Title:
speakers audio won't work - pavucontrol is switching continually
between speakers and headphones
Status in “pulseaudio” 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.
