Bug#985696: debian-installer: Speech synthesis and Intel SOF firmware
some recent Intel sound cards require a firmware to work. This firmware
is packaged under 'firmware-sof-signed'. For reference, you might want
to look at the ITP .
As expected, selecting the "Speech Synthesis" option of the Debian
Installer fails on computer that have such sound cards, since the
required firmware is missing.
I tried it with my laptop. What happens is that the installer gets stuck
straight from the beginning, prior it can show any kind of GUI. All I
get is a black scree with the lines:
Please wait while we probe your sound card(s)...
No sound card detected after 3 seconds...
No sound card detected after 4 seconds...
And so on. I don't know if there's a timeout, after 30 seconds I
switched off the laptop.
I thought I could customize the ISO and add the firmware under the
'/firmware' directory, but it's not that easy. The step that probes
for sound cards is done in the initrd.
I don't have a solution to propose, I am merely reporting the issue in
case it's not a known issue yet.
