Technical Summary – Audio Issues on Dreambox Two (Amlogic / DreamOS 2.6)

We have investigated this in depth and the behaviour is consistent with the audio architecture of DreamOS on Amlogic-based boxes (Dreambox One / Two / Seven).

1. Why it worked “sometimes”

Audio appearing to work on several videos in a row is not reliable behaviour.
This happens when:

the selected stream is progressive (muxed audio+video), or

the pipeline never actually opens a real ALSA audio sink.

As soon as a true DASH stream with a separate audio track is played (e.g. Twitter/X, or some YouTube formats), GStreamer attempts to open ALSA directly.
On Amlogic DreamOS, ALSA is exclusively owned by Enigma2, so this fails.

After this failure, the pipeline often remains in a broken internal state, which explains why:

the same videos may later play without audio

behaviour appears random, but is actually state-dependent

This is expected and reproducible.

2. Why this differs from Dreambox 900/920

Older Dreamboxes (Broadcom-based):

had a different DVB audio pipeline

provided dvbaudiosink and looser integration between GStreamer and Enigma2

tolerated external audio playback in plugins

Dreambox Two (Amlogic):

has strict ALSA exclusive access

no dvbaudiosink

Enigma2 is the only valid audio owner

external audio playback is unsupported by design

This is a platform architectural change, not a plugin bug.

3. DASH with separate audio is not supported in plugins

On DreamOS Amlogic:

MoviePlayer cannot accept separate audio/video URLs

plugins cannot sync external audio

GStreamer audio playback conflicts with Enigma2

Therefore:

DASH (separate audio/video) is inherently incompatible

progressive (muxed) streams work reliably

Twitter/X will always break audio (no muxed streams)

4. Correct and stable approach

The only stable solution is:

hand over a single muxed stream to Enigma2’s MoviePlayer

or implement automatic fallback to a progressive stream when DASH is detected

This is exactly how stable plugins avoid audio issues on Dreambox Two.

5. Key conclusion

Quote

Audio “sometimes working” does not indicate partial support.

It indicates undefined behaviour until ALSA is inevitably accessed and fails.

For Amlogic DreamOS, this limitation is fundamental and unavoidable.

Look do not need to post to me what Ai say ...

Because my codes for youtube without using exteplayer3 is different than what AI say. Far away..

The codes I was sent to you as you mentioned works and now you said does not work and I see in log (Device 'default' is busy) again
this is stranger

Test and send log for all files ..

dniestre · Feb 9th 2026

The first two cause the enigma to restart, and in the last one there is no sound.

**fairbird** · Feb 9th 2026

1 and 2 test again please I need log important

stop enigma2

Code

init 4

start debug e2

Code

enigma2

then look the error and post it here

**fairbird** · Feb 9th 2026

Here more 2 files .. Test and send logs

dniestre · Feb 9th 2026

1 and 2 from post 2184

**fairbird** · Feb 9th 2026

Now send feedback of last update #2,187

Here more 2 files .. Test and send logs

With these two, it does not automatically return to the satellite channel. I have to select it manually.

**fairbird** · Feb 9th 2026

...

**fairbird** · Feb 9th 2026

The problem is alwasy the same (Device 'default' is busy)

I do not know what the other channel of audio can be enable as like all boxes ...

Only DreamOne and Two (amlogic) difference

Test this

**fairbird** · Feb 9th 2026

Test

and also from telnet do this after restart e2 (do not forget to send a.mp4)

Code

gst-launch-1.0 filesrc location=/tmp/a.mp4 ! qtdemux ! aacparse ! avdec_aac ! audioconvert ! alsasink device=hw:0,0

and

Code

gst-launch-1.0 filesrc location=/tmp/a.mp4 ! qtdemux ! aacparse ! avdec_aac ! audioconvert ! alsasink device=hw:0,1

and

Code

gst-launch-1.0 filesrc location=/tmp/a.mp4 ! qtdemux ! aacparse ! avdec_aac ! audioconvert ! audioresample ! pulsesink

and

Code

gst-launch-1.0 filesrc location=/tmp/a.mp4 ! qtdemux ! aacparse ! avdec_aac ! audioconvert ! audioresample ! alsasink device=dmix

and

Code

gst-launch-1.0 filesrc location=/tmp/a.mp4 ! qtdemux ! aacparse ! avdec_aac ! audioconvert ! amlasink

and

Code

gst-inspect-1.0 pulsesink

and send all output
