FYI: I tested again with a current Ubuntu Installation, Lubuntu 15.04, Kernel 3.19.0-21-generic #21-Ubuntu SMP (same Asus Notebook as noted above). The good news is the "switching bug" disappeared. The bad thing is that there is still no (speaker) sound yet, not with the installation default and not with manually trying the entry working for me in an earlier ubuntu version - options snd-hda-intel model=laptop-eapd position_fix=1).
Here is a recent alsa-info: ALSA information is located at http://www .alsa-project.org/db/?f=dd668e30fbdc329986902f48d7aa9229a17281e6 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1316156 Title: speakers audio won't work - pavucontrol is switching continually between speakers and headphones Status in ALSA driver: Unknown Status in alsa-driver package in Ubuntu: Confirmed Bug description: The port is continually switching between Speakers and Heaphones and no audio is outputting from the speakers. I have tried various distributions and have found that this problems is NOT present in Ubuntu 11.04, 12.04, 13.04. I have not tried 11.10, or 12.10. But have found 13.10 and 14.04 to show this identical problem. My main concern is for the 14.04 LTS version I am currently using. - I tried regulating the audio from alsamixer -by disabling auto-mute in alsamixer i managed to stop it switching from one port to the other. Still, no audio from speakers (only a regular and low-volume BUMP comes out) - I tried modifying the /etc/modprobe.d/alsa-base.conf file. Since i could not find my pc (Packard Bell EasyNote MX45) in the alsa-configuration list, i have tried using only the audio boards main info as referral (Intel HDA AD1986A NM10/ICH7). Thus i have added to the alsa-base.conf the following and rebooted after trying each and every new line (added only once per try, not all of them together). -options snd-hda-intel model=laptop -options snd-hda-intel model=laptop-eapd -options snd-hda-intel model=3stack -options snd-hda-intel model=generic - Also tried the position_fix quirking suggested on the ubuntu documentation pages -options snd-hda-intel position_fix= 1 -options snd-hda-intel position_fix= 2 The audio outputted from the speakers kept being a regular BUMP and nothing more, regardless of the input.
