@sami I don't agree. My previous laptop Dell Insprion 17R 7720 SE has nVidia GT650M + Intel HD4000 and works well in Linux because I simply turned off nVidia. The new laptop Dell AW17R3 has the built-in HDMI port hard-wired to the nVidia GTX 970M GPU which requires installing nVidia drivers.
On the previous laptop headphone jack works perfectly. On the new one analog and digital sound is supported and doesn't work out of the box. On the previous laptop HDMI was full pixels with HD4000 driver. On the new one there is about 40 pixels underscan all around. The bigger problems (which is are technical challenges which I like) are NVMe M.2 SSD setup, Windows Subsystem for Linux (WSL) under Windows 10 (W10) and converting Linux bash scripts on a shared NTFS parition when dual-booting between Ubuntu and W10. Adding hybrid support to said bash scripts with Powershell commands when running under W10. Compound the challenges with installation of VcXsrv and Ubuntu desktops running Linux GUI apps (like Firefox, LibreOffice) on W10. If I didn't want technical challenges, I'd throw away my laptops and go to the library. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1377653 Title: HDMI sound output not detected / NVIDIA optimus laptop Status in alsa-driver package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: Hi, not sure if this is an alsa or nvidia/nouveau bug.
