[Satellite C50-A, Intel PantherPoint HDMI, Digital Out, HDMI] No sound at all

[Bhupendra Siyag]

Running dual-boot with Windows8. When I rebooted into Ubuntu, sound didn't work at all. Reboot might fix the problem but I'd like to know how to troubleshoot without rebooting.

Seems like a sound driver issue and I have some very important tiger maulings to watch on youtube.

Thanks
