[PROBLEM] Audio stopped working with HDMI

[dmantampfl]

Hi all,
few days back all of a suddent sound stopped coming from my raspberry PI. I am running XBian Beta 1.1. I connected a second with same disk, it is still the same issue. Reinstalled xbian and copied only userdata from old disk. No change. Is it possible that cable could have damaged. I don't have any other HDMI source or cable right now to test what went wrong.

In system sessings.
Audio Ouput : HDMI
Speaker configuration : 2.0
Boost volume on downmix : Yes
Output stereo to all speakers : Yes
Dolby Digital (AC3) capable reciever : Yes
DTS capabale reciver : Yes
