Understanding voltage levels on 3.5 mm audio output
https://electronics.stackexchange.com/questions/298573/understanding-voltage-levels-on-3-5-mm-audio-output
In the hope of using the standard 3.5mm audio output found in your average PC/smartphone to control (not power) a DC motor, I was measuring the voltage between GND and Tip and noticed the following: When no audio is playing, there's a voltage of about 2 mV.

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.

Answer: 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 gi...
THE RELATIONSHIP OF VOLTAGE, LOUDNESS, POWER …
https://www.gcaudio.com/tips-tricks/the-relationship-of-voltage-loudness-power-and-decibels/
Looking at the chart, and starting at the left, we can see that an increase of 3dB results in a voltage increase 1.4 times the original, a doubling of power, and yields only a subjective increase in loudness only 1.23 times the original. To get a doubling of loudness, it is important to note that an increase of 10dB is necessary.
How to connect your computer audio output to your …
https://www.ramelectronics.net/howto-pc-audio.aspx
The easiest way to connect the audio output of your computer is to use the "line" output of your sound card. We recommend a stereo 3.5mm mini phone plug to dual RCA cable or mini plug to dual RCA jack adapter with a RCA jack stereo cable to go to the audio input of your sound system, such as the "aux" input. The longer the length of the cable ...

Measure the output voltage and note the amplitude. Divide it by root 2, thus get you the rms of the voltage. The temporally linear mean value of the achievement is then (rms of …
What Voltages can I expect from 3.5mm Audio? - reddit

Most audio equipment will put out rms voltages around 0.3V while playing music, but make sure your inputs will be able to handle the possible 3V peaks without significant distortion as most music will regularly hit those peaks for short fractions of a second. EDIT: bad formatting. you should see +/-2v at most.

sound card voltage input That's right, the sample rate of most sound cards goes up to only 48 ksps. A 38.4 kbps signal would look badly jittery. Some fancier sound cards go up to 96 ksps or even 192 ksps. The waveform would look better, but still jittery. Also remember that most sound cards are AC coupled.
