concerns: Linux Mint 18 Cinnamon 64bit Kaffeine used for DVB-T TV. It is like that: VLC (for example) and Kaffeine both are running. If I change now the volume in VLC, the volume ruler of Kaffeine (in pulseaudio) changes with the next programstart or station switch of Kaffeine to the volume level of VLC. As well VLC picks up after program (re)start the volume level of Kaffeine (to check in pulseaudio). This becomes important when I wish different sound levels for both apps: I want to listen to TV (Kaffeine) and watch simultaneous a video silent in VLC. Yes, that happens, TV to me is often like radio listening..... :). Reproducible: Always Steps to Reproduce: first: 1. start Kaffeine (DvB-T) loud 2. start VLC (silent) 3. in Kaffeine switch to another station or restart Kaffeine second: 1. start VLC (silent) 2 start Kaffeine (loud) 3. Restart VLC Actual Results: first: Kaffeine gets as silent as VLC second: VLC gets as loud as Kaffeine Expected Results: first: Kaffeine keeps its volume level second: VLC keeps its volume level Irritating to me was that In Kaffeine the volume ruler shows no effect on the Kaffeine-volume ruler in pulseaudio although the volume changes recognizable. In contrast the volume ruler of VLC works synchronized with the one in pulseaudio. ???? I cannot give the version of Kaffeine cause now I installed Mint 17.3 64bit on my PC (here is no problem with the volume levels). But it is the version that comes with Mint 18 Cinnamon 64bit.

But it is the version > that comes with Mint 18 Cinnamon 64bit. That sounds to be an issue with pulseaudio. Kaffeine (version 2.x and 1.3) uses libvlc for audio/video output. The logic to set volume there is really simple. It just calls libvlc, and let it do its magic: void VlcMediaWidget::setVolume(int volume) { // 0 <= volume <= 200 if (libvlc_audio_set_volume(vlcMediaPlayer, volume) != 0) { qWarning("cannot set volume %i", volume); } } Maybe PA on your distro is not capable of distinguish VLC from a libVlc-based application and it is doing the wrong thing there.
