Hey Georg, I have updated my to raspios since last time : Debian GNU/Linux 11 (bullseye). It comes with : - pulseaudio 14.2 - GStreamer 1.18.4 Is it also too old ? I was hoping to avoid installing pulseaudio from source. If so, I will give it a try... ++ Jack Le dimanche 13 février 2022 à 17:05 +0100, Georg Chini a écrit : > On 13.02.22 16:57, corbeille wrote: > > Hello, > > > > I did some additional tests. > > And it seems the problem occurs when I have a second null sink. > > With > > only one null sink, I don't have any problem.
