I got annoyed by the extra output (welcome message, prompt) of pacmd when using the program for scripted testing. This patch series changes the default behavour of the daemon cli to non-interactive mode (i.e. no welcome message, no prompt). Interactive mode can be requested by sending "hello" as the first command. pacmd tried to figure out if interactive (connected to a terminal) or non-interactive mode is sensible and sends "hello" if needed. Thanks to everybody for discussion!
