[Solution] ALSA lib conf.c:4514:(parse_args) Unknown parameter AES0

I would get this error while trying to watch certain movies over HDMI with XBMC on my tv and no audio would be available.

ALSA lib conf.c:4514:(parse_args) Unknown parameter AES0
ALSA lib conf.c:4647:(snd_config_expand) Parse arguments error: No such file or directory
ALSA lib pcm.c:2212:(snd_pcm_open_noupdate) Unknown PCM plughw:0,0,AES0=0x6,AES1=0x82,AES2=0x0,AES3=0x2

My solution to this error is in audio settings section under passthrough output device choose custom and enter whatever output you use for your HDMI mine is “plughw:1,7”. To my understanding it’s an ALSA issue with ac3 where it passes the wrong output parameters, and the AES0 parameter is supposed to set the digital audio output connector in the right mode. Thats my understanding from what I have read about it so google it if you want to find out more on this. As for me am content that it all works and I can stream all my stuff with sound to my tv.
