Sound card not detected by the incoming Debian installer for Debian 10

[Didier Spaier <didier@slint.fr>]

Hello,

root[/home/didier]# lspci -knn|grep -A2 Audio
00:1b.0 Audio device [0403]: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20] (rev 04)
	Subsystem: Lenovo 6 Series/C200 Series Chipset Family High Definition Audio Controller [17aa:21cf]
	Kernel driver in use: snd_hda_intel
	Kernel modules: snd_hda_intel

Weekly image ISO: debian-testing-amd64-DVD-1.iso (dated 14 June IIRC).

I would expect that /lib/debian-installer-startup.d/S38espeakup detects
one sound card, so just starts espeakup.

Instead, it is stuck in the 30 seconds loop then give up.

I attach S38espeakup and the Slint script probe_sound_cars with the same
purpose but that does detect the card.

However I don't know if the difference comes from the script or on how
/sys is populated or from any other reason.

I will provide additional information upon request.

Best regards,

Didier

PS additionally the 'sleep' from BusyBox doesn't accept a 0.1 argument, but that's minor.
