Bug#972689: Some more details
I got an answer from pulseaudio-disc...@lists.freedesktop.org. The suggestion ist to run the script https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/raw/master/src/utils/pa-info and open a bug at PulseAudio. The interesting thing is that this script should be part of the package pulseaudio-utils, but this package is installed and the script is not existant? # apt-file search pa-info pulseaudio-utils: /usr/bin/pa-info So i downloaded the script and the result of it is attached. A corresponding bug is opened now at PulseAudio https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1021 > pulseaudio_ps_do karsten 3312 0.1 0.3 1734412 25964 ?

Bug#972689: Some more details
After the last experiments and rebooting this time there is a new situation without sound. The soundblaster card is now card 2 and ALSA is working with aplay -D hw:2,0 /usr/share/sounds/sound-icons/canary-long.wav As you can see in the screenshot the card has been found by pulseaudio, but when it is moved up to the first position it cannot be used when you click on test. The error says that the device cannot be selected. What is going on with PulseAudio here? I tried to contact pulseaudio-disc...@lists.freedesktop.org with this problem and linked this bug ... $ aplay -l Liste der Hardware-Geräte (PLAYBACK) Karte 0: SB [HDA ATI SB], Gerät 0: VT1708S Analog [VT1708S Analog] Sub-Geräte: 0/1 Sub-Gerät #0: subdevice #0 Karte 0: SB [HDA ATI SB], Gerät 1: VT1708S Digital [VT1708S Digital] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 Karte 1: NVidia [HDA NVidia], Gerät 3: HDMI 0 [HDMI 0] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 Karte 1: NVidia [HDA NVidia], Gerät 7: HDMI 0 [HDMI 0] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 Karte 1: NVidia [HDA NVidia], Gerät 8: HDMI 0 [HDMI 0] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 Karte 1: NVidia [HDA NVidia], Gerät 9: HDMI 0 [HDMI 0] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 Karte 2: AudioPCI [Ensoniq AudioPCI], Gerät 0: ES1371/1 [ES1371 DAC2/ADC] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 Karte 2: AudioPCI [Ensoniq AudioPCI], Gerät 1: ES1371/2 [ES1371 DAC1] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0

Regarding the Debian documentation https://wiki.debian.org/PulseAudio Setting "autospawn = no" in /etc/pulse/client.conf has no effect! I did also try cp /etc/pulse/client.conf ~/.config/pulse/ pulseaudio --kill You always have this process "00:00:00 /usr/bin/pulseaudio --daemonize=no" I tried to delete the configuration in ~/.config/pulse/ without no effect. When you rename /usr/bin/pulseaudio then pulseaudio cannot start but you don't have any sound in KDE! What must be done to get rid of pulseaudio and to get direct sound with ALSA? When you try to remove the package there are to much dependencies: # apt-get purge pulseaudio Paketlisten werden gelesen... Fertig Abhängigkeitsbaum wird aufgebaut.

Bug#972689: Some more details
In the Multimediasettingsof KDE you can see that the soundblaster card is greyed out - why? This is the card that is working in ALSA, but only sometimes with pulseaudio in KDE. I tried to create an installation of Debian Bullseye, but this is not possible too ... https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=972820
