hi all, hope doing well,
can anyone tell me what might be the power of a signal coming out of a sound card. i am using a sound card of 192k in my project and i need to know the power level of signal coming out of it.

Experience with several computers has shown I can't hope for loud volume from an ordinary speaker. I'm lucky if I can get loud volume in my headphones.

This isn't much power. About 1 VAC.

If we assume 8 ohm speaker load, then that makes 1/8 ( V*V /R ), or 125 mW available power.

Just a rough estimation.
