I reproduced this once, but it was while switching HDA and I2S modes, so i'm suspecting that it might have been related to the default device being selected. Are you still able to reproduce this on demand?
When I did reproduce it, xev did pick up keycodes, but no indicator in the popup when they were pressed. -- 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/1423415 Title: [XPS 13 9343, Realtek ALC3263, Speaker, Internal] Volume hotkeys stopped working in Ubuntu 15.04 Status in Dell Sputnik: New Status in alsa-driver package in Ubuntu: New Bug description: Volume hotkeys were working and now they're not.
