Problem: aplay under tty but no sound. aplay under xorg+pulse is ok. What has
missed?
Tried store alsactl from xorg+pulse environment and restore to tty environment,
restore without error messages, but still no sound.
When store again and compare found some part cannot be restored (see attached
alsactl results highlight)
OS: Ubuntu 14.04, kernel 3.16.0-41, alsa 1.0.25, pulse 4.0 (under xorg)
Under both environment:
(1) aplay command used: aplay -D hw:0,7 test.wav
(2) File /etc/asound.conf and ~/.asoundrc do not exist.
Under tty environment:
(3) alsamixer was checked all channels have unmuted
