Java audio Clip cannot be closed when using Linux PulseAudio

由 送分小仙女□ 提交于 2019-12-06 08:22:36
问题 I'm trying to play a sound in a Java application but the application never actually terminates because the PulseAudio Eventloop thread is left running even after trying to close the Clip instance used for playing the sound: import java.io.File; import java.io.IOException; import javax.sound.sampled.AudioFormat; import javax.sound.sampled.AudioInputStream; import javax.sound.sampled.AudioSystem; import javax.sound.sampled.Clip; import javax.sound.sampled.DataLine; import javax.sound.sampled

pactl called from systemd service always reports “pa_context_connect() failed connection refused”

I've setup a systemd service file to perform some pactl operations at system startup for a test process. While the commands work fine when performed from a terminal I always get "pa_context_connect() failed connection refused" when running the same script from the systemd service by starting the service. I'm also using the 'User=' directive in the service file to ensure that the auto-login user matches the user used to run the service commands. I've read that this is somehow related to the pulseaudio session not being valid in the environmentless context of the systemd service but I haven't

How to redirect from Audio Output to Mic Input using PulseAudio?

由 好久不见. 提交于 2019-11-30 11:32:11
I'm working on a mobile app for Maemo/MeeGo and Maemo uses PulseAudio. I want to play a mp3 to caller (and cancel the mic when doing it, and not to listen caller, everything should be done on background), to do this, I have to redirect Audio Output from a certain (if not possible, all) app, fake it as a Input and make Phone app use it. On my Ubuntu PC, I did it with pavucontrol. I created a NULL sink, then: Audio Output (from Amarok) --> to NULL Output Skype Input <-- NULL Output Skype Output --> NULL And It worked, Amarok played the music and It was streaming to Skype, without playing it to

How to expose audio from Docker container to a Mac?

I know it's possible by using pulse audio on a Linux host system But paprefs is built for linux not mac. The Docker-for-Mac VM doesn't have any sound passthrough device, so there isn't anything that you could take advantage of from that angle. By contrast, a virtualbox or vmware fusion VM does have the ability to do passthrough audio. I was able to get pulseaudio installed and working on OSX with the following command: brew install pulseaudio I was able to verify this worked by running the following, hearing sound come out of my speakers: paplay cockatiel.wav My next step is to find an image
