According to #13 ~ #16, your sound card is registered successfully. But ubuntu 18.04 doesn't support ucm conf for this sound card yet, as a result the pulseaudio and gnome layer doesn't find your sound card.
If you want to have a try, please follow these steps: cd /tmp/ git clone git://git.alsa-project.org/alsa-lib.git sudo mv /usr/share/alsa/ucm /usr/share/alsa/ucm-ori sudo cp -rf alsa-lib/src/conf/ucm /usr/share/alsa/ reboot check if audio works under gnome To restore original ucm: sudo mv /usr/share/alsa/ucm /usr/share/alsa/ucm-latest sudo mv /usr/share/alsa/ucm-ori /usr/share/alsa/ucm reboot -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1831301 Title: sound doesn't works in both kernel. no one cards is recognize by system- Status in linux package in Ubuntu: Confirmed Bug description: .
