Hi Experts,
I have recently got a new laptop with Windows 7 professional and facing a strange problem that sound becomes dead as soon as I connect USB modem to it and open the vendor specific software. I was using the same modem on win xp machine for last one year and did not face any such issue. I tried to install the new drivers for audio but problem still persist. Verifed the drivers for audio and modem and everything looks to be fine and working. Please advise.
