Wrong mapping of channels to HDMI ports

Asked by wannabeelinux

After installing recommended driver nvidia-driver-460 for my NVIDIA GeForce GTX 1050 Ti the different channels are mapped wrong to my 7.1 surround sound set. Playing sound in stereo works fine but when playing a movie voice is not send to center speaker. Is there a way to change this mapping? I'm running ubuntu 20.04.

Check to see if the HDMI is plugged in to the HDMI [ARC] of your TV or Monitor.

After an Nvidia driving force replace, the walking kernel continues to be the usage of the vintage Nvidia module, and also you get such mis-match messages. Simply reboot to restoration this, getting the new module into the kernel. See more here https://jacobmartin.com/

Can you help with this problem?
