[SOLVED] HDMI sound mixer, volume control. Is it possible?

Hi,
Is it possible to have sound volume control mixer when system is connected with HDMI cable?
when connected to speakers, there is mixer and I can control volume, but not with the HDMI.
Thanks!

Answer 1

I don't understand what are you trying to say, I don't have any volume control on HDMI output, only at stereo output.
EDIT: It looks like I have to implemement this: http://alsa.opensrc.org/Softvol
this is my .asoundrc
pcm.!default {
type hw
card 1
device 3
but I don't get how to configure it with softvol... any examples or suggestions?
this is NOT working for me:
pcm.hdmi_hw {
type hw
card 1 # <--- card number
device 3 # <--- device number
pcm.hdmi_formatted {
type plug
slave {
pcm hdmi_hw
rate 48000
channels 2
pcm.hdmi_complete {
type softvol
slave.pcm hdmi_formatted
control.name hdmi_volume
control.card 1
Thanks
EDIT:
after some time, I've found solution. It is really simple, I had to define default pcm.
pcm.hdmi_hw {
type hw
card 1 # <--- card number
device 3 # <--- device number
pcm.hdmi_complete {
type softvol
slave.pcm hdmi_hw
control.name hdmi_volume
control.card 1
pcm.!default hdmi_complete
