My TV is an LGOLED55B6V. I'm trying to connect the TV's digital audio output to my PC soundcard's digital input, which is an SPDIF RCA socket. To this end I bought a converter, which has its own power supply. The converter accepts input via a Toslink cable, same as the TV's output. It outputs a digital signal via RCA. I also bought a digital coax cable with RCA connectors and a Toslink cable. After hooking it all up I'm receiving no signal at the PC, apparently. I'm left scratching my head. I'm thinking the SPDIF input signal may be a different format to the TV output signal. Any ideas? Thanks, Bernie
