Pulse Audio Started but no sound

[basementmedia]

Hello,

I suddenly have the problem that the PulseAudio to Jack Bridg doesn't seem to work anymore.
Cadence shows that Pulse Audio is running but no sound is coming.
When I display the Pulse Audio Mixer (means the normal volume control of the system) I get a graphical signal that the sound of the active application (e.g. Audacity) is changing, but I don't hear any sound.

When I open Ardour, I hear a sound (since Ardour plays the sound directly to my Firewire interface via FFADO).

I didn't change anything on my system (no new installations or the like) and the problem came suddenly ;-(

Does anyone have a hint for me where the problem could be or what I could try to find the error?

Thank you for your support.

Best regards

Daniel

Sorry, I just fixed the problem.
Apparently it was due to the fact that I had connected my TV to HDMI for a short time and then it was automatically set as the audio output device.

To fix it I went to the Pulse Audio Mixer, there to the tab "Output devices". There I removed the mute circuit.
