The HDMI sound device might not be detected automatically when booting the computer without the television connected. With this you can try to make sure the drivers are always loaded.
First find your HDMI sound device, in this case card 1, device 3:
aplay -l
**** List of PLAYBACK Hardware Devices **** ... card 1: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0
Modify the following file to force-load the driver:
sudo gedit /etc/pulse/default.pa
Insert a line after module-alsa-sink, use option 1,3 for card 1 and device 3:
... #load-module module-alsa-sink #20130701,wjv force load HDMI sound driver card 1, device 3: load-module module-alsa-sink device=hw:1,3 ...
Reboot your system.
Test with aplay or with speaker-test (card 1, device 3):
aplay -D plughw:1,3 ~/Scripts/other/alarm.wav speaker-test -c 2 -r 48000 -D hw:1,3
Make sure the card is not muted:
sudo apt-get install gnome-alsamixer alsamixer
- F6 to select the device
- M to mute/unmute
