The standard for consumer equipment is .447V peak, and on professional equipment it’s 1.736V peak. Now Line impeadience can vary a lot, from 100Ω to 10kΩ, resulting in a current of 0.03013696W to 0.0003013696W, or 0.01736A, to 0.0001736A, on professional equipment. Not a lot of power.

The most common nominal level for consumer audio equipment is −10 dBV, ... Expressed in absolute terms, a signal at −10 dBV is equivalent to a sine wave signal with a peak amplitude of approximately 0.447 volts, or any general signal at 0.316 volts root mean square (VRMS). ...
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.

That chip is powered on an internal system voltage, likely on the order of ~6V. This means that the chip can drive the audio output to about 5V peak-to-peak (which is ~1.7V rms) into a high impedance. Since the audio amp chip has a lot of negative feedback, it has effectively a very low output impedance (<1 Ohm, i.e. it acts like a voltage source), but it may have an …
Solved: Headphone impedance level - Dell Community

The Microsoft Windows. Logo Program allows up to the equivalent of 100ohms in series. However, an output level of +3dBV. at the pin is required to support 300mV at the jack with a 32ohm load and 1V with a 320 ohm load. Microsoft allows device and system manufactures to limit output voltages to address EU safety.

Laptop TRRS headset audio connector pinout ? I have a new Dell Inspiron 14 3000 series laptop. I understand that the 'combination' TRRS jack on the right side of the laptop has combined mono audio in, and stereo audio out. Is there any documentation that shows the definition of the tip / ring1 / ring2 / sleeve connections and how they map to ...

If you get an output like this, reduce the power until you have a smoother output. For us, 55% of full volume (680 mV in) from the audio input gave us a clean output of 1.88 V at 20780 Hz, a …
iRig Pro I/O: No sound from iRig headphone jack
