TV keeps showing that HDMI 1 / Dolby Digital Plus / 3840 x 2160p banner . Tv freezes for about 2 sec

Nikkilt51 — Tue, 02 Jun 2026 08:52:03 GMT

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?

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.

@Nikkilt51

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 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?

@Nikkilt51 You can't force updates, depending on your puck will dictate the software version number, updates are pushed automatically.

These are the current software versions depending on puck type https://www.sky.com/help/articles/sky-software-updates

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.

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.
