I noticed the same issue with no sound myself earlier, and I have been looking into what might be the cause. Strange thing, as no changes have been made to QSpot that should cause such a problem. In my case it seems that in case I use auto-login, I do not get any sound, but in case I login manually then sound always work. Have this issue appear with the latest (0.9.9-4) QSpot version, or already with some earlier one? Are you both using latest CSSU by the way?
