HT-XT1 sound bar , sound stutters

davemaden — Wed, 21 Jan 2015 21:18:53 GMT

i have a sony HT-XT1 sound bar connected via HDMI leads to a sony kdl-40ex503 tv . all works ok but when i connect an amazon fire tv or an apple tv 2 or my blu ray to the sound bar ( even if they arent plugged into the mains ) the sound stutters every 5 seconds , when trying to watch the digital tv channels . yet the sound is fine if watching the fire tv or any device that i connect , its just when the aftv or the atv2 or blu ray are connected that i cant watch the tv channels without the stuttering. can someone help with this ? it has been working fine for about a month .thanks

Hi there

Ive been having a think about this one (and im going to think outside the box too). You may be experiencing what I am experiencing at the moment. I'll explain. When a certain device on my setup is switch on (connected via HDMI), I loose Freeview signal on some HD Channels. I believe this is EMI (ElectroMagnetic Interference). You might be experiencing the same.

You stated that when devices are connected to the soundbar (even if not plugged in), then the sound stutters when outputting the TVs audio to the soundbar. Audio is fine when watching devices directly connected to the soundbar. This therefore indicates to me that there is some type of interference, most likely on one or two cables. The most likely two cables that could be effected in this scenario is the aerial lead connecting to the TV and the HDMI cable from the TV's HDMI-ARC port and the soundbar.

What you can do, is then test part of this theory out. Instead of having the HDMI cable from the TV to the soundbar, connect an optical cable instead. Test this and see what the results are. Is the problem fixed?

There is also a small type of component that you 'clip' onto aerial and HDMI cables. These are called Ferrite Cores. They are pretty cheap on Amazon, you just need to get the right size for the cable. I cannot vouch for them (yet) as I havent tested this out in my situation - will be purchasing them tomorrow So I really do not know if it works.

That really is the only thing I can think of at the moment, in regards to the cause of your problem.

Hope this helps.

Cheers

Hi there

Just seeing how you got on with things to be honest. Are you still having problems? If you have had a software update recently, it doesnt hurt to factory reset the TV. Its in System Settings > General Setup

Cheers

Hi , the problem is to do with the software update , as its affecting the HDMI(ARC) port . The book fr the sound bar says , if you have an ARC hdmi port , that you should connect to that , however this is where (ever since the s/ware update ) im getting the sound stuttering every 5 seconds . But ivefound that if i connect sound bar to another port ( none ARC ) and also connect the optical lead from tv to sound bar , then this stops the stuttering , so the equipment is ok . Thus making me think its the s/ware update causing the problem , ive e-mailed Sony and im awaiting reply . thanks

Hey there

Please post back when/if Sony support come to a conclusion. In curious to know myself. Certain problems interest me from time to time (as in 'curious'), and this is one of them

Hi there

Considering the other problems you are now having - might be time to consider that you have a faulty soundbar? Is there a possibility you can get it replaced from the retailer you purchased it from?

In regards to your latest problem. See if the following works.

Turn TV off from the power mains (not just standby)
Disconnect HDMI cable
Turn TV on again (leave switched on for 2 mins)
Turn TV back off again (from the mains)
Reconnect HDMI cable
Switch TV back on again.

Cheers

just an update i disconnected everything and did a factory reset on tv , then connected tv to sound bar and all works fine again , but if i connect the amazon fire tv to the sound bar and watch xbmc on aftv all is ok until i go back to tv and now there is no sound at all , if i turn tv and sound bar off and disconnect hdmi lead from aftv to sound bar , then turn tv and sound bar on the sound is back on , i think the aftv and soundbar arent compatible , yet when connected it plays ok ? why could this be ? thanks p.s. and i have unplugged the optical lead and put hdmi lead back into ARC port .
