All other functions seem to work correctly. This issue only applies to combined sinks in our setup. A more optimal solution would be to adjust PulseAudio to not introduce the delays in the first place. But I guess these delays heavily depend on the computers performance.

In the future, as a workaround, I might add setting of delays for separate sinks. Currently there is no way to correct this. This leads to noticeable delays between the different speaker outputs. PulseAudio in our application seems to not be able to process streams on combined sinks correctly. The results is an easily configurable PulseAudio via Java. There is no API and all information has to be parsed from PulseAudio output.

While the resulting code is relatively short, the task of controlling PulseAudio is not trivial. We use it in EVA to stream music from passenger smartphones to their seat, by employing a mini-FTP-server in our smartphone app.Īdditionally, some helper functions are available, allowing to find the correct sink number for the sound card, or sinks by inputs, for example. The latter implements a very simple music streaming. I further added the option to play local files or, via wget and a named pipe, internet streams (e.g. Inputs (such as media players) can be assigned to any sink. Sinks to /dev/null can be created, soundcards can be discovered, combined sinks between different soundcards can be created, and so on. Essentially PulseAudio is a large mixing console.Īll these functions can be controlled with PulseAudioJava. Further, sinks can be combined to play identical output. For each sink, the volume and inputs can be controlled separately. The tool described here allows us to do exactly this. For EVA, we wanted to be able to control PulseAudio inputs and sinks from our Java framework, such that we can start playing music from different sources on different seats. We use PulseAudio to manage the input from internet radio, as well as streams from passenger smartphones and control which output (or seat) each input is directed to. In our electric taxi EVA we have stereo speakers on every seat. PulseAudio also provides tools to manage these inputs and outputs (called sinks). soundcards, headphones) connected to the computer. It controls all audio to be played and all audio playback devices (e.g. It can optionally handle multimedia keys for controlling the audio volume.

The Xfce PulseAudio Plugin is a plugin for the Xfce panel which provides a convenient way to adjust the audio volume of the PulseAudio sound system and to an auto mixer tool like pavucontrol.

I am not familiar with sound configuration. I did not perform any other action.įrankly, I think I need to modify some config files or something.I did the pulse audio sound tests and they do indeed output.

I did install the pulseaudio sound server including the esound option. New out of the ground this evening, upgraded to Sid.

And I have performed a full system restart. It brought down two more dependencies and reported all was ok. I need assistance please to make this work in Debian Sid, updated as of 21:53 tonight, US/Mountain (GMT-7).
