hello all, fired up my laptop earlier and suddenly i only have sound through 1 channel. it had been working just fine! looked at all settings i can think of and no luck. set up is acer timelinex 3830tg connected to a dell s2440l monitor via hdmi and logitech speakers pluged in directly to the monitor output 3.5 jack. tried another hdmi no change. if i plug them straight into the computer they play both channels so its not the speakers...... any ideas?
