Hi, I am haveing a SBLive 5.1 with FC3. I am not getting my mixer controls properly. It simply does not work. ALSA speaker test produces sound only from 4 channels. It didn't produce sound from center and woofer. There are lot of cntrols in the mixer and I don't understand what to mute and what to unmute. I trie dalmost all possible combination and didn't work. BTW, all my speaker connections are OK. I could get the test orking fine in WinXP. Deekshit M
