I can tell when my CPU usage spikes because it causes a hum through my speakers, so this does not seem that far-fetched.

It's just means you have a shitty audio tract with not enough shielding. Move to SPDIF/TOSLINK.

    I have an external audio card, if I put it on a laptop I can hear the modem-like sounds. I wonder why it is so sensitive, should not DAC produce strong signal that cannot be easily affected by radio waves?

    Also my headphones are extremely sensitive. I can touch the ring and sleeve of a jack with a finger, and touch a metal bed frame with a tip and I hear quiet clicks as I move the tip along the metal. Sometimes I do not even need to touch the jack with a finger. It doesn't work with small objects like a knife though.

      Assumption: it's a USB one so it's not a good one in the first place and it shares the common ground with the the whole laptop.

      And this is not the case of 'stronger than', it's 'strong enough to be caught up by anything resembling an antenna'.

      You hear the interference because some analogue tract of your system:

      Do transmit the radio waves everywhere

      Does receive the inference from the all electric things around.

      And now I'm skipping 'cuz I'm inna a bar and it's more interesting.
