BackSpace Beep in Ubuntu?

[Linux for blind general discussion]

Well, after trying regular Debian9, I am now in Ubuntu17.10 on my desktop, with 
a DecTalk U S B. I am so-far having these issues.
I would `love to have my backspace beep working. I would also like to add an 
access with the right+alt to consoles 13-24. Can some1 please inform how to fix 
these? I will write on the Speakup list about the DecTalk. Thanks so much in 
advance
