After installation of snapshot 20201014 via zypper dup I have no more sound. I Use KDE
Sound card is a Xonar DGX and is recognized.
# cat /proc/asound/cards
0 [DGX ]: CMI8786 - Xonar DGX
C-Media Oxygen HD Audio at 0x7000, irq 27
# cat /proc/asound/modules
0 snd_oxygen
The driver is loaded and the card is found by aplay

When I test the sound I receive an error
# aplay -vv /usr/share/sounds/alsa/test.wav
ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection refused
aplay: main:830: audio open error: Connection refused
Any Hint?
