Sennheiser PC 350 SE / Driver Issue

[lik3abau55]

Hi all,

Can't seem to get my new headphones up and running. Driver related mostly. Windows thinks there aren't any devices installed. Under sound and hardware the only thing listed nVidia HD audio. Under device manager there is only HD audio. Can't seem to get this to work. Help?

Thanks again.

Do you have an external USB sound card that you're using? The PC350's plug into a normal 3.5mm jack. You need to have adequate power going to them, though. Most on-board audio solutions won't have a powerful enough headphone amp. The PC350's have an impedance of 150 ohms. If your on-board audio isn't powerful enough, you will either need to get a sound card or a DAC.
