Author Topic: Wrong audio tracks on HDMI input Joost Vandertogt Film Handler Posts: 8 From: Zoetermeer, ZH, The Netherlands Registered: May 2016 posted 08-15-2016 10:22 AM                     Update: We had a Konig single UTP HDMI extender on stock, tried with MacBook at the AP20 and extender to projector. With audio output at HDMI Decrypted the audio was routed correctly! So I just ordered one more so we can place the HDMI source at other locations than directly next to the AP20  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

I presume that it only works if you haven't channel mapped the system.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 08-16-2016 06:31 PM                     As far as I understand, it is meant to adjust channel mapping for live transmissions, as such for it to work, you would need to create a LiveEvent, and then assign that mapping to the 'live' CPL and play it? There doesn't seem to be a way to remap HDMI audio globally. - Carsten  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

I gave it a look and from Content Manager, you can go to any CPL and set up its unique channel mapping.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 08-17-2016 08:42 AM                     That's right, it does work for any CPL (type), as you can assign a mapping to any CPL present on the server. But to have an effect on HDMI->AES, you need to assign the mapping to a live event CPL with HDMI referenced as the source. - Carsten  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 08-17-2016 09:24 AM                     But does this work even if one has assigned channel mapping via the control panel?  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 08-17-2016 10:53 AM                     Yes, there is a global mapping which is used when no per-CPL mapping is applied (which is 'always' for most systems, I guess) . But if AES/internal and IMB/HDMI channel assignment is different, you ruin the DCI channel assignment when trying to adjust for HDMI. The per CPL mapping was probably introduced for SMPTE DCP dynamic channel routing. We'll see if that will ever become a practical reality... I have no Doremi IMB system in daily use, so I can't check into this on a short term. - Carsten  |  IP: Logged
