We tried different kernels (4.15.0-oem, 5.4.0-64, 5.4.0-65 and 5.11+), the audio controller can't access the codec stable. More or less, there are some errors when controller access codec.
Although there is this kind of error, that doesn't mean the audio doesn't work 100% chance, the audio could work sometimes. This issue is not a regression on the kernel 5.4.0-65. I doubt this is a hardware issue/BIOS issue specific to this SKU. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1913014 Title: No audio on XPS 13 9370 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.4/+bug/1913014/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
