I don't know about module-detect, but module-hal-detect will by default use just two channels. The default is configured with default-sample-channels in daemon.conf. If you still don't have progress, I would think that one possible solution would be to run those programs that need AC-3 passthrough with pasuspender (e.g. start mplayer with command "pasuspender mplayer") and configure the programs to use the spdif device directly. > If I used anything besides nothing or channels=2, I don't get any audio. Here I'm a bit confused - what do you give that parameter to? I thought you were talking about module-detect, but it doesn't accept that parameter. -- Tanu Kaskinen _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@mail.0pointer.de https://tango.0pointer.de/mailman/listinfo/pulseaudio-discuss
