Title:
[Asus X101CH, Internal speaker] No sound after update (Ubuntu
preinstall)
Status in “alsa-driver” package in Ubuntu:
Fix Released
Bug description:
This is a new Asus EeePc with Ubuntu preinstalled. The sound works out
of the box, but after an initial update the internal speakers stop
working. Audio via the headphone jack still works. A factory reset of
the system (which reinstalls Ubuntu from a recovery partition)
restores the sound but the next update (of Linux kernel) breaks it
again.
====
Current workaround:
Installing the latest DKMS package according to
https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS should bring the sound back.

I ran "ubuntu-bug audio" according to these instructions
