I'm running Linux Mint 17.3. When I'm using pulseaudio my external sound card ("Sandberg", in pulseaudio control center it is shown as "CM106 like sound device" ) wokrs perfectly, however the jack server can not be started for this card. I'm trying to start jack server from QjackCtl, while pulseaudio is killed (autospawn also is changed to no).
The error message:
