Thanks for the confirmation Vladimir. I don’t have any issues with AAC stereo; it’s only the surround format getting distorted.
Also, I did some troubleshooting and found that the decoding gets distorted when Kodi Settings -> Audio -> Audio Output Device is set to ‘ALSA AML-AUGESOUND, HDMI’. I have tried remapping the format to all possible formats supported by the receiver (Neural X, Dolby Surround, Multi-Channel Surround etc.), but to no avail.
While setting this to ‘ALSA AML-AUGESOUND, HDMI Multi Ch PCM’ mitigates the issue, my receiver is unable to display the type of decoded audio. I have been using the VIM3L with the parameter set to ‘ALSA AML-AUGESOUND, HDMI’, with which things were working fine, until the recent automatic (my update method is set so) CoreELEC upgrade to the VIM3L.
What’s your receiver, btw?
