I heve following problems regarding the speaker volume settings in HTS 3538
i) How can I control speaker volumes while I am listening to CD music ? Must I have a TV ( HDMI or any other ) connection to get setup menu to do this ?
ii) When I tried to control the speaker volumes (when watching a DVD movie through a HDMI connection) as instructed in
the user manual by going to
setup --> Audio setup --> Speakers volume --> Here it says "Menu is disabled" !!!!!
Please advice why this happens and how to rectify this?

iii) Where can I get more information on 5.1 speaker volume control and tribble/base settings???

Thanks and regards,
