Hello,
Comments inline. I'm leaving the ALSA-specific bits to David/Tanu since
they are more well-versed with that code than I am. I've been using this
code on the Galaxy Nexus, and things seem to work fine, which is
nice. :)
Thanks,
Arun

Should Headphones be higher priority than speaker by default? That way a
sensible default will be picked if both ports are available.

You can drop this function entirely and use pa_str_in_list_spaces().

This and subsequent functions seem to be indented at 80 columns. Other
places seem to follow PA coding style of 128 columns.

Use pa_streq(). I'll likely miss some call sites of strcmp(), so do

Maybe I'm missing something obvious, but why not convert the conflicting
and supported devices lists from a string list to a PA list and avoid
all this repeated dynamic allocation?
