Probably interference from the CPU's power-saving. Try e.g.:
processor.max_cstate=2
In grub's boot commandline (as shown by: cat /proc/cmdline)
Interesting! I tried both
root=/dev/sda2 ro quiet init=/bin/systemd processor.max_cstate=1 initrd=../initramfs-linux.img BOOT_IMAGE=../vmlinuz-linux
and
root=/dev/sda2 ro quiet init=/bin/systemd processor.max_cstate=2 initrd=../initramfs-linux.img BOOT_IMAGE=../vmlinuz-linux
but it had no effect from what I can tell. Are there any other such settings I could try? I found this page on a search but I'm no wiser from it.

But more to the point: The alsa wiki has a list of cards and reports of their support on linux.
Edit: to add link.
]]>Would a Creative Sound Blaster X-Fi HD USB do the trick? I recall that manufacturer got a lot of flak previously due to incompatibility with Linux... I can't pry apart the machine, obviously, so it's got to be something that would work on a majority of low-end bulk-ordered laptops without voiding any warranties or the like.
Edit: Marking as solved, using an external soundcard works.
