Knotify locks the sound and no other applications can use it. So I have to kill knotify to be able to use sound again :

lsof /dev/snd/pcmC0D0p
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
knotify4 813 sheridane mem CHR 116,4 1339 /dev/snd/pcmC0D0p
knotify4 813 sheridane 17u CHR 116,4 0t0 1339 /dev/snd/pcmC0D0p

pacman -Qo /usr/bin/knotify4
/usr/bin/knotify4 appartient à kdebase-runtime 4.8.0-1

Thanks.
This task depends upon

I would like to change the severity to normal or high.

What's your sound device configuration in KDE? I guess it's configured on your system in a way that it bypasses dmix or any sound daemon, which causes problems like these.

It's using ALSA directly.

Happens to me too (confirmed with lsof) with or without
pulseaudio installed on the system. Notice that this is
also reported to https://bugs.kde.org/show_bug.cgi?id=281961.

Some additional notes:

- After login volume control does not show up in the KDE panel.
- If I kill knotify4, it will respawn, volume control shows up
and everything works nice and smooth.
