Description:

Alsa plugin a52 doesn't work with ffmpeg version 1.1 or higher. Specifically encoding to ac3 inside a52 fails, probably due to changes in ffmpeg. Error message is:

[ac3_fixed @ 0x18daf20] Specified sample format s16 is invalid or not supported

In result there is no sound. Alsa fails to encode sound to ac3 and therefore pulseaudio fails to open alsa-sink. When I downgrade ffmpeg to version lesser than 1.1 it works.


Steps to reproduce:

Configure a52 in /etc/asound.conf and try running speaker-test or aplay.

Does a recompile help?

I tried to compile git HEAD version of alsa-plugins but it fails. I will recompile alsa-plugins with makepkg this evening and let you know.

Horay! I just build package alsa-plugins from latest tag 1.0.27 which has been published yesterday and plugin a52 works again like a charm.
