Pass thru error messages for audio

[magdesign]

Option to pass thru the omxplayer error messages e.g. alsa interface is chosen but there is no alsa interface attached:

/usr/bin/omxplayer-sync -mu -o alsa:hw:1,0 /media/internal/video/* will just hang, while:

/usr/bin/omxplayer -o alsa:hw:1,0 /media/internal/video/*

outputs an error and then hangs:

ALSA lib pcm_hw.c:1713:(_snd_pcm_hw_open) Invalid value for card
