Hello,

First, i pressent me:
My name is Fran, and i'm a complete blind a debian user (studding
systems administration).
  Now, i pressent your the following problem.

after download the rc1 of installer for buster, the installer speech
on another machines (VM machines for vmWare example) but, no gives
text to speech on hp 250g2 after accessibility mode enabled (pressing
s during boot).
  This problem ocurs after listen a single beep (bios mode) and twice
beep (UEFI mode). in same cases, no speech.
  If your need, the sound card controller is:
Intel(R) 7series/C216 chipset high definition audio controller).
 Note: in debian jessie and stretch installers, the speech
functionality is success

Fran.
