Apart from the aplay -L result at the end I got a lot of this:

...
open("/dev/snd/controlC2", O_RDWR|O_CLOEXEC) = 4
open("/dev/snd/controlC2", O_RDONLY|O_CLOEXEC) = 4
open("/dev/snd/controlC2", O_RDWR|O_CLOEXEC) = 4
...

and this

...
open("/dev/snd/controlC3", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file
or directory)
open("/dev/aloadC3", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or
directory)
open("/dev/snd/controlC4", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file
or directory)
open("/dev/aloadC4", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or
directory)
open("/dev/snd/controlC5", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file
or directory)
open("/dev/aloadC5", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or
directory)
open("/dev/snd/controlC6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file
or directory)
open("/dev/aloadC6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or
directory)
open("/dev/snd/controlC7", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file
or directory)
