Dolby Atmos audio drop out

[gpb156]

When streaming dolby atmos from Sky Stream e.g. Netflix/Apple TV audio can occasinally drop out for about 2 secs. Seems completely random, may happen once or twice in an hour.

Just wondering if anybody else has this problem with the sream puck or is it something to do with my set up.

Audio pass through set on puck, also bitstream pass trough on LG TV. Earc HDMI 2.1 connection to LGS75Q soundbar.

This a bit frustrating as Atmos audio sounds great.

Are you using the same speed and spec of HDMI cable on both parts of the chain? ie puck > TV > soundbar?

Have you tried connecting the puck directly to the soundbar?

I have this same issue, did you fix it?

[Alistair+Burns]

I get this occasionally and just put it down to my impression the software is still effectively a beta.

Just now it became chronic watching the football on TNT Sports Ultimate. Unplugged and restarted and the problem has gone for now, missed a goal as well of course. Might be a buffering issue given that the restart cured it this time and previously.

I get this too especially if watching uhd hdr with Atmos.

The pucks are under powered and don't have enough RAM to cope with high bit-rate audio.

I bought two new 2.1 hdmi cables, they arrived today, watched 2 hrs so far no drop outs!

@Jones_The_Cat Using 2 high speed HDMI cables puck to TV, TV Earc to soundbar. Not same manufactuer so maybe that could be issue. @PEJasp Are cables same manufacturer? as you had no problem.

Dissapointing that this may be a RAM issue as we pay extra for dolby atmos via puck.

they are exactly the same I bought two of these in the same order:

For reference, I had this issue only with Atmos content was super annoying for quite a while, but everything else worked well. I have it set as passthrough and the decoding is done in a sonos arc.

[gpb156]

Good to hear. I am also using passthrough so that LG soundbar handles the decoding. Maybe I'll just get another matching cable!

I'll post if this is succesful.

So having had identical cables for the last couple of weeks I have had just a couple of drop outs on Dolby Atmos material. Deinitely an improvement, seems to be the best solution at the moment.

[PEJasp]

Good to hear it's improved.

i seemed to have a long period of no drop outs but now i get a very infrequent one like once an evening or every other evening.

not perfect but much improved.

lets hope sky fix it completely

I have the exact issue. My setup is a Bose Soundbar 600 with Bass Module. Had a conversation with Sky about the issue and they sent me a replacement puck which is no better.

I have HDMI 2.1 cables and the eARC channel on my TV is also HDMI 2.1.

I've tried Passthrough on the Soundbar > Passthrough on the TV > Soundbar

Auto on the puck > Passthrough on the TV > Soundbar

Auto on the puck > Auto on the TV > Soundbar

I find that I have less dropouts when letting the puck do the audio decoding but frequently have lip syncing issues.

Passthrough seems best but has drop outs frequently. Football is like a lottery as to what sound quality i'm gonna get.

Interesting to hear same issues with replacement puck. Maybe this is just a hardware issue with the puck that can't handle stream rate of Dolby atmos. I also have audio pass through to the soundbar, as you mention if puck does the decoding you wil have sync issues. The only other change I made was a wired ethernet connection hoping for a faster and more reliable stream, however still the occasional drop out. But these have reduced significantly after changes as discussed.
