Thanks for reporting upstream. I'm also experiencing non-working a52 encoding with the libasound2-plugins package shipped with debian (1.2.5-2). On my system, the plugin outputs a digital 2-channel signal without any sound instead of the expected 6-channel AC3 encoded stream. After some researching I found that the main problem is not the configuration files, but changes in the libavcodec encode API that were not handled correctly by the a52 plugin. There were multiple commits in upstream alsa already to fix the issue (see for example here: https://alsa-project.org/wiki/Changes_v1.2.5.1_v1.2.6 ). So I assume that the current version (1.2.5) is just broken with respect to the a52 plugin. I'm looking forward to a new release of 1.2.6 (or newer) to be included in debian, which should hopefully fix the issues again. It would be great if a maintainer could upgrade the debian alsa packages to latest upstream (see also this request https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1001697 ) Best regards, Stefan
