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 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).

While "line level" audio is typically 1 mW into 600 Ω, and this comes out to 1.1 V p for a sine, audio is far from a sine. Even if the spec is adhered to and you only get 775 mV RMS on average, the peaks can be considerably higher than 1.1 V. It is generally good to accept and handle without distortion peaks up to ± 5 V at least. Share

Headphone jack voltage range? - Audio - Arduino Forum

Values for pc line out: ~1,2Vrms ( = 1,7V peak ), so i think this one might go up to 1,75V peak. Values for Phone jack: ~0,520Vrms ( ~700mV peak), so this one might go up to 750mV peak. Cheers
