I have no sound on Ubuntu 14.04 since about a week now, but Bluetooth speaker and Bluetooth headphones work. I must have been an update doing it, because a friend of mine has the same problem with an identical laptop — while another friend with the same laptop has no problems, because he does not believe in doing updates.
The Sound Settings shows Dummy Output only.
Laptop: Dell Inspiron 15 3551
Does anybody know anything about this problem?
This question was regarding the original installation on a Dell Inspiron 15 3551 (64bit). I have another 14.04 installation on an older 32bit laptop, which was unaffected — if that is of any interest to anybody.
Since I am now organising my new 18.04 installation, the question is no longer relevant to me. And since no solution was found, anybody that thinks it appropriate is welcome to delete this post. I don't believe I would have the authority to do so. Thank you.
