HDMI channel layouts get messed up

[JJ_V]

Hello,

I yesterday encountered the situation where the audio output channels in 5.1 mode through hdmi are wrong. It is the problem already described in this thread:

I was using the latest drivers (obtained from Windows update, they are later than the ones on the Intel webiste). As an attempt to fix it, I installed the latest drivers from the Intel website. This fixed it, but of course there was a reboot inbetween. I have no dump of the Intel information from the time it was wrong. When it goes wrong, it goes wrong for all applications (games, etc).

I have no idea how to reproduce it. The only thing is that I was trying to get MPC-HC to use the MPC-BE audio renderer, which uses WASAPI audio output. The reason I wanted WASAPI is that it allows the system to output the same channels as they are in the source material (ie a stereo source will result in a stereo signal, a 5.1 source in a 5.1 signal). I only used stereo sources and 5.1 sources and no program crashed or was forcefully closed. Not sure if it is connected, but I could not get it to work. Using the WASAPI output, the system output a signal that was incompatible with my receiver, even though the limitations of my system were set correctly. But that may be a different problem which I need to investigate further. This post is about the channel layout.

Is there already solution to prevent the hdmi channels from getting messed up? (e.g. is it connected to using WASAPI?) Rebooting is not always an option (e.g. if it happens while the system is recording TV programs, you cannot just reboot). I have a Intel 4790K on an Asus Z97-A mainboard.

Best regards,

Jörg
