Portege R500 (PPR50E) speaker does not mute when headphone connected
I am using Toshiba Portege R500 (PPR50E) with Windows XP Professional (SP3).
The problem is the laptop speaker doesnot mute when I connect the headphone. The audio is coming from both headphone and the laptop speakers. This is verymuch irritating when doing voice chat. Is there any solution for this issue?
