Typical Sound Card Stuff

Afternoon watch, 8 bells (4:00 pm)

Today my boss came in to my office and asked if I could find out the output voltage and impedance for his laptop's sound card.

Hardware specs tend to not go that in-depth. Finding the manufacturer of the sound hardware may work, but I ran in to several dead ends trying this.

In the end, I found a website dedicated to using your sound hardware as a cheap oscilloscope. Turns out, they've done the research and listed averages, which ended up being good enough for my boss.

The answer? Typical output voltage for a computer line-out jack is 1.5-2.0v. Impedance tends to be between 30 and 400 ohms. Just in case you needed to know.
