Public bug reported:
This problem seems begin from ubuntu 19.04.
Sometimes after login, headphone outputs white noise only, speaker does
not work.
Nothing can play music with the noise.
The noise is impossible to stop except POWEROFF the PC.
Rebooting cannot stop it, the noise keeps even reboot into Windows OS.
In Windows OS, headphone still white noise, after unplugging headphone, the
speaker does not work, too.
It works fine in Windows OS.
If I remove pulseaudio, only use ALSA. It also works stable.
(But now... firefox do not support ALSA, chromium-snap do not support ALSA
too...)
It seems pulseaudio killed the sound card...
The problem appears randomly, I do not know how to reproduce. sorry...
