No sound after login on mate desktop.

[Linux for blind general discussion]

Hi!
I use Debian Stretch here with mate desktop.
Maybe i’ve didn’t install things correctly but when i am prompted for login i hear the speech asking me to enter my name and password.
When i am logged in i don’t hear any speech or any sound at all.
I have gone through all settings in regards to sound and everything seems to be set as it should.
I use a built-in realtech soundcard and i am not sure if this is the problem or if there is no drivers installed for this card or what.
Any hints on what to do?
Thanks.
