Re: Bluetooth Audio Delay

Hello it says ignite 150u. ? Lol.

It is just when pairing to the Ignite boxes I have a problem. I’ve tried two sets of Apple AirPods, 2 Wireless Bose and two sets of Beats wireless. 6 different kinds. It’s definitely the Ignite. I have no issues pairing them to other things. It can start ok and then quickly starts to lose sync. It’s been like it for months now. I rely on them so I can watch tv and not wake my husband at night… very frustrating.

I'm not a Bluetooth headphone user so, unfortunately, I cannot personally recommend any products that are known to work.  Unfortunately, some Bluetooth chipsets simply do not work well together, and the Internet is filled with reports of audio and video getting out of sync with practically every kind of device out there.

 

Bluetooth works fine with audio, where any lag or latency is not noticeable, but video is a toss-up.  Even buyer's guides, that list the best Bluetooth headphones, often qualify their recommendations with things like, "best for Apple users".  For example, Apple, Beats and Bose Bluetooth headphones and earbuds work well with iPhones; they pair easily, integrate fully, and with that level of compatibility, iOS devices can also compensate for Bluetooth latency so that they "just work", or appear to just work... but use another brand of untested/uncertified headphones or audio receivers and you are back to a situation where you may get annoying delay and out-of-sync video, with no way to fix it.

 

Out-of-sync audio/video is a common problem with the Comcast-designed set-top boxes, so much so that they even have an answer for this frequently asked question in their support article:

 

The audio is not synchronized with the video when I use my Bluetooth headphones. Is there anything I can do?

Your X1 TV Box or Flex streaming TV Box automatically makes adjustments to sync the audio and video, but some headphones are known to have compatibility issues. Occasionally, restarting your device can help. Typically, however, the best option is to try different headphones.

 

I have not found any web pages that list headphones that are known to work well with Rogers Ignite or Xfinity X1 set-top boxes.  Comcast does not list which products they test with.

 

However, one easy thing that you can try is go to "Settings / Device Settings / Audio" and change the HDMI Audio Output to Stereo.  This technically should not have any effect on Bluetooth audio but it does affect how the set-top box processes audio internally, so there is a chance that it could help with Bluetooth.

Re: Bluetooth Audio Delay

Not sure if you have this option, but try to sync to your TV instead of the Ignite box.

Re: Bluetooth Audio Delay

So, If I am using them to watch tv it’s usually ok. It’s the stuff that I’m watching that I’ve PVR’d that doesn’t ever sync up.

That's interesting.  It has been reported and complained about that live TV streams and the content stored "in the cloud" (PVR and On-demand) are encoded differently, and the Ignite set-top box would also need to decode and process this content differently.

 

Is the audio on the recorded content ahead or lagging behind what you see on the screen?

When watching live TV, do you find that some channels or programs are consistently out of sync while others are not?

Also, is the all behaviour (correct and incorrect) consistent with all the headphones/earbuds that you have tried?

 

This may be a bit tedious but it may be possible for this to get fixed if you could document the circumstances where A/V is in sync and when it is not, and if the audio is ahead or behind the video that you see on-screen.  Please report it here so that others in the Community can confirm your findings, and please also share what programs you are watching/recording/testing with.  If others can confirm your findings, then the next step is to report this to Rogers, and the best (and easiest) way to do this is to send a private message to the @CommunityHelps  team.  They can then copy/paste the information that you send them directly into a support ticket and escalate it to the support teams internally.  (Don't contact Technical Support by telephone for stuff like this.  They're great people but critical details may not get logged into the ticket if the agent misunderstands and/or does not document all that you said accurately.)

Re: Bluetooth Audio Delay

The sound is lagged, not the video. It’s a lot of my reality tv (90 Day Fiancé stuff). Maybe it’s a sign? Lol

I would suggest that you watch a program (that is known to be problematic) live and record it at the same time.  You can also play recorded content while it is being recorded.  If the live stream is fine but the recorded version is not, and everything is fine again when you go back to watching the live stream, then keep the recording on the cloud PVR and report this (including the time/channel that the program aired) to Rogers.

Re: Bluetooth Audio Delay

I’ll have to try that and test it out. I did try multiple Bluetooth devices with it (to answer your prior question). It’s definitely the box it seems.
