[Alsa-user] Limited access to capture source

[<ce...@op...>]

Hi all,

My need is:

Have a linux system (Debian) with automatic voice recording (when user log
in).
Users should not have impact on that process - do not mute mic, do not
change capture source nor recording level.
However audio playback should be unrestricted for all users.

Actually I use ffmpeg with alsa input but this solution blocks pulseaudio.
:(


Should it be done on alsa or pulseaudio level and how ?


Regards.
Tom.
