What is the output of:

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh

Thanks

I have sent the output as requested. Please note my sound now works. after many hours of fighting the system i performed yet another fresh install (this would be the 8th time) and then updated all software and continued to install my usual apps with no lose of sound. All steps I had taken are a repeat of the first times. I am unsure of what caused it to work with no issue this time but not the other as I used the same ISO as befor and the same boot device (android app driverdroid) live cd with 0 change in options selected. As mentioned by the label of the thread the install always went well and had functioning audio with no lose of audio after restarts or shut downs. The problem always would take effect after the first "Software Update" set fallowed by a successful restart. Upon boot sound device would change from " Speakers Built In" to "Dummy Audio" with no output via head phones or speakers. Thank you for your time.
