Salutations,

I recently hooked up a 5.1 surround sound receiver to my Haswell setup
via HDMI. I used the sound manager in gnome to set the system to output
5.1 surround sound. However, while testing each individual speaker using
the gnome sound settings, I found that front speakers were echoing
content to rear speakers (with a small delay). I also noticed that if I
set the fade to rear, I would lose all front speaker output. Moving the
fade to the front reproduced the echo  again. This is noticeable in any
5.1 audio I play as well. Has anyone experienced this and found a solution?

Regards,
Mark
