Hi,
I'm trying to change Pulseaudio default audio card start in a shell
script, but I don't know what I must do.
There is not really such a thing as a "default" audio card in PA. The
term we use is usually "fallback" as this more accurately represents
what it means. PA remembers each application's preferred device. Thus if
you play something in e.g. mplayer and we've never seen an mplayer
stream before, we will use the "fallback" device and then save that
choice in a little database. The next time mplayer tries to play
something, we first look to see if we've got a preferred device for
mplayer and if so, we use it. In this second case the "fallback" device
is not consulted.
So, from the command line you can indeed set the fallback sink via the
command:
pacmd set-default-sink index|name
But this will only really change the "fallback", e.g. all apps that have
played before will continue using that device. If you want to change
these previously stored preferences, the only tool that supports that
currently is the gnome-volume-control. pavucontol does not update the
individual application preferences either.
Hope that clarifies things.
