I have "Dummy Output" in my sound settings. I am fairly new to Linux, however am fairly computer literate. I LOVE Linux, so I would really prefer a solution as opposed to going back to Windows which I hate.
My sound card is a HDA-Intel "Realtek ALC3235".
Also, I have a touch screen (which I don't really use, I use the keyboard) laptop and with one of the upgrades came the problem of the mouse jumping all over randomly while typing. Anyone have a solution for that?
Found this bug listed https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1801538
I tested the following command and the result was instant. Everything fully restored.
systemctl stop timidity.service
Then went ahead and disabled. Will see what happens.
I ran into this problem after updating from 18.04 to 18.10. I tried restarting PulseAudio with
killall pulseaudio; rm -r ~/.config/pulse/* ; rm -r ~/.pulse*
and
pulseaudio -k
but that didn't seem to do anything. I eventually started up the pavucontrol GUI, which I believe was also showing Dummy Output as the device on the first tab that opened up. However, I went to the "Configuration" tab and found that the "Profile:" drop-down for "Built-In Audio" was fully populated. (I don't entirely recall what it was initially showing. It could have been "Dummy Output", "None", "Off", or anything similar. The option disappeared after I picked a "real" device.)
For the way my laptop is set up, I went all the way to the top and picked "Analog Stereo Duplex" as the profile, which is probably what you want. There were also a whole bunch of HDMI output options for the video output on my laptop's mini USB-C dock.
I suggest you to install a clean version of Ubuntu 18.10. Remember to click on desktop version
