I have an optical cable going from my PC to a digital AV receiver which is in a 5.1 surround sound config.
I am running a dual boot with win7 (surround sound works fine) and have just updated to the latest 32bit release of Ubuntu. In system settings->sound under the optical/SPDIF option, I have no means of selecting speaker config?! The default stereo works just fine I might add...
Any help is much appreciated!
