Bug Description

After upgrading to the 18.10 development version from 18.04 only "Dummy sound" is shown. The speakers are not recognized, but plugging headphones works. The system was working well in 18.04.

With:

sudo alsa force-reload

the speakers start to be shown in the sound system parameters and sound is reproduced through the speakers normally.

I've changed the title because according to lspci the audio device is actually Intel Corporation Sunrise Point-LP HD Audio (rev 21)

Thanks! The problem is:

ii timidity-daemon 2.14.0-8 all runs TiMidity++ as a system-wide MIDI sequencer

which makes this a duplicate of bug 210472.

Please just uninstall timidity and timidity-daemon.
