In the meantime, I found a simple patch, posted it to Debian and was told to
post it here, too:

There is already a provision for similar problems with other netbooks
using the "force-speaker.conf" profile set. This can be activated via
udev rules for the affected netbooks.

With this patch, the Asus EeePC R11CX and R011PX work as expected

I understand this, my question would be more precisely:

What is the difference between "switch = off" and "switch = mute"?

Could pulseaudio use "switch = mute" in the path file
pulseaudio/alsa-mixer/paths/analog-output-speaker.conf
so that there is no need for udev rules using the alternative
profile set "force-speaker.conf"?
