Hello Thank You for your assistance.
I installed 5.11 but no luck still. No sound and only "Dummy Output". I looked through my syslog and I found some references to alsa and sound. The syslog is too large to send but I have extracted all the references to also and sound. There are a lot of errors. Hope it helps. ** Attachment added: "text file containing extracts from syslog" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1931756/+attachment/5504417/+files/sound.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931756 Title: [XPS 17 9700, Intel Kabylake HDMI, Digital Out, HDMI] Playback problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1931756/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
