why do the output of alsa-info (speaker not working) missing many
important info (e.g.alsactl,..amixer, sysfs pin cfg) ?
it is normal the speaker is muted when either one of the headphone jack
is plugged

[alsa-sink-ALC889 Analog] alsa-sink.c: Underrun!
this seem not alsa driver, it occur whe client did not supply audio and
server has nothing to write
in theory, the server have to call snd_pcm_foreward to recover
http://cgit.freedesktop.org/pulseaudio/pulseaudio/log/src/modules/alsa
you can add pa_alsa_dump() immediately after pa_log_info(Underrun!) to
verify appl_ptr is behind hwptr since those pulseaudio clients did not
supply sufficient audio to the server
the server seem have no ways to recover since it can not write any data which
affect the timing
it just hope the
module-udev-detect should skip card 1 when there is no pcm devices
