Ish: Sound doesn’t work using ALSA and no playback device found

[k16blfurm]

Really dumb request but I was curious. I used this guide to install ALSA (sound control software and utils). Anyways, I followed this guide below:

https://wiki.alpinelinux.org/wiki/Sound_Setup

And I ran and got this on my iPhone:
`B-Iphone:~/jdk# speaker-test

speaker-test 1.1.9

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
ALSA lib confmisc.c:767:(parse_card) cannot find card '0'
ALSA lib conf.c:4568:(_snd_config_evaluate) function snd_func_card_driver r

rectory
ALSA lib pcm.c:2564:(snd_pcm_open_noupdate) Unknown PCM default
Playback open error: -2,No such file or directory`

Not a big deal this doesn’t work. Just wanted to document it.

Seems like there is no sound card driver support.
I am using an iPad gen 6, and I get the following:

iPad:# aplay -l
aplay: device_list:272: no soundcards found...

Would be awesome if this can be done for purpose of making the iPad a viable sound synthesis tool with SuperCollider etc

+1 would be awesome to be able to play audio. Could use command line audio players etc.
