Hi, my Sky Stream keeps losing the voices/sound for about 2 seconds at a time. When it happens, my TV flashes up the HDMI information banner saying “HDMI 1 / Stereo Dolby Digital Plus / 3840 x 2160p”, as though the HDMI signal or audio format is being detected again.
I have already checked and pushed in all the cables, unplugged/restarted the TV, and checked the settings before, but it is still happening. It happens while watching Sky through HDMI.
Can you please check whether this is a known Sky Stream issue, whether my puck needs replacing, or whether there is a setting/update problem with Dolby Digital Plus or HDMI handshaking?

I have moved your post to the Stream board as it's unconnected to Sky Mobile. Incidentally you haven’t contacted Sky by posting here. This is a customer ▶️ customer discussion forum where we try to assist other customers.

Have you tried changing the HDMI cable? I'd recommend a certified HDMI 2.1 cable - available from Amazon for under a tenner. This can often sort issues like this.

Have a look in this forum about a firmware upgrade qs038. There are lots of other people having the same issue

How do I check if my Sky Stream puck is on QS038? Can I force the update, or do I just leave it in standby overnight?

Mine says QSE038.010.00P. Is that an older QS038 build? I’m still getting the 2-second audio drop-outs and the TV flashes up HDMI / Dolby Digital Plus / 3840x2160p when it happens. Should my puck update to QS038.023.00P automatically, or does this need raising with Sky?

@Nikkilt51 As advised you're on the current version listed as it depends on puck type, no you can't force an update, nor can Sky.
There is nothing to update.

Re: TV keeps showing that HDMI 1 / Dolby Digital Plus / 3840 x 2160p banner . Tv freezes for about 2
Thanks. So if there’s nothing to update, what should I try next please? I’m still getting 2-second audio drop-outs, and when it happens my TV flashes up HDMI / Dolby Digital Plus / 3840x2160p. Cables have been checked and the TV has been restarted. Could this be a Sky Stream puck fault or a Dolby Digital Plus/HDMI issue??

@Nikkilt51 Try using Passthrough for Audio on the stream puck audio settings

Hi, the puck/stream has many issues, but this is not a known one.
I would suggest using a different HDMI port on your tv.
Try a different HDMI cable.
In the puck settings, you can change the sound output type. Try changing these.
The fault process will be one step at a time, until you localise or disprove it.
For example, replace the cable. Does it still happen? Yes = not the cable, No = faulty cable.
