7.1 usb sound card only outputs stereo in kodi but with alsa it can play 7.1.

Hi.

I have an issue I haven't been able to fix. The usb sound card [asus xonar u7 mkii] when selected to output analog 7.1 in kodi only outputs analog stereo.

The kicker is that when using ssh the alsamixer shows all channels and playing 7.1 wav files with alsa works. However I try none of the setting in kodi give the slightest hint of more than stereo. It is as if it does not know that there are more channels. I tried with alsa configuration but I don't seem to lead me any closer to a fix.

Finally I have tried to perform a linux ritual dance: did not work. Any help is appreciated.

Are you actually playing 7.1 content? or are you wanting to have stereo upmixed to 7.1?

Can you post a Kodi debug log?

Yes I am trying to play 7.1 content which on other linux os but same hardware produces 7.1. However the video playback is stuttering.

Here is the log:

You need to post a full log that includes attempted playback. Cut logs don't help anyone.

Added full log. Sorry for the cut.

2021-05-19 16:31:56.453 T:4796 INFO <general>: Running on Hardkernel ODROID-N2Plus with CoreELEC (official): 19.1-Matrix, kernel: Linux ARM 64-bit version 4.9.113

Interesting... Asking support on the LibreELEC forum when you have CoreELEC running on your device

**lrusak** · May 19, 2021 at 6:11 PM Official Post

The log provided as Klojum pointed out is from CoreELEC.

The log also doesn't show the USB soundcard and it doesn't show you playing any media.

travioli · May 19, 2021 at 7:23 PM

Added full log with usb and playback (It was to big hence zip ). @Klojum it was my belief CoreELEC is the same as LibreELEC but for odroid n2+ (I hope I haven't offended anyone). @lrusak @Klojum thanks for helping me.

CoreELEC is very much not LibreELEC.

I'm not 100% what is going on here but all your channels aren't being recognized
