No Sound Ubuntu 10.04 Toshiba Tecra A8-EZ8311

I have tried many of the fixes referenced, including changing the driver reference in the last line of the alsa-base.conf file using all of those list as solutions to the issue (fujitsu, hp-bpc, hp-bpc-d7000, hp-tc-t5735, hp-rp5700, benq, benq-t31, hippo, hippo_1, sony-assamd, toshiba-s06, toshiba-rx1, tyan, ultra, lenovo-3000, nec, basic and auto) but still no sound.

Any help you can provide would be appreciated.

Some of the details about my set-up:
