Public bug reported:
New install of 20.04.1 on 1/31/2021 onto MacBookPro
The "startup tone" plays when I start or re-start my computer.
When I enter my password and login to my computer I expect to go to the
audio settings, test the sound, and have the sound test work. I expect
to hear media played back through my web browser. I expect to hear sound
from my headphones or internal speakers.
The actual behavior is that I am unable to hear sounds from my internal
speakers or through headphones.
Steps to troubleshoot (all cmd line steps performed as root):
- checked sound not muted, system settings set correctly via cmd line
- performed sound test with headphones and external speakers.
- uninstall/reinstall/reload alsa
- apt-get remove timidity
- add snd-hda-intel.dmic_detect=0 setting to boot config
I tried these steps using various tutorials from users having similar
problems, and performed restarts after install/uninstall, reload of
software, or config change.
