Hi everybody,
Sorry I'm french so I have to explain my problem simply.
I have an optical output connected to an ampli but this output is always in stereo.
My pc is a notbook Acer 7730G and it's specified :
But under Ubuntu I have digital stereo duplexTrue5.1-channel surround sound output
High-definition audio support
S/PDIF (Sony/Philips Digital Interface) support for digital
speakers
Of course, I would have surround effect !
I think it's about passthrought option but I don't know where I can modified it.
