HDMI sound: omxplayer works but not aplay

Question

I want to use text-to-speech programs like festival and espeak, but they don't produce any sound.

I'm able to play sounds with omxplayer, but aplay, festival, and espeak are all muted.

I've tried tweaking /boot/config.txt and modprobe'ing, to no effect. Any tips?

pulseaudio is not installed.

Using official Raspbian (wheezy) on a Raspberry Pi model B+.

Answer 1

Fixed it.

1. Connect Raspberry Pi to HDMI TV.
2. Boot Raspbian.
3. Edit /usr/share/alsa/alsa.conf.
4. Change the line pcm.front cards.pcm.front to pcm.front cards.pcm.default.
5. Reload alsa: sudo alsa reload
6. Confirm audio is now working: aplay /usr/share/scratch/Media/Sounds/Animal/Kitten.wav
