AC-3

[hwk]

Hi,
I added AIMP to a new PC and copied the link (via Ctrl_U) from my old PC to the new one. The display in the playlist window is the same as on my old PC. When I click on play I get the error msg:

I have "Allow system decoders usage" selected, it is a Dolby 5.1 stream.
Any help appreciated, Hans

It seems the station uses Enhanced AC-3 codec that is not supported by AIMP.

I have "Allow system decoders usage" selected

Windows 11?

Beginning with Windows 11, version 24H2, the AC-3 codec is no longer included with Windows.

You can try to install https://apps.microsoft.com/detail/9nvjqjbdkn97 or some third-party codec pack.

It doesn't play on Manjaro Linux with "Allow system decoders usage" enabled too.

   ~  gst-inspect-1.0 | grep -i eac3                                                                                 ✔
libav:  avdec_eac3: libav ATSC A/52B (AC-3, E-AC-3) decoder

Strawberry and VLC can play it w/o any issues.

Update: EAC3 stream works on my Windows 10 with AIMP 6 build 3036 and "Allow system decoders usage" enabled. It might be so cause I have installed K-Lite Codec Pack.
