I am trying to get software speech to work on the Stretch net installer, on

Normally the debian installer loops over all sound boards it finds, to
prompt the user for which one he wants to use. If that doesn't work it
means there is a problem with the driver of your board. It's no use
trying to force using a given device: it already does so for each board
which was discovered.
So unfortunately it's most probably a bug in sound drivers, and more
information is needed to determine how to fix it, see
https://wiki.debian.org/accessibility#Debian_installer_accessibility
for the amixer commands to get output of, and the content of
/proc/asound/cards. Perhaps you can do so from some other image with
which sound does work, be it knoppix adriane or such.

I have found that for some reason the Debian sound board selector prompt
does not work on some Broadwell machines. Dave has a Broadwell machine
so I think this might be the problem. It seems to default to the HDMI
output and not loop to the Intel HD Audio card connected to the internal
speakers. I am not sure what is different, however, the sound board
selector on the Arch Linux live cd works with these Broadwell machines.
I copied the asound.conf generated by the Arch Linux sound board
selector to a flash drive and used that to do my Debian install. I
copied it to /etc and then restarted the espeakup process from one of
the extra terminals available when the Debian installer was booted. I
used a braille display for this task. It would be interesting to know
what Arch is doing differently. I don't know a lot about Alsa but maybe
someone with more knowledge in this area might have some ideas.
The script Arch Linux is using for picking cards can be found here.
Maybe someone who understands Alsa might be able to help with knowing
what this script and the one in Debian are doing differently.
