Ardour failed to create new sessions with ALSA, at no time I tried to
open an existing session.

1.
$ ardour4
bind txt domain [gtk2_ardour4] to /usr/share/ardour4/locale
Ardour4.7.0 (built using 4.7 and GCC version 5.3.0)
[snip]

2.
New Session

3.
Session name: test_session
Advanced options: untouched defaults
  [x] Create master bus 2 channels
  [x] Automatically connect to physical inputs
    [ ] Use only 1 channels
  [x] Automatically connect outputs
    [x] ...to master bus
    [ ] ...to physical outputs
    [ ] Use only 0 channels

3.
After "Open"
Audio System: select ALSA, was JACK

4.
'Start' and/or 'OK' results in "Failed to open audio device"

The audio device is unused, no web browser, no jackd or anything else
that could use the device is running.

[rocketmouse at archlinux ~]$ pidof jackd
[rocketmouse at archlinux ~]$ ps aux|grep jack|grep -v grep
[rocketmouse at archlinux ~]$
