--- Comment #1 from Tanu Kaskinen <tanuk at iki.fi> ---
PulseAudio uses alsa devices like "front", "surround51" etc. The "hw" devices
are only used when nothing else is available. In this case I guess the "front"
device is available, so PulseAudio uses that, but it refers to "hw:1,0", while
you'd like to use "hw:1,1".

To make PulseAudio use "hw:1,1", custom configuration is needed. Here's some
documentation for that:
https://www.freedesktop.org/wiki/Software/PulseAudio/Backends/ALSA/Profiles/

A proper fix would require adding some new functionality to alsa so that
PulseAudio could automatically figure out that there are separate PCM devices
for headphones and speakers.
