The HDMI sound device might not be detected automatically when booting the computer without the television connected. I hope this instruction will help you 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
