Slight annoyance with my set-up Acoustic Solutions DS1233 Home Cinema connected to VCR , DVD + Digifusion Digi-box + Samsung Analogue TV On normal Digital TV listening ( output through the Digi box's RCA Audio outs ) there is a " double pop " noise when a program switches to an advert or from advert to advert. No problem with continuous listening during programs , only when programs start/stop i.e commercial breaks. This popping noise only comes from the sub unit. Sub is about 12" from TV Any suggestions how to cure this ? Thanks in advance.
