Comment 52 for bug 1888598

We have an OEM bug which is similar to this one. I don't know if it is the exact same issue as this one, to fix that issue, I did some change in the module-card-restore.c, and If users is on the ubuntu Linux 20.04, please try this testing-pulseaudio (try 2 hours later since the building process has not finished yet): https://launchpad.net/~hui.wang/+archive/ubuntu/pa-testing

steps:
rm ~/.config/pulse/*
sudo add-apt-repository ppa:hui.wang/pa-testing
sudo apt-get update
sudo apt install pulseaudio
reboot
start to test.
