I spoke too soon. Sound was working the first time I switched from 4.9 to 4.4, though volume couldn't be changed in the UI.
However, after I rebooted again (4.4 -> 4.4) I never got sound to work again. I'm now returning the laptop (for this and other reasons - e.g. battery life sucks) so I can't be any further assistance on this. -- 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/1649727 Title: No sound card detected with device: Intel Corporation Device 9d71 Status in linux package in Ubuntu: Confirmed Bug description: On a new Dell Inspiron i5378-2885GRY, the sound device is not detected by alsa, and the UI mixer shows a "Dummy" sound card. I've attached the ubuntu-bug dump for the laptop. I confirmed that snd- modules are loaded. The sound card is detected by lshw and lspci. It's a Intel Corporation Device 9d71. Fastboot is not enabled; boot is "thorough". The sound card *did* work on two separate occasions - i.e. was detected successfully. On all subsequent boots it is not detected.
