[BUG] Mixing All Speakers option shows only audio outputs added before panon started #60

Open marekvospel opened 3 years ago

Desktop (please complete the following information):

Describe the bug Panon only detects new devices when it starts. If a bluetooth / jack / different audio output device is connected while panon is already running, panon won't react to that output stream.

Steps to reproduce

rbn42 commented 3 years ago

It is possible to add this feature (or fix the bug), as far as panon can capture the event when a new device is connected. I believe "org.kde.plasma.private.volume" can capture this event, with its "PulseObject.Ports.length" I guess. But I cannot find its documentation on kde.org to make it work.

Specifically, I see Zren using these variables in volumewin7mixer. PulseObject.channels: https://github.com/Zren/plasma-applet-volumewin7mixer/blob/e66e2918bc7572c189f86c4367ae6f21db7b5af0/package/contents/ui/MixerItem.qml#L28 PulseObject.ports: https://github.com/Zren/plasma-applet-volumewin7mixer/blob/e66e2918bc7572c189f86c4367ae6f21db7b5af0/package/contents/ui/MixerItem.qml#L157 But I am not able to import them into panon. conlose.log() shows theses variables are undefined. Does anyone has a clue? What is the correct way to use these APIs?

Hi @Zren, could you please give me some advice? or a link to the documentation of this PulseObject variable. Thanks.

SinkModel, SourceModel etc, inherit AbstractModel, which is an "array" where the child items only have one property, which can be referenced as model.PulseObject in a ListModel, or just as PulseObject.
