[SVD1121C5EB, Realtek ALC275, Speaker, Internal] Playback problem internal speaker. Headphone output fine.

[Aaron Fleming]

Have checked with alsamixer to ensure all channels have volume, and 'auto mute' is disabled.
Headphone output works fine. Speaker output does not.
Tried alsa force-reload then rebooted, still not sound.
After this, the two buttons to test audio in Audio settings don't activate. (Before alsa force-reload they both looked like they were trying to play audio, now no).

Only have one output device listed, named "built-in audio"
