no sound when connecting with usb modem

[mkhuda]

dear all,
i have a problem on my windows vista ultimate 32 bit, when i connecting my ZTE MG880 (CDMA Modem) on my laptop especially at starting modem application, suddenly the sound becomes dead ...
I use Compaq CQ40 322 TU...
And what the problem ?
Thank's

Has this issue happen in the past, or just with vista? (and isn't this meant to be w7 forum?)

Anyway, the sound could have now been going from the modem, which i have not come across before if this is true. Is there a headphone jack in this modem?

 

[mkhuda]

sorry, i mean windows 7 ultimate...
there is no headphone jack in these modem...

i'm upgrading from vista home basic to 7 ultimate, and i found these problem...but if the modem is not connecting with laptop, the voice is no problem,

Are there any issues with your devices/drivers in Device Manager?

 

[mkhuda]

no issues in device manager...

the sound is dead at this step...

Would you have sound if you plug in a headset into your laptop? I have not come across this situation for a modem, but i do with devices which has headset jacks.
