My M12 loses sound/power after x mnutes

This would not be related to the dipping issue no.

If it only happens on Optical then we need to identify the source devices issue.

If we can test it on another device/the same device using AUX or Bluetooth we can then ascertain if it is that device and connection.


Hi.  This same thing happened to my M12 Orbitsound sound bar yesterday evening.  Switched itself off whilst watching TV, via optical cable.  Bluetooth checked at the time, working OK.  Was able to switch the sound bar back on again, but no sound via optical cable.  Sound would return after being left on for about 15 minutes.  Then problem repeated itself after a while, and throughout the rest of the evening.

Any thoughts?

Thanks

Hi prestonposse,

I moved this out of A series and into M series issues.

Can I ask does the audio still work okay on Bluetooth and AUX or does the same thing happen?

Can you tell me about devices hooked up to the TV, Sky/Set top Box, games consoles etc.?

Thanks for your quick reply, Simon.  I've done some more investigating today.

The optical feed from TV is OK for 30-45 minutes, then the sound bar switches itself off.  I can switch it back on again, but the optical audio is silent.  If at this point I then switch the input to Bluetooth source, the sound is OK through the sound bar.  If I switch back to the TV optical feed (still no sound) and leave connected, the optical sound will re-start again after about 20 minutes.  Then the sequence repeats itself.

I've not tried the AUX input.

There is only one device connected to the TV, which is a Humax Freesat receiver.

Looking forward to hearing your thoughts.

Hi prestonposse,

Hi Prestonposse,

Mt first thought is the Humax, can you attach the optical cable directly and see if the issue occurs there?

You may need to change the SPDIF/Digital Audio/ out to normal/PCM/stereo or if its a newer box set Dolby to off.

I would also be interested to see if we can try any other device either via Bluetooth or AUX and see if it still happens.

We are dealing with one of three things listed below in order of likelihood:

1. The bar is turning itself off/disabling optical to protect itself from an errant signal, most likely from the TV.
2. The bar is turning itself off/disabling optical due to a fault, it would be unusual for this to be so regular and/or not to happen fairly quickly. It also should affect every source/input, not just optical.
3. The TV itself has a fault and stops outputting audio or starts outputting an incorrect signal, this is unusual but not unheard of.

With that in mind I think it will help if you could give me the model number of the TV and Humax box, and details of any Consoles or Blu Rays etc.

Hi Simon.  I've done some more investigating today.  The problem also happens with Bluetooth input, in this case from an iPad, though perhaps not as frequently as the optical input.  The M12 ran for about 4 hours today with Bluetooth input and then switched itself off (iPad still outputting, Bluetooth connection still established).

I tried connecting the optical lead directly to the Humax box, rather than the TV.  It ran for 4 hours and then the M12 switched itself off.  I immediately switched the M12 back on and the sound returned.  However, after another 35 minutes the M12 switched itself off again.  This time when I turned the M12 back on again the sound remained off.  I left the M12 switched on and  the sound returned to the M12 after about 10 minutes.

The TV is a Toshiba.  The Humax box is Foxsat-HDR.

I've had the M12 for a few years now.

Hope this helps.

Hi Prestonposse,

That sounds like it may be the bar then.

We can possibly get it in for repair, is the bar over two years old?
