|Thanks for your response.|
I did try several 1/8 inch plugs and got the same results. When they are fully inserted there only right audio. Perhaps something went wrong with the input jack during recording. I noticed also that the card was not fully secured on the slot and was loose enough to move around slightly. I suppose some wiring may have come loose possibly on that jack. I am wondering if I can switch the rear with the front. though configuration, since recording requires the main audio out jack to work and all other outs are disabled.
