Hello, i downloaded the: debian-buster-DI-rc3-amd64-DVD-1.iso from: ftp://cdimage.debian.org/cdimage/buster_di_rc3/amd64/iso-dvd/debian-buster-DI-rc3-amd64-dvd-1.iso after, i writed this file on a USB drive with dd command ussing the following sintax: dd if=debian-buster-DI-rc3-amd64-dvd-1.iso of=/dev/sdb after wrote it, i connected the USB drive on a USB port of my laptop and boot this. After boot the laptop, i can listen the twice beep's if i use UEFI. After twice beep's, i press "s" for start speech installation setup but, the speakup not start speaking and, the installer not be accesible. This problem also ocurs if i use a bios boot (one beep onli). the speakup don't start speaking too.
Also, this problem of accessibility was apeared on alfa5 of installer and rc1. I can't be tested the rc2. But, with the mini.iso image of Samuel thibault the speakup start's without problems. I was reported same problem or bug on the rc1 release. These problems was repeated on rc3 release. Fran.
