I think I'm using pulse. Also jack. jack suspends pulseaudio, I believe, when
it runs.

My loopback device is set up when I manually insert the module ( "modprobe
snd-aloop"). But it boots up without any snd modules initially.

Discard all samples (playback) or generate zero samples (capture)

Loopback, Loopback PCM
Default Audio Device

The directory has: card0 cards devices Loopback modules pcm seq timers
version
cat /proc/asound/cards
0 [Loopback ]: Loopback - Loopback
Loopback 1
There's just the loopback device.

there are no recent errors, with the most recent recompiling.
Like I said, the kernel module file "snd-hda-intel.ko" is missing from my
latest /lib/modules/. I believe that's the file that would set up my audio
card. But how to generate it? I'm assuming it was there before I removed my
pre-compiled alsa-utils,etc, to make way for my local build (?). But then my
local build failed to generate the new version of this file (?)

Et bien — c'est ma façon de me taire.
