Audio Over HDMI Inconsistency

[AirborneUnicorn]

Hello, I've been getting acquainted with my Raspberry Pi and Linux (Mostly through trial and error) but one thing I simply cannot figure out is my situation with the audio over HDMI. While messing with OMXPlayer, I discovered that audio works if I force it through HDMI, and the same with ./hello_audio 1. Under normal circumstances, audio seems to default to analog despite having changed the config.txt file to force HDMI. I have read as many forum posts on audio over HDMI issues as I could find, but none seem to help. Are there any settings I should look at on the HD TV I'm using? How do I make it default to audio over HDMI? Sorry if this has been posted many times over, but I can't fix this for the life of me. Any help is appreciated. Thanks.

Neither omxplayer, nor hello_audio try to auto detect the audio destination. You need to choose on he command line.
ALSA is different, it does try to auto detect.

Oh, alright. So, if ALSA is not auto detecting the correct thing, how can I fix this?

Des ALSA work when manually selecting HDMI output:

Yes, when manually forcing it. But un-commenting the line hdmi_drive=2 does not fix it.

Try this. Open a terminal and enter 'sudo amixer cset numid=3 2'
It is the 2 that is important here. 0=auto, 1=analog 2=hdmi

Thank you! I'll try it in the morning, and report the results afterwords.
