Regarding

"Tue Mar 29 13:07:39 2016: creating alsa driver ...
hw:0|hw:0|1024|2|44100|0|0|nomon|swmeter|-|32bit

Tue Mar 29 13:07:39 2016: ERROR: ALSA: Cannot open PCM device alsa_pcm
for playback. Falling back to capture-only mode"

I recommend to open a terminal and to run

  aplay -l;printf "\n###\n\n";arecord -l;printf "\n###\n\n";amidi -l

then the original poster should select the output, right click, chose
copy and paste it to an email, to send it to the mailing list.

Perhaps the original poster has several audio devices and maybe at least
one device might provide record ports only or just midi ports. Since the
order of cards could change with each reboot, it requires either to
edit /etc/modprobe.d/alsa-base.conf, for example

  $ cat /etc/modprobe.d/alsa-base.conf 
  # ALSA module ordering
  options snd slots=snd_hdspm,snd_ice1712,snd_ice1712

or instead of choosing "hw:0" to chose an audio device by it's
dedicated name.
