I have been trying to solve this problem for many years. I just did a clean install of Ubuntu 14.04 hoping that the problem would be fixed. Unfortunately most of the information on the Ubuntu Community Wiki warns that it is outdated so I am turning to askubuntu for guidance.
I have ans Asus K52F laptop and the in-built speaker don't work. I have tried many fixes for this problem but none of them have worked. Most of them suggest changing a line in
alias snd-card-0 snd-hda-intel options snd-hda-intel model=dell-m4-1 enable_msi=1 # this line in Ubuntu 14.04
to something like:
options snd-hda-intel model=generic # or options snd-hda-intel model=asus
I have tried a number of models but none of them have worked. Additonally, many of the solutions suggest making sure the
alsamixer are working. I notice that my interface for
alsamixer seems to have less options than others, for example, there is no speaker, front or left, or headphone controller. Here is a screenshot of what I see in
As you can see the card is HDA Intel MID and the chip is Intel IbexPeak HDMI.
Should there be any other outputs that could be valuable to troubleshoot this problem, let me know in the comments and I will update the question.
