I'm trying to play a video with sound using Kivy video. When the Pi is attached to a 7" touchscreen it plays the soundtrack from the audio jack as expected. However, when attached to a VGA or DVI monitor/projector using HDMI converter there's no sound from the jack.
I've tried
amixer cset numid=3 1
on console and
hdmi_ignore_edid_audio=1
in the R.Pi config file but neither had any effect. I assume it's Kivy's version of gstreamer which is trying to play audio via the HDMI port.
Any ideas?
Let me know if you want anymore information.
