No, I have no such file.

Yes, I mentioned in the first post that I created a rule under
/etc/modprobe.d/ to disable HDMI audio output through the integrated chips.
But you added another reply so you probably noticed that I wrote that

It *does* work, however, not as it should.

No, I meant specific commands to test those CLI players with the default
ALSA device (that has that issue with high CPU usage). Or at least to give
some output with which we could have a clue what's causing the CPU usage.

I did, and unsurprisingly it did not help, the same high CPU usage on the
default device, the specific subdevice monopolises the sound card, and on
top of that, most applications that don't offer any settings for setting
which audio card/device/subdevice to use are left without sound because
they automatically choose the first card, which is the HDMI output.
