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.

So better check it carefully. Stick to 0.5 Vrms or less into the 'line in' input. Don't use it if it's only mic input ! Most laptop users use an external sound card ( USB audio ) like the M-Audio Transit for measurement/recording purposes. Even that has limited input I …

analog - What is the typical max voltage out of a PC ...
https://electronics.stackexchange.com/questions/37926/what-is-the-typical-max-voltage-out-of-a-pc-speaker-jack
I just measured the voltage from my smartphone headphone jack, which should be similar to what you'd get from a PC headphone 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).

signal voltage. A line in input might require 1 volt rms. A mic in input is at least 10 times more sensitive - 100 mv.
Sound card microphone - Hobby Hour
https://www.hobby-hour.com/electronics/computer_microphone.php
Most sound card microphone inputs require a minimum signal level of at least 10 millivolts, but some older 8-bit cards need as much as 100 millivolts. The typical impedance of the PC soundcard microphone input is in order of 1 to 20 kohms (can vary from card to card). The microphone type which works best with computer sound cards is the electret microphone.
Current levels of headphone output and PC mic input | All ...

I recommended adding a 3900 ohms resistor to ground at the mic input to draw 0.4mA DC so the pc senses "a mic". You wrongly show a DC voltage of 1V from your headphones output but it is probably a 1V peak audio signal which is not DC. Your pot is drawn wrongly and will be a VERY poor level control.

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 headphone-jack output of over 2V rms.
