Updated to OpenElec 6.0, when I start playing video files with DTS or Dolby audio I get very loud speaker cracking popping, sounds unhealthy for speakers. Only when starting playback, then it plays perfect and same thing happens when stopping but much less pounced crack/pop.
R-Pii 2 > HDMI > Receiver, with passthrough enable. If its pcm or passthrough off it doesn't happen.
I remember it use to happen on 5.0.8 too but was very slight, that you not notice unless you really try to listen for it.
I do reset on audio options. Is there any audio option/settings that may help me?

Does enabling/disabling omxplayer affect it?

What is make and model of TV/receiver?
Does TV support AC3 passthough? If so, do you get cracking if you bypass receiver and connect direct to TV?

The TV is LG 55LA8600, the receiver is Sherwood RD6506. It will passthrough dolby and dts.
I change the way it was plugged in to this;
R-Pii 2 to HDMI to TV to Optical Cable to Receiver
DTS
MMAL acceleration, harsh sharp speaker crack.
Omxplayer acceleration, very subtle soft pop.
Dolby
MMAL acceleration,harp speaker crack.
Omxplayer acceleration, very subtle soft pop.
(sorry I edit, dolby reply)

I was more interested in leaving out the receiver completely and using the TV speakers. Do you get the cracks then?

Gotcha,
R-Pii 2 to HDMI to TV
MMAL acceleration, I get constant static on dts and dolby.
Omxplayer acceleration, no problems at all.

I don't expect this is a new issue, we've just changed the default player from dvdplayer to omxplayer in OE 6.
I'd be interested if OE 5 behaves the same way with omxplayer disabled and MMAL enabled (I suspect it will, but if it doesn't then there is something to investigate).
Also do you have any other kodi device? I'd be interested if that also has the problem (i.e. is it kodi/AudioEngine related, or something in the Pi firmware).

I don't have any other Kodi devices unfortunately.
I loaded up my backup of OpenElec 5.0.8 and tested with MMAL acceleration and did not get the speaker crack. I doubled checked that passthrough was enabled, and could see the receiver display showing dts or dolby when playing each.

I have several files that are DTS and Dolby. I have yet to experience this issue. I am using Pi2 to Onkyo Receiver to TV. Passthrough enabled. On OE 6.0
