Selecting audio output used by omxplayer

[lurch]

According to usage/audio/README.md, omxplayer should output audio over whatever default audio device you've configured in raspi-config.
However it seems that when video is being displayed over HDMI, omxplayer ignores the value set by raspi-config, and to get audio playing over the headphone port I actually have to do 'omxplayer -o local la.mp3`.

Can somebody more familiar with omxplayer confirm this is indeed the expected behaviour? If so, I'll have a go at updating the usage/audio/README.md page.

omxplayer doesn't use default alsa setting (which is set by raspi-config).
By default it is in auto mode, which means if HDMI is connected and EDID reports audio support, then it uses HDMI, otherwise headphones.
"-o local" or "-o hdmi" can be used to override this.

Hello !

is there any command that i can make omxplayer always use aux?

Thank you !

This issue was closed in 2014 and your question is much better asked on the forums.

@popcornmix I have HDMI connected (and no 3.5mm plug connected), and running tvservice -d edid.dat && edidparser edit.dat reports HDMI:EDID has HDMI support and audio support. Despite this, no audio is routed to HDMI unless I use -o hdmi (which I'd rather not have to). What could this be due to? Is there a bug in omxplayer's HDMI detection, or is it something else?

@obskyr That sounds like a question for https://github.com/popcornmix/omxplayer/issues rather than this documentation repo.

Oh, whoops, it sure is. I thought I was there!
