If you look at
http://tinycorelinux.net/17.x/aarch64/tcz/alsa.tcz.tree you'll see the following:
alsa.tcz
libasound.tcz
alsa-modules-6.12.15-piCore-v8.tcz
..which means that loading alsa will load alsa-modules-6.12.15-piCore-v8.
If, for some reason, alsa-modules-6.12.15-piCore-v8 is not present on your system, you can download it with:
tce-load -w alsa-modules-KERNELAfter loading alsa-utils, you should then see this:
aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: vc4hdmi0 [vc4-hdmi-0], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: vc4hdmi1 [vc4-hdmi-1], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]
Subdevices: 1/1
Subdevice #0: subdevice #0
This should give a sound output - either from a ternimal window or the console prompt:
speaker-test -c2 -t wav -l1Edit: I forgot to mention that this assumes you are going to output sound via hdmi - in order to perform the tests above you need alsa, alsa-utils and graphics-KERNEL loaded.
