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.
