Hello,
I just tried the firmware - buster RC1 and RC2 and used the text install and my sound card was not detected.
firmware-buster-DI-rc2-amd64-DVD-1.iso
I also tried the latest daily release of Debian testing to see if this is fixed. It isn't.
My sound card is:
Realtek ALC3234
Right now i'm installing RC2 using high contrast install. No sound but I can see the screen.
Again, the Sid (non firmware version) build for last night also would not detect my soundcard.
This is a serious problem.
Regards,
David
