I have a Seiki LC-32G82 and the speakers are quiet. I wanted to hook up my 3.5mm speakers but there is no output for that. There are two RCA outputs, "coaxial audio" and "s-video". I found this adapter for RCA-to-3.5mm (http/www.amazon.com/gp/product/B003L14XTO/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER) and thought it might work but the video is from HDMI and I have no HDMI audio outputs. I have read reviews though that say it didn't work when they had a similar set up but want to be sure before I buy anything. Should I get an HDMI-to-HDMI+audio converter instead (http/www.amazon.com/J-Tech-Digital-Switcher-Selector-Extractor/dp/B00QJGAKCW/ref=sr_1_4?ie=UTF8&qid=1438716780&sr=8-4&keywords=hdmi+splitter+with+audio)? I also have a ps3 that is HDMI that would be nice to use the speakers with as well, so if I need the adapter is this the right one? Thanks.
