Hello, With extensive digging . I found a fix for no sound Toshiba A205-s4557 per another forum.Version is Debian 2.6.18 etch.This fix was for Ubunto but the procedure works for Debian too.
)Download alsa-drivers, alsa-firware, alsa-lib, alsa-util version 1.0.14 from ALSA.org and extract it into a directory named ALSA in desktop or your home
2) Replace patch_realtek.c and hda_proc.c in the ~ALSA/alsa-driver-1.0.14/alsa-kernel/pci/hda with the new files (I am attaching both)
3) Then do sudo ./configure sudo make and sudo make install in the following folders according to the order specified (order is important) ALSA lib , ALSA utils ALSA firmware and lastly ALSA drivers.
hopefully you will see no errors.
Unmute the mixers see the following link for how the mixer will look like
the headphones channel would control the external speakers and line in channel will (unfortunately/fortunately) control the inbuilt speakers.
I am extremely happy thanks to Chris Cheney and Brian Mount once again.
I think I am going to freeze all updates till this gets patched in repository.
Good night and enjoy.
