My setup is also a Acer Revo 3610 and I am outputing to my Sony TV via my Sony Reciever. I was having the same issue and found this solution here and here.

I changed my .asoundrc file to:

Code:

pcm.dmixer {
type dmix
ipc_key 1024
ipc_key_add_uid false
ipc_perm 0660
slave {
pcm "hw:0,3"
rate 48000
channels 2
period_time 0
period_size 1024
buffer_time 0
buffer_size 4096
}
}

pcm.!default {
type plug
slave.pcm "dmixer"
}

Now sound works over HDMI in both XBMC and in Firefox/Flash as well as xmame.

Additional info to help others here:
