It does sound similar to the other post.

I see. I would like to nail it down to the issues with HDMI Arc, and that it hasn't been standardised across the industry. I however would like to try one thing. I'm not too sure how prominent it is within Sony TV's however, but I would like you to look for a specific setting within your Sound Settings.
So go to your Sound Settings. Look for HDMI Audio Format. If you don't see it, look under advanced/expert settings. If you do find this setting, I would like you to make sure it is set on PCM and not Bitstream. This may be able to improve the delay between the TV and the Soundtouch 130.
Let me know if you can find this. Like I said it might not be there but let us know anyway. Thank you.
