I found no way to passthrough them to the AMP. If I switch the audio of the various channels to and from the passthrough/downmix modes, then the audio signal is gravely disrupted and I need to restart the box in order to restore a normal audio signal.

So, it would seem that AC-3+ audio is not supported by the box. However, and very surprisingly, if  I play a mp4 recorded file having the AC-3+ track only, then the audio works great in passthrough...

Therefore, the problem should be in the software rather then in the hardware... however none of the various E2 images I've tried so far were able to address the issue.

 

Any suggestion to fix the issue or to buy a new E2 box that works better with Dolby Plus?
