I have two devices for sound output:

enter image description here

Always when I plug in my headphones or external speakers - for whatever reason - the Digital Output gets selected which means in this case that I have no sound at all.

How can I keep the from system switching the device?

  • Okay I just had luck by adding blacklist snd_hda_codec_realtek, blacklist snd_hda_intel and blacklist snd_hda_codec to the blacklist /etc/modprobe.d/blacklist.conf as described here: http://askubuntu.com/questions/270312/disable-hdmi-sound-out-for-decrease-power-consumption – Stefan Falk Feb 27 '14 at 18:48
