Audio over HDMI - hello_audio.bin works but not aplay

Question

I'm having problems getting audio over HDMI working correctly (running ArchARM). I have in my /boot/config.txt:

hdmi_drive=2

I compiled hello_audio.bin and ran it with 0 and 1 as args, both work (through the TV and the jack)

Sound over the analogue jack works fine with aplay when I switch with:

amixer cset numid=3 1

But I can't get aplay to play wav files over HDMI (I switched to hdmi with amixer cset numid=3 2)

Just to update: I can play mp3 files in mpg123/mplayer over HDMI but still no luck with wavs.

this worked for me:

omxplayer -o hdmi audiofile.wav

it seems that aplay doesn't really do a good job sending audio through hdmi in other formats either, it turns everything to mono, 8bit, and 8000hz or something. Anyway, that worked for me!

I'm pretty sure you have to specify the device with aplay like this:

aplay -D plug:hdmi music.wav
