No more sound after snapshot 20201014

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?

PulseAudio is not running, and you have PULSEAUDIO_SYSTEM set to yes in /etc/sysconfig/sound.
This is the setting you can change in YaST2 / Sound / Other / “PulseAudio Configuration”.
If you don’t intent to use PulseAudio, make sure this is off
Otherwise check if PulseAudio is running:

systemctl status pulseaudio

Start and enable PulseAudio:


systemctl enable pulseaudio
systemctl start pulseaudio

Review the troubleshooting guide
https://en.opensuse.org/SDB:Audio_troubleshooting

FWIW, with openSUSE, PulseAudio status can be checked using…

sudo setup-pulseaudio --status

Enable with

sudo setup-pulseaudio --enable

and disable with

sudo setup-pulseaudio --disable
