I recently purchase a CSS2123/05 sound bar work all ok , but find that when you switch off the TV the sound bar goes into standby and when you switch the TV back on you need to also switch the sound bar on, select the source, re-set the voloume "anoying" each time cant this unit be adjusted to stay on all the time? it is conneted via a 3mm jack plug on TV to the two phono plugs on sound bar
