What is the highest voltage level from my laptop sound card?

I am pretty much sure all laptops regardless of products have same specification as to the out put of their signal levels from the sound card. Any ideas what the maximum output voltage could be?

Not necessarily!





Output is usually measured in watts at the speaker connections, not volts.





The Line-out "standard" is 1v peak-to-peak on most systems except those designed to drive many speakers, (like restaurant background music), which are usually either 75v or 150v to avoid "line loss" in large systems with long runs, which then use special transformers at each speaker to convert back for the speakers.
