Check if the GStreamer libav plugin is installed…
zypper se -si gstreamer-plugins-libav
Also check if GStreamer has an E-AC3 decoder available…
gst-inspect-1.0 | grep -i eac3
Please post the output of both commands.
For reference, on my SR system I get
~> gst-inspect-1.0 | grep -i eac3
libav: avdec_eac3: libav ATSC A/52B (AC-3, E-AC-3) decoder
libav: avenc_eac3: libav ATSC A/52 E-AC-3 encoder
typefindfunctions: audio/x-ac3: ac3, eac3
Check zypper se -si ffmpeg libavcodec and report back.
Edit: Just noitced your mention of SMPlayer…it is a front-end for mpv, and that uses FFmpeg’s decoding libraries, including libavcodec, for formats such as E-AC3. So gstreamer not actually relevant here.
here is

pla@plaST-slowroll:~>
the difference are evident with your setup
typefindfunctions: audio/x-ac3: ac3, eac3
libav: avdec_eac3: libav ATSC A/52B (AC-3, E-AC-3) decoder
libav: avenc_eac3: libav ATSC A/52 E-AC-3 encoder
typefindfunctions: audio/x-ac3: ac3, eac3
Since you’re currently using the openSUSE FFmpeg 9 packages, I’d suggest installing FFmpeg from the VLC repository instead. That’s the FFmpeg 8 stack I’m using, and it provides the E-AC3 decoder.
See: https://en.opensuse.org/SDB:Installing_ffmpeg_from_the_VLC_repository
As the VLC repo only offers “ffmpeg-8” currently, you’ll need to use the --oldpackage flag…
sudo zypper in --from vlc --oldpackage ffmpeg-8
See how that goes.
there is not repo for slowroll, can I use the one for tumbleweed?
https://download.videolan.org/SuSE/Tumbleweed/
Yes, that’s what I am using. Should be no issue for this use case.
the repo was also in myrlyn>community-repos and ffmpeg-8 offered as package
installed via myrlyn the repo
the name of the repo was VideoLAN so I changed in the command
I did this selecting solution 1
and now smplayer play sound
maanythanks!! 
pla@plaST-slowroll:~> sudo zypper in --from VideoLAN --oldpackage ffmpeg-8
Refreshing service 'openSUSE'.
