A new day, a new install of Ubuntu 16.04 Server Edition on the laptop (Dell Latitude E6500), and a new problem. You're gonna love this one!
Sound works perfectly,
as long as I'm logged in on tty1.
Literally, I log in through tty1 (console on the laptop), and then ssh from my desktop to the laptop, run flite -t "audio test", and the laptop says "Audio test," as expected.
BUT, if I log out of tty1, run flite -t "audio test" from ssh, and I get this:
Code:
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4292:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory
ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings
ALSA lib conf.c:4292:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory
ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name
ALSA lib conf.c:4292:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
ALSA lib conf.c:4771:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib pcm.c:2266:(snd_pcm_open_noupdate) Unknown PCM default
audio_open_alsa: failed to open audio device default. No such file or directory
And it's not just flite.
NO audio through aplay, mplayer, etc. Same error until I log back into tty1, and then it plays perfectly again.
Since this laptop will eventually be mounted in a robot, logging into the local console would be extremely difficult, to say the least.
There's a slight difference if I run aplay -l while logged in vs while not logged in as well:
Code:
(Logged in) aplay --list-devices
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: 92HD71B7X Analog [92HD71B7X Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
Code:
(Logged out) aplay --list devices
aplay: device_list:268: no soundcards found...
Additionally, this pops up in /var/log/syslog when I log out:
Code:
Dec 2 08:18:32 timothy systemd[1]: getty@tty1.service: Service has no hold-off time, scheduling restart.
Dec 2 08:18:32 timothy systemd[1]: Stopped Getty on tty1.
Dec 2 08:18:32 timothy systemd[1]: Started Getty on tty1.
Dunno if it has anything to do with it, but it's there.
Running uname -r gives me: 4.4.0-87-generic
And lspci shows everything it should:

So what's causing this, and how do I fix it?
