Could anyone advise me on getting audio to work with 7.1 channels using the following device:
Noblik 7.1 Sound Card Usb 2.0 Sound Card Cmi6206: Amazon.co.uk: Electronics
I am using a Rpi4 on the LibreElec 9.2.1. Setting the number of channels to 5.1 works as expected. However I get no audio if i set it to 7.0 or 7.1. Additionally, when set higher than 5.1, videos play for a few seconds (silently) then freeze. I can stop the video, return to the settings and switch to 5.1 to get the video to play perfectly.
I plugged the audio device into my x86 LibreElec machine (9.2.2) and it works perfectly in 7.1. I tried copying the audio settings exactly from the x86 to the pi but no audio configuration seems to make any differene.
I have attached a log file where I switch from 5.1 to 7.1 and then attempt to play a video.
Any guidance would be welcome.
