since the update I have no audio. No sounds on the computer or on Bluetooth speakers. The only output for audio I can choose is "Dummy Output".
On my keyboard the sound volume buttons no longer work, and I have no toggle for sound volume anywhere to be seen.
My laptop is an i5 Fujitsu laptop.
Edit: The first fix here: https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.html worked to the extent that my output devices and buttons to control the volume showed up. However, I still have no audio, not on the computer or on Bluetooth speakers.
Edit2: my soundcard is Haswell-ULT HD audio controller, Intel Corporation
