I've reinstalled Windows onto my main desktop, and I can't get any audio through the left channel.
I've tried my speakers and the tele, both of them only have right channel. If I change the balance to put right to zero and left to full, I get no sound at all. Nothing hardware-related has changed, only software.
I've got no idea what to try next - any ideas? It's Azalia by the way, built into the motherboard.
