Obviously depends on the laptop and the amplifier/DAC chip in the laptop, but in general, it’s about 2Vrms with an output impedance of about 20 ohms. That gives you a short circuit current of about 100mA. You can get maximum power out with a matched impedance (also 20 ohms), and that gives you about 50mW.

As for the laptop jack output, it really depends on whether the jack is set to line-level output (around 0.15V) or headphone-level output (usually 0.5v), although it could reach 1v in some cases. You should be able to find the tech docs for the audio codec of your laptop.
What is the typical max voltage out of a PC speaker Jack?
https://electronics.stackexchange.com/questions/37926/what-is-the-typical-max-voltage-out-of-a-pc-speaker-jack
I got +/- 1.5v (3.0 volts peak to peak). This was not under controlled conditions with a known audio source. I would guess that the output could peak at higher than +/- 3v (6v peak to peak). Show activity on this post. In some cases [ not extreme cases] due to the ground looping it may get up to more than ~60V.

As you have already discovered, different devices have different output levels. The power that can be provided by your PC is, for example, X milliwatts. As the PC power supply can give up 12V to the soundcard, the XmW could well be generated with an emphasis on the voltage rather than the current. Some top end motherboards (the latest Asus ROG boards, for example) boast a …

How can I increasing output voltage/amplify my laptop's sound card headphone jack. Tia sal2 Greetings All I'm generating different sound waves using my laptop and outputting the sound via my laptop's sound card headphone jack. I need to increase the output voltage / amplify the output signal to at least 5v while not adding to much noise to the ...
