Hi all. I had a sudden doubt about my left and my right. I was firing up jack (through qjackctl, lazy i am) and then 'alsaplayer -o jack somefiles*', getting the output playing fine. But then when i tried to mute a channel with the balance in alsaplayer, the unmuted channel was sent to both speakers. Even when disconnecting the left cable, the right channel was still outputed on both left and right ?! I found the trick while writing this email, so i thought i should let you know. The culprit was the 3D Control switch of my emu10k1, which was set to on. Note for later, i won't use these one and a half D things again :) Cheers, piem
