How can I get Kmix to control volume through HDMI?

view story

http://forums.opensuse.org – I have my Acer Revo R3610 PC connected to my LCD TV through HDMI. The sound works but I cannot control the volume from Kmix. I've added the IEC958 channel to the channels in Kmix but it doesn't provide a slider for it. Only a mute. The master volume slider has no effect at all. Is there any way of controlling the volume when connected through HDMI? I ran the alsa diagnostics script (/usr/sbin/alsa-info.sh) and uploaded it here. Here is a quick summary of my Alsa version, sound module loaded and sound card details. Code: mediacentre@mediacentre:~> cat /proc/asound/version Advanced Linux (Distributions)
