[2359CTO, Realtek ALC269VC, Speaker, Internal] No sound at all

[John Brondum]

Lenovo T530

No sound at all from the in-build speakers, headphones are fine

alsamixer -D hw:PCH shows speaker volume set to 0, but if I correct this using alsamixer the X server crashes on reboot and I am not able to start the machine

Complete fresh install.

Speakers worked fine using Ubuntu 12.04
