hi,
unfortunatly, there is no 'Mic As Center/LFE' here on my machine...
it's a 'FSC D1607' board.
kernel plain vanilla 2.6.5 with included alsa stuff, compiled as modules.
debian sid: libasound2_1.0.3b, alsa-utils_1.0.3, alsa-oss_1.0.3a, etc.
playing music all goes well, analog output seems to be ok. but no use for my
micro.
any hints are very welcome
