Bug Description

Binary package hint: pulseaudio-module-raop

When connected to a network on which it finds an Airport Express unit, pulseaudio goes nuts and constantly talks to it, at about a 1.5MB data rate - even though I haven't connected to it, or done anything.

If I remove the pulseaudio-module-raop package and restart pulseaudio, it doesn't talk to it anymore, but this is a suboptimal solution - I might want to connect to it and play music.

Yes, this is known by the pulseaudio upstream developers. Work needs to be done on making the raop support code run more cleanly and less crasy/flaky. The only real work-around at the moment is to enable/disable the raop plugin in the config files for pulse, found in /etc/pulse.

this bug prevails in oneiric, it's really a pity because it makes the whole plugin/module unusable.

As I've suggested a gazillion times, the fact that the ROAP module is loaded when the package is installed is NOT what I intended as the upstream author and maintainer of this code. Please remove it, I'm sick an tired of supporting users coming to upstream channels because of downstream modifications. The ROAP module is not perfect code and it WILL prevent any Mac or Windows machines using the RAOP device when the module is loaded. It does not behave well and is not a good citizen. If you wish to make the module loaded by default then ensure you employ someone to work on the code to improve it before you do so.

The module can and should be loaded via paprefs. This gives the user the choice. I believe you also need to update paprefs for the new PA 1.0 you shipped as I've heard user reports that it's currently broken.

If you wish for the module to be turned on by default when the package is installed then change the gconf schema, do not hack the default.pa.

It was only added to default.pa because some users who were not aware of the consequences suggested it. Do not act on the suggestions of users without researching the problem and asking the upstream people. We do things for a reason, please respect this.

Colin, apologies for the unnecessary (and wasted) effort on your part. Is removing our patch to load module-raop-discover the right way to go for Ubuntu 12.04 LTS, then?

@Coling: By the way, it seems that it's not a too old paprefs version that makes the network settings insensitive but this bug: https://bugs.launchpad.net/ubuntu/+source/paprefs/+bug/829051

It seems that someone inadvertently removed not just the RAOP loading but also the Zeroconf loading. This results in native PA remote sinks no longer being detected by default, which is not desirable.
