[Bug 1421118] [NEW] [20-2110nz, Realtek ALC280, Speaker, Internal] Playback problem : headphones ok, speaker ko

 

Public bug reported:

Speaker doesn't work at all under Ubuntu, but sound through headphones is working fine.
The machine is an hp 20 all-in-one. The hardware is fine, as the speaker does work in the original Windows 8 that came with the computer. We played with alsamixer and tried to tweak /etc/modprobe.d/alsa-base.conf to no avail. We never managed to get a single sound through the internal speakers in Ubuntu.
